Model BCS
Backward Curved - High Pressure
The BCS fan from Twin City Fan & Blower is a high
efficiency backward curved industrial fan designed for
handling relatively clean air in high pressure applications. Typical applications include combustion air,
product cooling, moisture blow-off, forced draft on
fluid bed boilers, and induced draft after baghouse
process blowers.
Because the BCS features a wider wheel and housing,
producing a high volume of air at a lower velocity, the
need for an expansion evasé is eliminated.
BCS fans are available with a variety of construction
options and accessories, offering the versatility and
flexibility required in today's industrial applications.

Housings
Arrangement 1
with unitary base
and belt guard
Heavy-gauge, reinforced, continuously welded housings
provide strength and durability for extended service
life — a necessity in all commercial and industrial
installations.
Outlet flanges for duct-connection as well as rigidity are standard. Inlet collars for slip-joint connection
and lifting lugs are also standard. All housings are
reinforced with rigid bracing to increase structural
integrity. The support angles are intermittently welded
and caulked between welds to prevent bleed-through
corrosion. Precisely positioned cutoff plates and aerodynamically spun inlet cones provide high efficiency
and smooth airflow through the fan.

ConstructionFeatures
BCS Wheel
The BCS wheel features heavy-gauge steel construction and a non-overloading wheel design, suitable for
applications requiring large volumes of air at moderate
to high pressures.
The high efficiency wheel features backward curved
blades of single thickness, continuously welded to the
rim and backplate.
A conical spun shroud (rim) makes BCS fans less
susceptible to the performance losses associated with
poor inlet conditions.
All BCS wheels are statically and dynamically balanced to grade G6.3 per ANSI S2.19 for smooth
operation prior to assembly of the fan, followed by a
final balance of the entire rotating assembly.
Shaft
Shafts are AISI-1018, 1040 or 1045 hot-rolled steel
accurately turned, ground, polished, and ring gauged
for accuracy. Shafts are generously sized for first critical speed of at least 1.43 times the maximum speed
for the class.
BCS Wheel
Bearings
Bearings are heavy-duty, grease-lubricated, anti-friction
ball or roller, self-aligning, pillow block type and are
selected for minimum average bearing life (AFBMA
L-50) in excess of 200,000 hours at the maximum
fan RPM.
Rotation and Discharge
Both clockwise and counterclockwise rotations are
available in various standard discharge positions. See
drawings on pages 28-41.
Temperature Limits
Standard construction designed for temperatures up
to 300°F. Optional construction available to handle up
to 800°F. See page 7.
Outlet Flange
Punched outlet flange is provided as standard construction on all sizes.
Arrangement 1
Mechanical Run Test & Final Vibration
Check
All fans are assembled for a mechanical run test as
well as final balance prior to shipment. Vibration readings are taken on both fan bearings in the axial, horizontal, and vertical directions at the specified speed.
Fans are balanced to 0.15 in/sec. peak or less.
Special Materials
BCS fans can be constructed of special materials such
as aluminum and stainless steel.

OptionalConstruction
Spark Resistant Construction
Fan applications may involve the handling of potentially
explosive or flammable particles, fumes or vapors.
Such applications require careful consideration by the
system designer to insure the safe handling of such
gases. Twin City Fan & Blower offers the following classifications of spark resistant construction per
AMCA Standard 99-0401-86. It is the specifier’s or the
user’s responsibility to specify the type of spark resistant construction with full recognition of the potential
hazards and the degree of protection required.
Type A:All parts of the fan in contact with the air or
gas being handled shall be made of nonferrous material — usually aluminum and limited
to 250°F.
Type B:The fan shall have a nonferrous
impeller and nonferrous ring about
ing through which the shaft passes
aluminum wheel and rub ring and
250°F.
Fan with
Split Housing
Split Housing
A flanged horizontal split housing is available on the
fan’s centerline. A pie-shaped split is also available
for wheel removal without disturbing the ductwork.
High Temperature Construction
Airstream temperatures above 300°F require high
temperature construction. See page 7 for construction
requirements. Insulation pins and complete fan insulation are available.
InletBoxes
To
Suit
Fan
D
C
Type C:The fan shall be so constructed that a shift of
the wheel or impeller or shaft will not permit
two ferrous parts of the fan to rub or strike.
This is accomplished with an aluminum inlet
cone and rub ring. This construction is limited
to 500°F. Construction to 800°F is available
using a steel inlet cone with copper/bronze
lining.
Notes:
1.Bearings shall be placed outside the airstream.
Therefore, do not use Arrangement 3 or 7.
2.The user shall electrically ground all fan parts.
Refer to AMCA Standard 99-0401-86 for full details.

Construction Requirements
The BCS product line is perfectly
suited for high temperature airstream
applications. The above chart refers
to fans of carbon steel construction. When aluminum (spark resistant)
or stainless steel construction is
required, additional fan modifications
may be required. Contact factory in
these cases.
Performance Correction For Temperature & Altitude
The performance tables in this catalog are based
on fans handling standard air at a density of 0.075
pounds per cubic foot. This is equivalent to air at
70°F at sea level (29.92 Hg barometric pressure). Thus,
when specified performance is at a density different
than standard, it must be converted to the equivalent
standard conditions before entering the performance
tables. The equivalent standard conditions can be calculated by using the Temperature and Altitude Density
Ratios shown below.

TypicalSpecifications
Fans shall be Model BCS, Backward Curved High Pressure Blowers, as manufactured by Twin City Fan & Blower,
Minneapolis, Minnesota.
PERFORMANCE — Fans shall be tested in accordance with ANSI/AMCA Standard 210 (air performance) and
300 (sound performance) in an AMCA accredited laboratory.
Fans shall have a sharply rising pressure characteristic extending through the operating range and continuing to
rise beyond the peak efficiency to ensure quiet and stable operation. Fans shall have a non-overloading design
with self-limiting horsepower characteristics and shall reach a peak in the normal selection area.
CONSTRUCTION — Fan housings and bearing pedestals shall be of heavy-gauge, continuously welded construction. Housings with partially welded construction are not acceptable. Housings shall be suitably braced to prevent
vibration or pulsation. Discharge flanges shall be provided for rigidity and duct connection. Discharge flanges are
punched as standard. All units are furnished with lifting lugs.
WHEEL — BCS backward curved wheels shall be single thickness, designed for maximum efficiency and quiet
operation, and shall be continuously welded to the rim and back plate. Partial welding is not acceptable on
backward curved blades. All wheels shall be statically and dynamically balanced.
SHAFT — Shafts shall be AISI 1018, 1040 or 1045 hot rolled steel, accurately turned, ground, polished, and ring
gauged for accuracy. Shafts shall be sized for the first critical speed of at least 1.43 times the maximum speed.
BEARINGS — Bearings shall be heavy duty, grease lubricated, anti-friction ball or roller, self-aligning, pillow block
type and selected for a minimum average bearing life (AFBMA L-50) in excess of 200,000 hours at the maximum
fan RPM.
DRIVE — Motor sheaves shall be cast iron, variable pitch on applications 20 HP and smaller, and fixed pitch
on 25 HP and larger. Drives and belts shall be located external to the fan casing and rated for 150% of the
required motor HP.
FINISH AND COATING — The entire fan assembly, excluding the shaft, shall be thoroughly degreased and
deburred before application of a rust-preventative primer. After the fan is completely assembled, a finish coat of
paint shall be applied to the entire assembly. The fan shaft shall be coated with a petroleum-based rust protectant. Aluminum components shall be unpainted.
ACCESSORIES — When specified, accessories such as access doors, drains, inlet and outlet flanges, belt guards,
shaft and bearing guards, outlet screens, outlet dampers, inlet vanes, spark resistant construction, split housings,
high temperature construction, shaft seals, inlet boxes, and shaft coolers shall be provided by Twin City Fan &
Blower to maintain one-source responsibility.
FACTORY RUN TEST — All fans prior to shipment shall be completely assembled and test run as a unit at the
specified operating speed or maximum RPM allowed for the particular construction type. Each wheel shall be
statically and dynamically balanced in accordance with ANSI/AMCA 204-96 “Balance Quality and Vibration Levels
for Fans” to Fan Application Category BV-3, Balance Quality Grade G6.3. Balance readings shall be taken by
electronic type equipment in the axial, vertical, and horizontal directions on each of the bearings. Records shall
be maintained and a written copy shall be available upon request.
GUARANTEE — The manufacturer shall guarantee the workmanship and materials for at least one (1) year from
startup or eighteen (18) months from shipment, whichever occurs first.
