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.) 3 TAMCO ... the only proven maintenance-free dampers on the market. THERMAL INSULATING FEATURES & BENEFITS Thermal breaks are the key to providing real insulation value. A D V A N C E D I N S U L A T I N G A N D 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. -109°F (-80°C) Dry ice temperature 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.

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. E N H A N C E D CONDENSATION RESISTANCE temperature of the air to which it is exposed. Relatively small changes in temperature can make a significant difference in what indoor humidity can be sustained without condensation.) and outside air temperature (To), and the difference between the inside air temperature (Ti) and outside air temperature.) (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.) Comparison of condensation resistance performance of thermally broken insulated blade versus non-thermally broken insulated blade and standard air foil blade. 68°F 20ºC 100 64°F 18ºC S U R FA C E T E M P E R AT U R E • 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.

E 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.) 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). 5 • Polyurethane resin isolates the warm and cold sides, yet still maintains the structural integrity of the frame. • Resin pockets, being flush with interior of frame, do not impede airflow, or reduce free area through the damper. • Available only as “Flanged to Duct” mounting type. EXTREME COLD TEMPERATURE UPGRADE OPTION E X T R E M E C O L D S E R I E S 9 0 0 0 E C T T E M P E R AT U R E UPGRADE OPTION • The SERIES 9000 ECT upgrade option is specifically designed for extreme cold temperatures below -40°F (-40°C), down to -100°F (-73°C). • Formula for ECT silicone seals is the same as that used by NASA for its Aerospace program.

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.) 11 TAMCO ... the first manufacturer to offer a thermally insulated line of products. THERMAL INSULATING FEATURES & BENEFITS A D V A N C E D I N S U L A T I N G 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.)

S E V E R E C O L D 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.

CONDENSATION (ICE) -11°F -24°C www.tamco.ca • 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.

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 I L I C O N E 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.) 21 U LT R A L O W L E A K A G E / S I L I C O N E S E A L S S A L T WAT E R R E S I S TA N C E S E R I E S 1 5 0 0 S W Applications: Type 316 Stainless steel frame assembly screws Silicone side seals • Ideally suited for coastal climates. • Recommended for inland applications, where tire spray from winter-salted roads has been known to corrode dampers installed in close proximity to roads or highways.

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.

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.) 27 Note that all technical information available on TAMCO’s web site at www.tamco.ca supersedes and takes precedence over all information contained within this catalogue.

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.) 33 FREE AREA CHARTS SERIES 1400 & 1400 SW F E E T S Q U A R E D HEIGHT (inches) FLANGED TO DUCT 12 24 36 48 M E T E R S S Q U A R E D HEIGHT (mm) 60 305 610 915 1220 PERCENTAGE NOTE: • To reduce pressure drop, use "Flanged to Duct" type for sizes under 9 ft.² (.83m2).

If the surface is scratched, the film reforms. (Standard insect screen is produced with a mill finish.) S I L I 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.

FRONT / TOP END UP / RIGHT HAND •When labels on blades are viewed right side up, the damper orientation is Front/Top end up. •When viewed as Front/Top end up, right hand (RH) has drive rod as shown. Left hand (LH) has drive rod on left. •The damper, as a complete unit, can be installed right side up, upside down, standing up, or lying flat. •There is no specified air entry or air exhaust side. •Ensure that damper is installed allowing for future access to side linkage, as well as damper jumper bracket, or jack shaft, if so supplied. •Z-plates and fasteners, provided by TAMCO to interconnect damper sections, are for alignment purposes only and may not be considered as structural supports. •Duct work construction and bracing must be sufficient to support damper. Do not use damper to square up duct. System must support damper. Damper cannot support system. •For vertical applications, the damper must be installed so that linkage faces upward. Vertically installed sections must be properly braced and supported. •A 12"-long, hexagonal steel drive rod is provided as standard. Dampers are shipped with drive rod inserted in drive blade. Drive rod may be extended up to 9" beyond end of the blade by loosening the U-bolt, drawing out the rod to desired length and then retightening the U-bolt. If required, 24"-and 36"-long zinc-plated steel drive rods are available.

CALL TAMCO CUSTOMER SERVICE WITH ANY QUESTIONS CONCERNING TAMCO DAMPERS 1-800-561-3449 DO NOT ADJUST LINKAGE MECHANISM. IF PROBLEM STILL EXISTS AFTER VERIFICATION AND CORRECT ACTION, CALL TAMCO CUSTOMER SERVICE. 69 V E R I F Y D A M P E R O P E R A T I O N 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. I N S T A L L A T I O N O F 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.

(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. (metric designation C100 x 9) (4.8 kN•m) G U I D E F O R 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.

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 Characteristic Curve for Opposed Blade Dampers 90 80 70 60 % 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. 100 50 40 30 20 10 0 0 Manufacturer A 75 90 Manufacturer B Manufacturer C Figure 2 Courbe caractéristique pour volets à lames opposées F L O W C 90 H A R A C T E R I S T I C S T A M C O 80 D A M P E R S 80 The pressure drop and flow of TAMCO Series 1000, 1500, & 9000 dampers were 70tested to AMCA Standard 500-89 at blade angles of 15, 30, 45, 60, 75 and 90 degrees. 70 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 control system manufacturers and the ASHRAE handbooks. % débit d'air 60 % Flow 60 100 90 50 40 30 40 Figures 1 and 2 show30 the tested “characteristic curves” for parallel and opposed blade TAMCO dampers, and com20 pare them to other published data. 20 10 10 0 0 0 15 30 45 60 75 0 90 Blade Angle 79 45 Blade Angle TAMCO 100 TAMCO 30 15 Manufacturer A Manufacturer B 15 30 45 60 75 90 Angle de rotation (lame) Manufacturer C TAMCO Manufacturier A Manufacturier B Manufacturier C S E R I E S 1 0 0 0 / 1 5 0 0 / 9 0 0 0 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. Installed flow characteristics at different damper authorities (1-100%) 100 90 1% 80 2% % Maximum Flow (Note that some manufacturers refer to characteristic ratios instead of damper authority.

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. 10 0 0 10 20 30 40 50 60 70 80 90 Damper Position Degrees Open Two approaches can be taken to size control dampers correctly. The first method, often used by system designers, is iterative. The designer selects 2 3 4 5 6 7 8 an arbitrary damper size, often the full dimension of the duct, determines Control Signal 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. 9 10V 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.

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. 81 S E R I E S 1 0 0 0 & 1 5 0 0 SOUND RATINGS NOTE: Tested dampers are “Flanged to Duct” type.

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.” Note that all technical information available on TAMCO’s web site at www.tamco.ca supersedes and takes precedence over all information contained within this catalog.
