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 impeller 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.

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 Impeller
The BCS impeller features heavy-gauge steel construction and a non-overloading impeller design, suitable for applications requiring large volumes of air at
moderate to high pressures.
The high efficiency impeller 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 impellers are statically and dynamically
balanced to grade G6.3 per ANSI S2.19 (3.8 mm/s
rms) 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 Impeller
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 L10 in
excess of 40,000 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 150°C. Optional construction available to handle
up to 425°C. See page 7.
Arrangement 1
Outlet Flange
Punched outlet flange is provided as standard construction on all sizes.
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 3.8 mm/s rms. peak
or less.
Special Materials
BCS fans can be constructed of special materials
such as aluminum or stainless steel.

OptionalConstruction
Spark Resistant Construction
Fan applications may involve the handling of potentially explosive or flammable particles, fumes or
vapour. 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 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 120°C.
Type B:The fan shall have a nonferrous impeller
or impeller and nonferrous ring about the
opening through which the shaft passes —
usually aluminum impeller and anti-spark
track and limited to 120°C.
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 impeller removal without disturbing the ductwork.
High Temperature Construction
Airstream temperatures above 150°C require high
temperature construction. See page 7 for construction requirements. Insulation pins and complete fan
insulation are available.

Type C:The fan shall be so constructed that a
shift of the impeller 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 anti-spark
track. This construction is limited to 260°C
Construction to 425°C is available using a
steel inlet cone with copper/bronze lining.
Notes:
1.Bearings shall be placed outside the airstream.

Construction Requirements
The BCS product line is perfectly
suited for high temperature airstream applications. The chart on
the left 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 curves in this catalogue are based
on fans handling standard air at a density of 1.2
kg/m3. This is equivalent to air at 21°C at sea
level (101.325 kPa 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
curves. 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.
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.
IMPELLER — BCS backward curved impellers 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 impellers 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 impeller
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.
