STRENGTH AND DURABILITY
•Aluminum dampers provide a prolonged and rust-free operational life over
galvanized steel types.
•Aluminum extrusions allow for intricate design features not possible with roll or
brake formed galvanized steel.
•Aluminum construction allows for additional strength by extruding
internal supports and thicker radii.
•Aluminum oxidizes to form a protective film. If the surface is
scratched, the film reforms.
(Standard damper is produced with a mill finish.)
M A I N T E N A N C E - F R E E
PERFORMANCE ACHIEVED
•Dampers are assembled using slip-proof linkage components that keep
blades aligned as per factory adjustment.
•Hexagon design feature of linkage and pivot elements allow for flat-on-flat
press fits that eliminate play and wear.
•Hard alloy aluminum (6005T5) linkage crank arm and pivot pin are doubly
secured by pincer-action and fastener.
•Large diameter (11/32" / 8.73mm) hard alloy aluminum (6005T5) linkage rod
connects the crank arms, which allows for a penetrating grip by the
cup-point fastener.
(Cup-point trunnion set screw creates a compression hard spot where it secures
to the linkage rod.)
•Trunnions are zinc-plated to provide a hard, smooth and
long-lasting rotating surface.
D E P E N D A B L E
"DUAL BEARING SYSTEM"
• TAMCO bearings consist of polycarbonate and acetal copolymer (Celcon) engineered thermal plastic resins.
• Dual bearing system is self-sealing, self-lubricating, and non-absorbent, which results in a totally
maintenance-free performance.
• Bearing materials meet or exceed tensile strength of 8,800 psi and flexural strength of 12,000 psi.
• Tensile impact strength of celcon is 70 ft.-lb./in.² and 145 ft.-lb./in.² for polycarbonate.
• TAMCO's bearing-to-bearing arrangement eliminates action between metal-to-metal and metal-to-plastic
riding surfaces. (Metal-on-metal steel, bronze or oil-lite bearings and metal-on-plastic nylon bearings have traditionally been
one of the weakest links in damper operation, requiring regular lubrication or eventual replacement.)
• TAMCO "Dual Bearing System" has a service life of 20 years plus.
(Replacement TAMCO bearings, which fit TAMCO dampers exclusively, have not been required in over 35 years, when dampers
have been installed according to manufacturer's guidelines.)

THERMAL INSULATING FEATURES & BENEFITS
Thermal breaks are the key to providing real
insulation value.

THERMAL BREAK DESIGN
+ 70°F
(+21°C)
Room air temperature
•TAMCO’s Thermally Insulated Blade combines an aluminum shell, R-6.6
polyurethane foam and three thermal breaks that result in a true insulation
value of R-2.29.
(R-value of an internal insulation medium only, is not indicative of the true R-value of a
blade as a whole and is virtually negated if the metal shell is not thermally broken.)
• Optimum placement of thermal breaks
isolates the warm and cold sides, yet still
maintains the blade’s structural integrity.
DRY ICE TEST
• Insulating foam is intrinsic to the
aluminum blade extrusion and therefore
shielded from the airstream.

E N H A N C E D
• Silicone side seals effectively resist
providing a path for the conduction of
heat from one side of the blade to the
other. (Stainless steel or aluminum side
seals create a thermal bridge for the
conduction of heat.)
T H E R M A L
PERFORMANCE
• TAMCO’s Thermally Broken Frame Dampers, along with “Flanged to Duct” installation, are all
that is required to achieve additional thermal protection, particularly for ducted exhaust, nonducted intake and high humidity applications.
(“Installed in Duct” mounting would negate the value of the frame’s thermal breaks
due to thermal bridging created by duct work.)
• TAMCO’s research and ongoing development programs continue to
improve and qualify damper performance, to aid in controlling the
effects of conduction, radiation, convection, and infiltration.
(Our aim is to produce units that interact efficiently with the building envelope.)
DRY ICE TEST
Dry ice: -109 °F (-80 °C)
Room air temperature: +70 °F (+21°C)
Thermal breaks are the key to
providing real insulation value.
S T A N D A R D
SILICONE SEALS
• The TAMCO Series 9000 BF offers silicone seals and blade gaskets.
(Silicone combines features of silica, silicate minerals, and organic compounds which result in
an inertness towards deteriorating effects of ozone, corona, weathering, and other forces, yet
incorporates an extraordinary flexibility.)
• Silicone is virtually unaffected by cold winter temperatures. Air leakage tests
performed in a cold chamber revealed that silicone seals allowed only a minimal
increase in the leakage rate from 40°F (4°C) to -40°F (-40°C).
(Cold box testing revealed no discernible change in flexibility or compressibility of silicone
between 70°F (21°C) and -40°F (-40°C).)
• Silicone’s superior dynamic fatigue resistance ensure prolonged sealing
longevity, plus phenomenal resistance to weathering, compression set, and heat.
TOP VIEW OF FRAME
(Even though general-purpose silicone can withstand 500°F (260°C), the upper operating
temperature of the damper unit, as a whole, is 185°F (85°C).)
• Silicone seals have an estimated service life of 30 years.

• An effective thermal break keeps the inside surfaces warmer. This permits
a higher indoor humidity without causing condensation. When condensation

(Condensation is a function of the damper surface temperature, the inside environment temperature
and the inside humidity levels. The inside surface temperature is affected by the amount of heat loss
through the blade (see temperature index number), and outside cold air infiltration.)

• TAMCO’s Thermally Broken Frame was independently tested and qualified in order
to clarify the impact and benefits that are achieved. The graph relating outdoor
temperature to surface temperature, plus indoor humidity at which condensation
will form, was constructed by calculating the Temperature Index.
Assuming 68°F (20°C) indoors, Temperature Indices are as follows:
80 TAMCO Thermally Broken Frame Option
61 non-broken damper frame
The graph will allow for estimates of frame temperature and humidity level which
can be supported without condensation.
• TAMCO’s Thermally Broken Frame is much more resistant to condensation
and freezing in applications where dampers must be closed in high humidity
environments (i.e., exhaust dampers or vents for pool buildings, computer rooms,
museums, etc.).
(Condensation will form on any surface whose temperature is below the dew point
(Temperature index is the ratio of the difference between the inside surface temperature (Tsi)
• Temperature Index = [Tsi - To] / [Ti - To] x 100 = 55. This equation can
be used to calculate the surface temperature for any combination of inside
and outside air temperatures. The resulting surface temperature can be
compared to the dew point temperature of indoor air to determine if
condensation will occur.

THERMAL BARRIER
• SERIES 9000 BF offers a thermally broken frame that substantially
improves the insulating value of the damper unit.
(Cooling of the frame and the internal duct work, which could lead to condensation,
will be greatly reduced when the damper is closed.)

Leakage testing was conducted in accordance with AMCA Standard 500-D-98. Holding torque
applied was 5.2 in.-lbs./sq. ft. on opposed blade dampers and 7 in.-lbs./sq. ft. on parallel
blade dampers AMCA Standard 500-D-98 states that air leakage is based on operation
between 50°F (10°C) and 104°F (40°C). All tests were performed with 120 lb-in resulting in a
maximum of 120 lb-in/ft² with the 12” x 12” damper.
The following sizes of TAMCO Series 9000 BF & 9000 ECT dampers were tested:
12" x 12" (305 mm x 305 mm), 24" x 24" (610 mm x 610 mm), 48" x 12" (1219 mm x 305 mm)

STRENGTH AND DURABILITY
•Aluminum dampers provide a prolonged and rust-free operational life over
galvanized steel types.
•Aluminum extrusions allow for intricate design features not possible with roll or
brake formed galvanized steel.
•Aluminum construction allows for additional strength by extruding
internal supports and thicker radii.
•Aluminum oxidizes to form a protective film. If the surface is
scratched, the film reforms.
(Standard damper is produced with a mill finish.)
M A I N T E N A N C E - F R E E
PERFORMANCE ACHIEVED
•Dampers are assembled using slip-proof linkage components that keep
blades aligned as per factory adjustment.
•Hexagon design feature of linkage and pivot elements allow for flat-on-flat
press fits that eliminate play and wear.
•Hard alloy aluminum (6005T5) linkage crank arm and pivot pin are doubly
secured by pincer-action and fastener.
•Large diameter (11/32" / 8.73mm) hard alloy aluminum (6005T5) linkage rod
connects the crank arms, which allows for a penetrating grip by the
cup-point fastener.
(Cup-point trunnion set screw creates a compression hard spot where it secures
to the linkage rod.)
•Trunnions are zinc-plated to provide a hard, smooth and
long-lasting rotating surface.
D E P E N D A B L E
"DUAL BEARING SYSTEM"
• TAMCO bearings consist of polycarbonate and acetal copolymer (Celcon) engineered thermal plastic resins.
• Dual bearing system is self-sealing, self-lubricating, and non-absorbent, which results in a totally
maintenance-free performance.
• Bearing materials meet or exceed tensile strength of 8,800 psi and flexural strength of 12,000 psi.
• Tensile impact strength of celcon is 70 ft.-lb./in.² and 145 ft.-lb./in.² for polycarbonate.
• TAMCO's bearing-to-bearing arrangement eliminates action between metal-to-metal and metal-to-plastic
riding surfaces. (Metal-on-metal steel, bronze or oil-lite bearings and metal-on-plastic nylon bearings have traditionally been
one of the weakest links in damper operation, requiring regular lubrication or eventual replacement.)
• TAMCO "Dual Bearing System" has a service life of 20 years plus.
(Replacement TAMCO bearings, which fit TAMCO dampers exclusively, have not been required in over 35 years, when dampers
have been installed according to manufacturer's guidelines.)

A N D
THERMAL BREAK DESIGN
•TAMCO’s Thermally Insulated Blade combines an aluminum shell, R-6.6 polyurethane foam and
three thermal breaks that result in a true insulation value of R-2.29.
(R-value of an internal insulation medium only, is not indicative of the true R-value of a blade as a whole and is
virtually negated if metal shell is not thermally broken.)
•Optimum placement of thermal breaks isolates the warm and cold sides, yet still maintains the
blade’s structural integrity.
•Insulating foam is intrinsic to the aluminum
blade extrusion and therefore shielded from the
airstream.
-109°F (-80°C)
Dry ice temperature
+ 70°F (+21°C)
Room air temperature
•Silicone side seals effectively resist providing a
path for the conduction of heat from one side
of the blade to the other.
T O T A L
T H E R M A L
PERFORMANCE
(Stainless steel or aluminum side seals create a
thermal bridge for conduction of heat.)
• TAMCO’s effective blade insulation is achieved
by controlling the forces of radiation,
convection, conduction and infiltration.
Thermal breaks are the key to providing real
insulation value.
DRY ICE TEST
(R-value of TAMCO’s insulated damper blade falls between
that of a double- and a triple-glazed thermal window.)
• TAMCO’s design and material matrix provides
for durable and dependable components.
• TAMCO’s exacting quality control and sound
workmanship ensure product integrity.
• TAMCO provides, or has available installation
guidelines, technical support and a toll-free
customer service number.
(Each and every TAMCO damper displays the 1-800
customer service number.)
• TAMCO products and personnel are your
guarantee of total thermal performance.
E X T R E M E L Y
LOW LEAKAGE RATE
• Extremely flexible extruded silicone side seals and peroxide cure
EPDM blade gaskets are supplied as standard.
(EPDM is a terpolymer of ethylene, propylene and a diene. Peroxide cure
helps to limit compression.)
• Leakage rate through a 48” x 48” (1219mm x 1219mm) TAMCO
Thermally Insulated Damper at 4” (1kPa) w.g. pressure differential
to be no greater than 4.125 cfm/sq.ft. (21 l/s/m²).
• Service temperature of the damper is 185°F (85°C) to -40°F
(-40°C) with a modest increase in the leakage rate as temperatures
decrease to -40°F (-40°C).
(See comparison graph in Severe Cold Testing section; also see Severe Cold
Upgrade Option.)
Thermograms, taken from the warm side, illustrate
the high heat loss to the chilling chamber of a noninsulated damper (darker image), versus the TAMCO
Thermally Insulated Damper (bright image).
• Silicone and EPDM provide outstanding dynamic
fatigue resistance that ensures sealing longevity,
plus excellent resistance to weathering,
compression set, and heat.
• Silicone and EPDM seals have an approximate
service life of 25 years.
(TAMCO side seals and blade gaskets eliminate
infiltration of air that could reduce or nullify the
effects of insulation.)

UPGRADE OPTION
•Upgrade option offers silicone side seals and blade gaskets,
replacing the standard TPE and EPDM components.
(Silicone combines features of silica, silicate minerals, and organic
compounds which result in an inertness towards deteriorating effects
of ozone, corona, weathering, and other forces, yet incorporates an
extraordinary flexibility.)
•Silicone is virtually unaffected by cold winter temperatures. Air
leakage tests performed in a cold chamber revealed that silicone
seals allowed only a minimal increase in the leakage rate from 40°F
(4°C) to -40°F (-40°C).
(See TAMCO Severe Cold Damper Testing graphs on the interior of this
brochure. Cold box testing revealed no discernible change in flexibility,
or compressibility of silicone between 70°F (21°C) and -40°F
(-40°C).)
•Silicone’s superior dynamic fatigue resistance ensures prolonged
sealing longevity, plus phenomenal resistance to weathering,
compression set, and heat.
(Even though general-purpose silicone can withstand 500°F (260°C),
the upper operating temperature of the damper unit, as a whole, is
185° F (85°C).)
•Silicone seals have an estimated service life of 30 years.

Leakage testing was conducted in accordance with AMCA Standard 500-D-98. Holding torque
applied was 5.2 in.-lbs./sq. ft. on opposed blade dampers and 7 in.-lbs./sq. ft. on parallel
blade dampers. AMCA Standard 500-D-98 states that air leakage is based on operation
between 50°F (10°C) and 104°F (40°C). All tests were performed with 120 lb-in resulting in a
maximum of 120 lb-in/ft² with the 12” x 12” damper.
The following sizes of TAMCO Series 9000, 9000 SC & 9000 SW dampers were tested:
12" x 12" (305 mm x 305 mm), 24" x 24" (610 mm x 610 mm), 48" x 12" (1219 mm x 305 mm)

• Thermally broken insulated blade damper was tested to provide a blade temperature
index of 55, which is analogous to both the condensation resistance factor (CRF) of AAMA
1502.7 Test Method for Condensation Resistance of Windows, Doors and Galvanized Wall
Sections and the Window Temperature Index, I, used to specify window condensation
resistance under CAN/CSA-A440-M90 Windows, A National Standard of Canada.
• Temperature Index = [Tsi - To] / [Ti - To] x 100 = 55. This equation can be used to calculate
the surface temperature for any combination of inside and outside air temperatures. The
resulting surface temperature can be compared to the dew point temperature of indoor air
to determine if condensation will occur.
(Condensation is a function of the damper surface temperature, the inside environment temperature
and the inside humidity levels. The inside surface temperature is affected by the amount of heat loss
through the blade (see temperature index number), and outside cold air infiltration.)
• An effective thermal break keeps the inside surfaces warmer. This permits a higher
indoor humidity without causing condensation. When condensation does occur, in cases
of very high humidity, it is significantly reduced and this inhibits icing to colder outdoor
temperatures.
• Aluminum components, foam insulation and sealing gaskets are not affected by moisture.

The table (above) and the chart (below) are used to find the pressure drop through all TAMCO Thermally Insulated Dampers.
1) In the above table, select the area factor value recorded, where the duct width column and duct height line meet.
2) In the chart below, enter the area factor obtained from above and the cfm for the application and read the pressure drop off where the “Area Factor” line and the “Volume
Flow Rate” column meet. (Example: duct size 20”w x 32”h = .32 area factor, (above table). Then, if cfm is 2000, pressure drop = .012” w.g. (chart below).

Note: 1. Ratings are based on AMCA Standard 500, using Test Setup Apparatus Figure 5.3 (damper installed with duct upstream & downstream).
2. Above Area Factor values are based on flanged-to-duct type installations. Pressure drop will be greater for installed in-duct type dampers. Call TAMCO Customer Service at
1-800-561-3449 for pressure drop calculations for installed in-duct type dampers.
3. Dampers sized for duct openings exceeding 37½” (953 mm) in height are equipped with a stiffener bar at mid-height, which is reflected in the above chart.

STRENGTH AND DURABILITY
•Aluminum dampers provide a prolonged and rust-free operational life over
galvanized steel types.
•Aluminum extrusions allow for intricate design features not possible with roll or
brake formed galvanized steel.
•Aluminum construction allows for additional strength by extruding
internal supports and thicker radii.
•Aluminum oxidizes to form a protective film. If the surface is
scratched, the film reforms.
(Standard damper is produced with a mill finish.)
M A I N T E N A N C E - F R E E
PERFORMANCE ACHIEVED
•Dampers are assembled using slip-proof linkage components that keep
blades aligned as per factory adjustment.
•Hexagon design feature of linkage and pivot elements allow for flat-on-flat
press fits that eliminate play and wear.
•Hard alloy aluminum (6005T5) linkage crank arm and pivot pin are doubly
secured by pincer-action and fastener.
•Large diameter (11/32" / 8.73mm) hard alloy aluminum (6005T5) linkage rod
connects the crank arms, which allows for a penetrating grip by the
cup-point fastener.
(Cup-point trunnion set screw creates a compression hard spot where it secures
to the linkage rod.)
•Trunnions are zinc-plated to provide a hard, smooth and
long-lasting rotating surface.

BLADE AND FRAME SEALS
• Silicone blade and frame seals outperform all other existing seals due to flexibility and durability.
(Silicone seals have an estimated service life of 30 years.)
• Silicone seals are virtually unaffected by cold operating temperatures. Air leakage tests undertaken in a cold chamber revealed that silicone seals allowed only a
minimal increase in leakage rates between 40ºF (4ºC) and -40ºF (-40º C).
• Silicone’s superior dynamic fatigue resistance ensures prolonged sealing longevity, plus phenomenal resistance to weathering, compression set, and heat.
(Even though general purpose silicone can withstand 500ºF (260ºC), the upper operating temperature of the damper unit as a whole is 212ºF (100ºC).)
D E P E N D A B L E
"DUAL BEARING SYSTEM"
• TAMCO bearings consist of polycarbonate and acetal copolymer (Celcon) engineered thermal plastic resins.
• Dual bearing system is self-sealing, self-lubricating, and non-absorbent, which results in a totally
maintenance-free performance.
• Bearing materials meet or exceed tensile strength of 8,800 psi and flexural strength of 12,000 psi.
• Tensile impact strength of celcon is 70 ft.-lb./in.² and 145 ft.-lb./in.² for polycarbonate.
• TAMCO's bearing-to-bearing arrangement eliminates action between metal-to-metal and metal-to-plastic
riding surfaces. (Metal-on-metal steel, bronze or oil-lite bearings and metal-on-plastic nylon bearings have traditionally been
one of the weakest links in damper operation, requiring regular lubrication or eventual replacement.)
• TAMCO "Dual Bearing System" has a service life of 20 years plus.
(Replacement TAMCO bearings, which fit TAMCO dampers exclusively, have not been required in over 35 years, when dampers
have been installed according to manufacturer's guidelines.)

SALT WATER SPRAY TESTING
• The TAMCO Series 1500 SW, a Brand X stainless steel damper and a Brand Y galvanized damper were exposed to 1000 hours of testing in a Singleton salt spray cabinet.
• Base torque readings were taken before testing. Changes in opening and closing torque readings were recorded as testing progressed.
• Samples were evaluated for changes in surface finishes and degree of rusting.
• The TAMCO Series 1500 SW damper's opening and closing torques were unchanged after 1000 hours of salt water spray testing.
• The surface of the Series 1500 SW damper showed no change other than a small accumulation of salt residue, which was easily wiped off with a damp cloth.
• Results for the appearance and change in torque requirements for the stainless steel and galvanized dampers are shown below.

ENHANCED AIR-FOIL DAMPERS
T.A. Morrison & Co. Inc. certifies that the TAMCO Series 1500 & 1500 SW Enhanced Air-Foil
Control Damper shown herein are licensed to bear the AMCA Seal. The ratings shown are
based on tests and procedures performed in accordance with AMCA Publication 511 and
comply with the requirements of the AMCA Certified Ratings Program. The AMCA Certified
Ratings Seal applies to air performance ratings and air leakage ratings.
Leakage testing was conducted in accordance with AMCA Standard 500-D-98. Holding torque
applied was 5.2 in.-lbs./sq. ft. AMCA Standard 500-D-98 states that air leakage is based on
operation between 50°F (10°C) and 104°F (40°C). All tests were performed with 120 lb-in
resulting in a maximum of 120 lb-in/ft² with the 12” x 12” damper.
The following sizes of TAMCO Series 1500 dampers were tested:
12" x 12" (305 mm x 305 mm), 24" x 24" (610 mm x 610 mm), 48" x 12" (1219 mm x 305 mm)

LOW LEAKAGE / MAINTENANCE-FREE
AIR-FOIL CONTROL DAMPER
A L U M I N U M
STRENGTH AND DURABILITY
•Aluminum dampers provide a prolonged and rust-free operational life over
galvanized steel types.
•Aluminum extrusions allow for intricate design features not possible with roll or
brake formed galvanized steel.
•Aluminum construction allows for additional strength by extruding
internal supports and thicker radii.
•Aluminum oxidizes to form a protective film. If the surface is
scratched, the film reforms.
(Standard damper is produced with a mill finish.)
M A I N T E N A N C E - F R E E
PERFORMANCE ACHIEVED
•Dampers are assembled using slip-proof linkage components that keep
blades aligned as per factory adjustment.
•Hexagon design feature of linkage and pivot elements allow for flat-on-flat
press fits that eliminate play and wear.
•Hard alloy aluminum (6005T5) linkage crank arm and pivot pin are doubly
secured by pincer-action and fastener.
•Large diameter (11/32" / 8.73mm) hard alloy aluminum (6005T5) linkage rod
connects the crank arms, which allows for a penetrating grip by the
cup-point fastener.
(Cup-point trunnion set screw creates a compression hard spot where it secures
to the linkage rod.)
•Trunnions are zinc-plated to provide a hard, smooth and
long-lasting rotating surface.
D E P E N D A B L E
"DUAL BEARING SYSTEM"
• TAMCO bearings consist of polycarbonate and acetal copolymer (Celcon) engineered thermal plastic resins.
• Dual bearing system is self-sealing, self-lubricating, and non-absorbent, which results in a totally
maintenance-free performance.
• Bearing materials meet or exceed tensile strength of 8,800 psi and flexural strength of 12,000 psi.
• Tensile impact strength of celcon is 70 ft.-lb./in.² and 145 ft.-lb./in.² for polycarbonate.
• TAMCO's bearing-to-bearing arrangement eliminates action between metal-to-metal and metal-to-plastic
riding surfaces. (Metal-on-metal steel, bronze or oil-lite bearings and metal-on-plastic nylon bearings have traditionally been
one of the weakest links in damper operation, requiring regular lubrication or eventual replacement.)
• TAMCO "Dual Bearing System" has a service life of 20 years plus.
(Replacement TAMCO bearings, which fit TAMCO dampers exclusively, have not been required in over 35 years, when dampers
have been installed according to manufacturer's guidelines.)

Leakage testing was conducted in accordance with AMCA Standard 500-D-98. Holding torque
applied was 5.2 in.-lbs./sq. ft. on opposed blade dampers and 7 in.-lbs./sq. ft. on parallel
blade dampers AMCA Standard 500-D-98 states that air leakage is based on operation
between 50°F (10°C) and 104°F (40°C). All tests were performed with 120 in.-lbs. in resulting
in a maximum of 120 in.-lbs./ft² with the 12” x 12” damper.
The following sizes of TAMCO Series 1000 & 1000 SW dampers were tested:
12" x 12" (305 mm x 305 mm), 24" x 24" (610 mm x 610 mm), 48" x 12" (1219 mm x 305 mm)

The table (above) and the chart (below) are used to find the pressure drop through all TAMCO Series 1500, 1500 SW, 1000 & 1000 SW Air-Foil Control Dampers.
1) In the above table, select the area factor value recorded, where the duct width column and duct height line meet.
2) In the chart below, enter the area factor obtained from above and the cfm for the application and read the pressure drop off where the
“Area Factor” line and the “Volume Flow Rate” column meet.
(Example: duct size 16”w x 36”h = .20 area factor (above table). Then, if cfm is 2000, pressure drop = .008” w.g. (chart below).)

Note: 1. Ratings are based on AMCA Standard 500, using Test Setup Apparatus Figure 5.3 (damper installed with duct upstream & downstream).
2. Above Area Factor values are based on flanged-to-duct type installations. Pressure drop will be greater for installed in-duct type dampers. Call TAMCO Customer Service at
1-800-561-3449 for pressure drop calculations for installed in-duct type dampers.
3. Dampers sized for duct openings exceeding 37½” (953 mm) in height are equipped with a stiffener bar at mid-height, which is reflected in the above chart.

Duct" type for sizes under 9 ft.² (.83m2).
• Dampers sized for duct openings exceeding
37½" (953mm) in height are equipped with
a stiffener bar at mid-height, to strengthen
and maintain air leakage tolerances.

STRENGTH AND DURABILITY
•Aluminum dampers provide a prolonged and rust-free operational life over
galvanized steel types.
•Aluminum extrusions allow for intricate design features not possible with roll or
brake formed galvanized steel.
•Aluminum construction allows for additional strength by extruding
internal supports and thicker radii.
•Aluminum oxidizes to form a protective film. If the surface is
scratched, the film reforms.
(Standard damper is produced with a mill finish.)
M A I N T E N A N C E - F R E E
PERFORMANCE ACHIEVED
•Dampers are assembled using slip-proof linkage components that keep
blades aligned as per factory adjustment.
•Hexagon design feature of linkage and pivot elements allow for flat-on-flat
press fits that eliminate play and wear.
•Hard alloy aluminum (6005T5) linkage crank arm and pivot pin are doubly
secured by pincer-action and fastener.
•Large diameter (11/32" / 8.73mm) hard alloy aluminum (6005T5) linkage rod
connects the crank arms, which allows for a penetrating grip by the
cup-point fastener.
(Cup-point trunnion set screw creates a compression hard spot where it secures
to the linkage rod.)
•Trunnions are zinc-plated to provide a hard, smooth and
long-lasting rotating surface.
S P A C E - S A V I N G
NARROWER PROFILE
• Dampers are constructed with 4” blades.
• When damper blades are in the fully open position, blades do not exceed
beyond the 4” frame.
D E P E N D A B L E
"DUAL BEARING SYSTEM"
• TAMCO bearings consist of polycarbonate and acetal copolymer (Celcon) engineered thermal plastic resins.
• Dual bearing system is self-sealing, self-lubricating, and non-absorbent, which results in a totally
maintenance-free performance.
• Bearing materials meet or exceed tensile strength of 8,800 psi and flexural strength of 12,000 psi.
• Tensile impact strength of celcon is 70 ft.-lb./in.² and 145 ft.-lb./in.² for polycarbonate.
• TAMCO's bearing-to-bearing arrangement eliminates action between metal-to-metal and metal-to-plastic
riding surfaces. (Metal-on-metal steel, bronze or oil-lite bearings and metal-on-plastic nylon bearings have traditionally been
one of the weakest links in damper operation, requiring regular lubrication or eventual replacement.)
• TAMCO "Dual Bearing System" has a service life of 20 years plus.
(Replacement TAMCO bearings, which fit TAMCO dampers exclusively, have not been required in over 35 years, when dampers
have been installed according to manufacturer's guidelines.)

LOW LEAKAGE / LONG-TERM, DEPENDABLE
BACK DRAFT DAMPERS
A L U M I N U M
STRENGTH AND DURABILITY
•Aluminum dampers provide a prolonged and rust-free operational life over
galvanized steel types.
•Aluminum extrusions allow for intricate design features not possible with roll or
brake formed galvanized steel.
•Aluminum construction allows for additional strength by extruding
internal supports and thicker radii.
•Aluminum oxidizes to form a protective film. If the surface is
scratched, the film reforms.
(Standard damper is produced with a mill finish.)
M A I N T E N A N C E - F R E E
PERFORMANCE ACHIEVED
•Dampers are assembled using slip-proof linkage components that keep
blades aligned as per factory adjustment.
•Hard alloy aluminum (6005T6) linkage crank arm and pivot pin are
doubly secured by pincer-action and fastener.
•Large diameter (11/32" / 8.73mm) hard alloy aluminum (6005-T6C) linkage
rod connects the crank arms, which allows for a penetrating grip by the
cup-point fastener.
(Cup-point trunnion set screw creates a compression hard spot where it secures to
the linkage rod.)
•Trunnions are zinc-plated to provide a hard, smooth and
long-lasting rotating surface.
• Series 7000 Back Draft Dampers
allow operation in vertical and
horizontal-up positions.
L O W
LEAKAGE RATE
• Damper is supplied with extruded silicone blade and side seals.
• Leakage through a 24” x 24” (610 mm x 610 mm) TAMCO Back Draft Damper at 1” (.25 kPa) w.g. pressure difference to be not
greater than 20 cfm/ft.² (101.2 l/s/m2).
• Service temperature of the damper is 212°F (100°C) to -40°F (-40°C).
• Silicone’s superior dynamic fatigue resistance ensures prolonged sealing longevity, plus phenomenal resistance to
weathering, compression set, and heat.
• Silicone seals have an approximate service life of 30 years.
D
E P E N D A B L E
"LINKAGE SYSTEM"
• Linkage system consists of hard alloy aluminum (6005-T6C) crank arms fastened to zinc-plated steel pivot rods and is
doubly secured within a channel running along the top of the blade.
• Bearing system is composed of Celcon bearings rotating on zinc-plated, ½” steel pivot points.
• Celcon bearings are self-sealing, self-lubricating, and non-absorbent, which results in a totally
maintenance-free performance.
• Bearing materials meet or exceed tensile strength of 8,800 psi and flexural strength of 12,000 psi.
• Tensile impact strength of Celcon is 70 ft.-lb./in.² and 145 ft.-lb./in.² for polycarbonate.
• TAMCO's linkage system eliminates action between metal-to-metal riding surfaces. (Metal-on-metal steel, bronze and oil-lite
bearings have traditionally been one of the weakest links in damper operation, requiring regular lubrication or eventual replacement.)

• Brackets are slotted to allow precision slide adjustment of the weights.
• Series 7000 WT Weighted Back Draft Dampers allow operation in vertical
and horizontal-up positions.
• Brackets are affixed to blades using ¼-20 x 3/8” socket head cap
screws with cup-points.
• Series 7000 CW Counterweighted Back Draft Dampers allow
operation in vertical, horizontal-up and horizontal-down positions.

STRENGTH AND DURABILITY
• Aluminum insect screens and frames provide a prolonged and rust-free
operational life over galvanized steel types.
• Aluminum oxidizes to form a protective film. If the surface is scratched,
the film reforms.
(Standard insect screen is produced with a mill finish.)
S
I
L

C
O
N
E
FRAME SEALS
• Silicone frame seals outperform all other existing seals due to
flexibility and durability.
(Silicone seals have an estimated service life of 30 years.)
• Silicone seals are virtually unaffected by cold operating temperatures.
• Silicone’s superior dynamic fatigue resistance ensures phenomenal
resistance to weathering, compression set, and heat.
F A C E
O R
S I D E
R E M O VA B L E
• Tamco Insect Screens are designed to be removed from frame easily, to
facilitate cleaning.
• Face removable screens are easily lifted out of the front of the frame,
using nylon finger pulls.
• Side removable insect screens are designed for installations where front
removal is not possible. The screen slides out from the side of the frame
using the pull handle.
53
I D E A L
SOLUTION
• Tamco Insect Screens are the ideal solution for preventing foreign
particles from entering filtration systems.
• Insect screens are perfect for fresh air intake applications in areas with
high density insect populations and in areas prone to small, air-borne
debris accumulation.

BEFORE INSTALLATION
• Before installing, inspect damper for possible damage caused in shipping.
• If minor damage has occurred to frame corners or flanges, correct by bending
or hammering back into position. Ensure correct realignment of repair, as bent
or twisted frames might not mate with mounting angles, or additional damper
sections, properly.
• Do not install damper if damage is more than superficial, if uncertain as to
extent of damage, or if damper does not seal correctly.
Call TAMCO customer service at 1-800-561-3449.
• Operate damper section manually (on a flat section of floor) to verify correct
blade action and sealing.
(A) To correctly verify sealing action, loosen hex nuts of U-bolt located on drive blade.
Extend steel drive rod to maximum of 9” past frame. Re-tighten hex nuts on U-bolt.
(B) Using drive rod, slowly apply closing torque, while ensuring that damper frame does
not twist due to torque being applied. (Larger dampers may require additional
person to hold damper frame square and true.)
(C) If possible, use daylight or inside light source as a backdrop to verification procedure.
No light should be visible through damper.
CAUTION SHOULD BE EXERCISED TO ENSURE FINGERS ARE NOT IN
WAY OF MOVING LINKAGE PARTS OR BLADES.

DAMPER TYPES
“INSTALLED IN DUCT” TYPE
Linkage Must Be Accessible
After Installation
• Damper must be installed square.
• Damper approximately 1/2” smaller than specified duct size.
• Ensure that duct is square and/or large enough to allow damper to be installed square.
• Make hole in duct work, if required, to allow extension of drive rod.
• Bottom of frame must sit flat on floor of duct to prevent twisting, sagging, or bumping up, as
this could cause leakage between bottom frame and bottom blade.
• Verify that damper is square and then secure bottom frame to floor of duct using a 90°
mounting angle. Operate damper manually to confirm proper sealing.
• As each mounting angle is installed, verify operation to ensure damper is sealing correctly.
• Caulk all joints.
“FLANGED TO DUCT” TYPE
• Damper must be installed square.
• Damper flange is 1” larger than duct all around.
• Do not assume that duct is square. Verify that duct flange is
square, flat and even.
• Verify that damper is square. Operate damper to verify free
movement of blades and correct sealing. Secure damper.
Re-verify that damper is square.
• Repeat procedure for other flange, if ducted on both sides.
• Caulk all joints.

FOR MULTI-SECTION DAMPERS
REQUIREMENTS:
�
�
• Intermediate structural support is required to resist applied pressure loads for dampers that consist of two or more sections in both height and width. (See below.)
• Tubular steel structural support may be required for large multi-sectioned dampers.
�
�
MAXIMUM DEFLECTION:
• The structure providing intermediate support must be designed to resist the highest pressure load, with deflection of less than L/230. This applies whether the pressure load is created by the mechanical system, or by wind load, or if the damper is mounted on the exterior of the building.
Intermediate structural support required.
DESIGN OF STRUCTURAL SUPPORT FOR TAMCO DAMPERS
Example:
Design the structural support required to carry TAMCO dampers at the 17th story of a
building in Ottawa, Ontario, Canada. (Assuming that the maximum internal pressure, as a
result of the mechanical systems, is 2 inches of water, 10.4 psf or 500 Pa.)
Analysis:
=
Net wind pressure
on damper
+
exterior pressure
or suction
interior pressure in the mechanical plenum
(as specified by the mechanical engineer)
p = qCeCgCp external + 10.4 psf
1997 OCB 4.1.8
Where: p = the specific external pressure acting statically and in a direction normal
to the surface, either as a pressure directed towards the surface or as a
suction directed away from the surface.
q = the reference velocity pressure based on a 1 in 30 probability of being
exceeded in any one year for design of structural members for strength.
q1/30 = 7.72 psf (0.37 kPa in Ottawa, Ontario).
Ce = exposure factor based on the height of the building (1.4 for a 170 ft.
high building).
Cg =gust factor (2.5 for cladding elements and small structural components).
Cp = external pressure coefficient (1.0 for high local suction).
p = qCeCgCp external + 10.4 psf
p = 7.72 psf (1.4) (2.5) (1.0) + 10.4 psf
p = 37.4 psf
Total net factored pressure:
pf = 1.5 (live wind load)
pf = 1.5 • (37.4)
pf = 56.1 psf
(2.7 kPa)
Factored distributed load over vertical support framing member:
wf = 56.1 psf (5')
wf = 281 lb./ft.
Factored maximum moment:
Mf = wf l²/8
Mf = 281 • (10)²/8
Mf = 3513 lb./ft.
73
Assumptions:
The subject building is 17 floors high and has plan dimension of 120' by 120' (36.6m by
36.6m). The dampers will be mounted on vertical framing members spanning from the 17th
floor to the roof slab level.
Resisting moment:
Mr has to be equal to or greater than Mf for an unsupported length of 10' (3.05m)
Acceptable vertical support member:
C4 x 6.0 - 4" structural steel channel
(metric designation C100 x 9)
Mr = 3980 lb.ft. for an unsupported length (Lu) = 13'.
(Mr = 5.4 kNm at Lu = 4m)
Check deflection criteria:
Maximum allowable deflection is L/320 = 10'/320 = 0.375" (9.5mm)
Maximum deflection at mid-height of the channel:
∆ = 5 w l4
384 E I
For deflection, the reference velocity pressure, q, is based on a 1 in 10 probability of
being exceeded in any one year. q1/10 = 6.27 psf (0.30 kPa in Ottawa, Ontario).
p = qCeCgCp external + 10.4 psf
p = 6.27 psf (1.4) (2.5) (1.0) + 10.4 psf
p = 32.3 psf
w = 32.3 psf (5')
w = 162 lb./ft.
5 (162 lb./ft.) (10')4
384 (29,000 ksi) (4.25 in4 )
∆=
∆=
5 (13.5 lb./ft.) (120")4 = 0.30
384 (29•106 psi) (4.25 in4 )
(7.6mm)
Therefore, an acceptable vertical support member for this example is a C4 x 6.0.

TROUBLESHOOTING
(A)
• If light lines are present across full length of blade, check that closing torque being applied is neither too little nor
too much.
• Under-rotation will not let blade gaskets compress, whereas over-rotation can cause blades to re-separate.
(B)
• If light lines are observed only along half of blade length, square up position of top frame member, relative to
bottom frame, by pivoting top frame member either in or out.
• A small movement in one of two directions could seal light lines by taking out distortion to frame caused by torque
being applied to an unsecured damper.
(C)
• If light lines are observed between side frame members and blade ends of a damper, especially near center line,
verify measurement across damper at top, center, and bottom.
• If measurement should vary by more than 1/16”, readjust side mounting angles to bring side frame members to
correct dimension, thus matching top and bottom dimensions.
• If light lines disappear, ensure that these matching dimensions are retained when fastening mounting angles during
installation.
(D)
• If light lines appear only near top and bottom, on opposite sides of damper, between side frame members and blade
ends of a damper, verify square position with tape measure and adjust if required.
• Move top frame member either left or right to square up damper. Light lines should disappear.
(E)
• If damper is hard to operate by hand, verify that frame sides are not squeezed in or twisted.
• This could have the effect of increasing required torque or binding pivot action.
• In either case, bearing life could be sharply reduced.
• Verify that frame sides are parallel by measuring across damper at the top, center and bottom.
• Also verify that dimensions on both sides of damper are equal.
(F)
• If light appears only between last blade and top or bottom of damper frame, it may be due to top or bottom frame
member being distorted (twisted) when fastened to duct work.
• Ensure that top or bottom frame members are not distorted by loosening fasteners and shimming frame, if required.

FLOW CONTROL DAMPERS
Figure 1
Characteristic Curve for Parallel Blade Dampers
For two-position or shut-off applications, where dampers
are always either fully open or fully closed, flow control
characteristics are largely irrelevant. Shut-off dampers
should be selected and sized to minimize pressure
drop in the full open position, and to minimize air
leakage and maximize thermal performance in the
closed position. TAMCO Dampers are ideal in these
applications.
Figure 2

% Flow
For applications where dampers are used to control
flow over a range of air flows, it is necessary to size the
dampers based on the pressure drop of the damper in
different positions, the resistance of the duct’s system that
the damper affects, and the characteristics of the control
signal. The interactions between a flow control damper,
the system in which it is installed, and the controls can
be complex. It is critical for proper control and efficient
system operation, that known and controllable factors be
optimized. To this end, most control system manufacturers
have developed sizing guidelines. We recommend
that the detailed sizing procedures provided
by control manufacturers and ASHRAE, be
used for sizing dampers, especially in complex
or critical applications. The following sections
provide information on the characteristics of TAMCO
dampers to be used in these design methods and also
provides some further general sizing guidelines that may
be appropriate in simple systems.

70tested to AMCA Standard 500-89
at blade angles of 15, 30, 45, 60, 75 and 90 degrees.

The results confirmed 60
that the performance characteristics
(linearity curves) of TAMCO Series 1000, 1500, and 9000
50 to the assumptions used by major
dampers are comparable

GENERAL SIZING GUIDELINES
Even for general sizing guidelines, one must understand the term
"Damper Authority", which is defined as the following ratio:
pressure drop across a control damper in
the full open position
total pressure drop of the portion of
the system that the damper controls.
The characteristic curves shown in Figures 1 and 2 correspond to the
100% authority curve, where the entire pressure drop of the system
occurs across the damper. As can be seen, this curve is not linear. As
Damper Authority decreases (system pressure drop excluding the damper
goes up), the shape of the flow versus blade angle curve changes. A
family of curves can be plotted as in Figures 3 and 4, showing damper
performance at various values of Damper Authority.

In most, but not all, flow control applications, a linear performance is
desired. Proper sizing of the damper will result in economical damper
selections, with performance close to linear. System characteristics, as
well as damper characteristics, must be addressed.

an arbitrary damper size, often the full dimension of the duct, determines

pressure drop across the damper at full flow from manufacturer selection
charts, and does a “check calculation” for damper authority. If the result
indicates that the damper authority is insufficient for the application, smaller dampers are selected until required authority is achieved.

The second method consists of calculating the desired pressure drop across the damper at full flow, using the appropriate authority values
and calculated duct system pressure losses. The procedure is:
• Calculate the duct system pressure loss at full flow, excluding the control damper loss, which is still unknown.
• Select the damper authority required to provide the desired control characteristics.
• Calculate the control damper pressure loss at full flow:
PD = (DA / (100 - DA) x PS where PD = damper pressure drop at full flow / DA = damper authority, selected by designer / PS = duct system pressure loss, calculated using standard methods.
• Select damper sizes from the calculated required pressure drop, PD, and manufacturer’s selection charts.
When air flow must be controlled in direct proportion to a control signal,

is desirable.

MIXED-AIR CONTROL
A typical application is the economizer section in an air handling system,
where two air streams are mixed to maintain a fixed temperature set point.
To achieve stable and predictable static pressures and improved energy
efficiency and comfort, the dampers should be sized so that the total flow
rate of the system remains constant. This is generally best achieved by
selecting dampers that are sized to provide linear performance in the
range of interest. For dampers in ducted systems, this usually requires that
the outside air, return air, and exhaust dampers all be selected with similar
authority, in the order of 8% to 10% for opposed blade dampers, or 20%
to 25% for parallel blade dampers. However, in many cases, the outside
air damper is installed behind the intake louver and is the same size as the
louver in an effort to reduce entry of snow and rain. This results in grossly
oversized dampers. In this case, size the outside and exhaust dampers
with the same authority. Opinions differ on sizing the return damper in this
situation. A general guideline would be to select a parallel blade damper
with a pressure drop similar to the pressure difference between the inlet
and exhaust ducts at the return duct takeoff. The outside and exhaust
dampers should be of the opposed blade type.
FACE & BYPASS CONTROL
For face and bypass applications, the pressure drop through both sections
should be the same. Size the bypass damper so that the pressure drop is
the total of coil plus coil damper pressure drops.
PRESSURE CONTROL
This application is no longer common since the advent of cost-effective
variable-speed drives and fan inlet vanes. Both are more energy efficient
and should be considered over damper control for these applications.

Noise Criteria (NC) ratings were determined by subtracting 10dB (room effect) from the Sound Power Levels.
When comparing NC numbers with those supplied by other damper manufacturers, ensure that only 10dB for room effect has
been subtracted. Further subtraction of another 10dB for room attenuation will result in false field readings.
Noise Criteria Ratings
NC ratings published above for use with NC curves (ASHRAE 1993 Fundamentals
Handbook: Chapter 7). NC curves define limits that octave-band spectrum of a noise source
must not exceed to achieve a level of occupant acceptance.
ROOM Criteria Ratings

TAMCO SUCCESS STORIES
RICHARD J. DALEY CENTER
Mr. Dan Romero, Chief Engineer at the Richard J. Daley Center, Chicago,
headed the project to retrofit one of the key systems in this building. The primary
requirement was to find a low-leakage, maintenance-free damper product that
could withstand 9 inches of static pressure.
A meeting between Stern Mechanical, Mr. Romero and Mr. Jim Karambelas was
instrumental in developing a plan for TAMCO to supply more than 2,700 square
feet of dampers for this job. The damper selected was the Series 1500 (AMCA
certified at 1.7 cfm/sq.ft. at 1 inch of
static pressure). The application also
called for the use of specially designed,
TAMCO horizontal and vertical jackshafts. Pneumatic actuators were used
in a tandem position, as shown in the
picture on the right.
MB Real Estate was so pleased with
TAMCO’s product and service that they
are proceeding with replacing existing
dampers with TAMCO dampers for the
rest of this project.
ONE NORTH WACKER DRIVE
The TAMCO Series 1500 was specified for this entire
project. The contract was secured as a result of the solid
representation of TAMCO’s innovative dampers solutions
by E.I.P. to E.S.D. Engineering. Johnson Controls purchased
more than 3,100 square feet of TAMCO’s dampers, to
install at One North Wacker Drive, Chicago.
F. E. Moran was the mechanical contractor on this project.
Mr. Ed Walsh, Chief Engineer at the John Buck Company
(general contractor), was very impressed with the quality
of the product and service obtained from both E.I.P. and
TAMCO.
“...TAMCO dampers have been
installed at the university for over
two and half years and have not
needed any maintenance, and they
still perform like new!”
TAMCO GOES TO SCHOOL
Indiana University & Purdue University Indianapolis
(IUPUI) chose TAMCO dampers to replace all of the existing
dampers in the Business Spea Building, in Cavanaugh Hall
and in the University Library. In total, over 600 square feet
of TAMCO Series 9000 Thermally Insulated Dampers,
Series 9000 SC Severe Cold Option Dampers and Series
1500 Ultra-low Leakage Dampers were installed. TAMCO
dampers were used to replace old dampers that had failed
due to freeze-up and wear over the years.
This project was secured by Keller-Rivest, the exclusive
distributor for TAMCO products in Indiana. Mr. Frank
Haag, of Keller-Rivest, met with the engineering staff at
IUPUI. He offered the university a free damper which
was used as a replacement on an air handling unit. The
engineers were extremely impressed with the performance
of the TAMCO damper. Following this initial testing, the
engineers presented the TAMCO damper to the University
architects, who approved the dampers and have listed
TAMCO as standard in their specifications ever since.
Mr. David Pfeifer (Energy Systems Project Manager Campus Facility Services) stated that the TAMCO insulated
dampers were installed in all outside air applications, because
they are the optimal solution in cold winter conditions. “They
have good insulation value and good weather seals...they
protect coils against freeze-up.” IUPUI selected Series 1500
dampers for all their return and exhaust air applications.
Their ultra-low leakage rate makes them ideally suited to
these applications, while providing a means of cost control
on a damper replacement project of this size.
Mr. Pfeifer indicates that one of the key selling features of
TAMCO dampers is “...they came straight from the factory
more square than those of other damper manufacturers.”
Mr. Pfeifer also lists the robust jack shafts and weathertight seals as other selling points. “We have used all
of the accessories and have been impressed with their
performance.”
IUPUI has found that the installation of TAMCO
dampers is easier, because of the one-inch wide flanges
which provide a flat surface to insert screws. They also
preferred TAMCO dampers because “Z” plates are provided
with all multi-section dampers and holes are pre-drilled for
jack shafts.
The engineers and project managers at IUPUI have been
very impressed with the reliability of TAMCO dampers. Mr.
Pfeifer says, “The TAMCO dampers have been installed
at the university for over two and half years and have not
needed any maintenance, and they still perform like new!
The university has replaced three buildings completely with
TAMCO dampers and three new buildings will have TAMCO
dampers in all the air handlers when we finish.”
