AMCA 260 Tested
Twin City Fan & Blower offers specially modified
versions of the BAF-SW and BC-SW fans
designated as BAIFE and BCIFE, respectively
for induced flow laboratory fume hood exhaust
applications.
The BAIFE and BCIFE fans consist of a single-wide
centrifugal unit, a choice of one of four different
nozzles and a specially designed windband to
maximize dilution ratio (overall outlet volume/lab outlet
volume) and plume height.
Available in five (5) arrangements, both belt and
direct drive, the BAIFE and BCIFE are capable of
generating an induced flow to meet stringent roof
exhaust requirements.
Application
BAIFE/BCIFE
The BAIFE and BCIFE Induced Flow Exhaust Fans are
intended for use in exhausting laboratory fumes and
hazardous chemicals in such a manner that diminishes the likelihood of concentrated, contaminantladen air from being re-entrained into the building's
intake or makeup air. This unit is commonly used in
exhaust systems for universities, schools, hospitals,
research facilities, laboratories, restaurants and waste
water treatment plants.
Induced flow exhaust fans dilute contaminated air at
the outlet as well as increase the outlet volume of
the fan. This accelerates the discharge air, increasing
plume height without a tall stack.
Sizes
12.25" to 66.0" wheel diameters
Performance
Airflow to 129,000 CFM
Static pressure to 15" w.g.

Wheel Designs
BAIFE airfoil wheels are available in sizes 122 through
165 in aluminum construction only using extruded
aluminum blades. Sizes 165 and larger are constructed of steel using die-formed hollow airfoil blades,
both sides of the blades continuously welded to the
conical spun inlet shroud (rim) and the backplate.
BCIFE wheels are constructed of steel using flat
single thickness blades, solid welded to the rim and
backplate. Flat blades lend themselves well to high
temperature environments or where high humidity or
light dust loading may be present.

Centrifugal Wheel
The use of a conical spun shroud (rim) makes BAIFE/
BCIFE fans less susceptible to the performance losses associated with poor inlet conditions. Both wheels
are designed for a stable air performance throughout
the operating range. The impellers are statically and
dynamically balanced to grade BV-3 per AMCA 204
for smooth operation prior to being assembled in the
fan, followed by final balance of the entire rotating
assembly by Twin City Fan & Blower.

FumeExhaustDefinitions
Bypass Air
Ambient air that is drawn through the bypass air
plenum and mixed with the lab exhaust to increase
dilution and plume rise. Bypass air is primarily used
in variable volume applications to maintain a constant
discharge volume but can also be used to increase
overall exhaust volume and dilution. (See diagram to
left.)
QT
Dilution Ratio
The ratio of the total fan outlet volume to the lab
exhaust volume. (Total Volume/Lab Exhaust Volume).
Value includes any additional bypass air in the calculation. (See diagram to left.)
QE
QE
Entrainment Air
Air that is entrained (induced flow) through the windband and fan housing, mixed with the laboratory
exhaust to increase the dilution ratio and plume rise.
(See diagram to left.)
Entrainment Ratio
QF
The ratio of the total fan outlet volume to the fan
inlet volume. (Total Volume/Fan Inlet Volume - see
diagram to left.)
Nozzle
QB
Device located internal to the fan housing, providing
fume exhaust air to accelerate upon entrance to the
windband. Several nozzles per fan size are available
on the BAIFE and BCIFE; low-velocity, medium-velocity, high-velocity and extra-high-velocity. Each nozzle
provides different flow characteristics. Nozzle should
be selected based on the application requirements.

AMCA260Testing
The following illustrations describe the procedure for
determining the total laboratory exhaust fan discharge
flow. The total discharge flow is the sum of inlet
airflow and entrained airflow. The key requirement to
AMCA 260 is the variable resistance box. This box
allows the measurement of total discharge flow (Ps
= 0 in. w.g. to simulate discharging the fan to atmosphere) at all points along its fan curve.
Without the variable resistance box, the
entrained airflow can only be measured
at the free air point of its fan curve. The
entrained airflow obtained can be used to
calculate an effective plume height. Therefore,
AMCA 260 certification is necessary to ensure
the laboratory exhaust fan specified is providing the
plume rise and entrainment submitted.

ConstructionFeatures
Nozzle
Located between the fan housing and the windband,
the nozzle efficiently increases the speed of the
exhaust stream into the windband. The accelerated
air entrains surrounding ambient air into the windband
diluting the building exhaust.
Windband
Windbands designed to maximize plume height and
entrainment air. Constructed of heavy-gauge steel
for strength and rigidity, the windband is mounted
directly to the fan housing.
Housing
Bolted Access Door
All fan housings are continuously welded to provide
strength and durability for extended service life — a
necessity in all commercial and industrial installations. The structural frame of the housing is designed
to support the windband and nozzle at cross wind
speeds up to 125mph without the use of guy-wires
for rigid mounted fans.
Lifting lugs are standard on all fans. Precisely positioned cutoff plates and aerodynamically spun inlet
cones provide high efficiency and smooth airflow
through the fan.
Bolted Access Door
Windband and Nozzle
Drain
Wheel area access door for inspection or cleaning
of the wheel.
Drain
A drain coupling welded to the lowest point of the
housing allows drainage of condensate from fan
housing.
Bearings
Bearings are heavy duty, grease lubricated, spherical
roller or adapter mounted anti-friction ball, self-aligning, pillow block type, selected for minimum average
bearing life (AFBMA L-10) in excess of 200,000 hours
at the maximum fan RPM.
Shaft Seal
Shaft
Shafts are AISI Grade 1040 or 1045 hot-rolled steel
accurately turned, ground, polished, and ring gauged
for accuracy. Shafts are generously sized for a first
critical speed of at least 1.43 times the maximum
speed for the class.
Shaft Seal
The standard shaft seal reduces leakage and protects
the bearings from a contaminated airstream. It is
constructed of non-asbestos woven fibrous materials (ceramic felt) compressed between an aluminum
cover plate and the fan housing. A ceramic felt shaft
seal does not make the fan gas tight. A variety of
special seals is available for low leakage applications
requiring more positive protection, including mechanical type stuffing boxes

Mixing Plenum Box
The mixing plenum box features modular construction
allowing for multiple configurations and effortless retrofitting. Bottom intake is standard, side intake option
available upon request.
ProductAccessories
Isolation Damper
Standard isolation dampers, constructed of heavy
duty galvanized steel as standard, are typically used
on multi-fan mixing plenum boxes to isolate individual
fans. Available in extruded aluminum construction
upon request.
Bypass Damper
Used to maintain outlet velocities by allowing a constant volume at the fan discharge when exhaust air
is reduced. Constructed of heavy duty galvanized
steel as standard, extended aluminum available upon
request.
Roof Curb
Isolation Damper
Bypass Damper
Disconnect Switch
Roof Curb
Standard roof curbs are constructed of heavy duty
galvanized steel and include 1-1/2” thick insulation.
Vortex Breaker
Installed in the mixing plenum box at the fan inlet,
the vortex breaker minimizes air ‘swirl’. Recommended
for multi-fan configurations and intakes that are not
directly across from the inlet of the fan.
Disconnect Switches
A NEMA 1, 3R, 4 or 7/9 safety disconnect switch is
available for positive electrical shutoff of the fan and
the protection of service personnel. Disconnects are
available shipped loose for field mounting and wiring
or factory mounted and wired, excluding NEMA 7/9
disconnects.
V-Belt Drive
V-belt drives offer an economical yet flexible means
of transmitting power to the fans.
Belt Guards
A belt guard protects personnel from the moving
drive parts. Both standard and totally enclosed type
guards are available.
Shaft and Bearing Guards
Solid sheet metal guards cover shaft and bearings
and come with extended lube lines to a common
point out either side of the guard. A guard spanning
the shaft between the bearings is also available to
provide easy access to bearings for lubrication and
vibration monitoring.
Spark Resistant Construction
Various grades of spark resistance are available as
defined by AMCA.
Piezometer Ring (Airflow Measuring System)
A piezometer ring is available as part of an airflow
measuring system, based on the principle of a flow
nozzle. The flow can be calculated by measuring the
pressure drop through the inlet cone. No tubes or
sensors are inserted in the high velocity airstream
which could obstruct airflow. A differential pressure
transducer and digital display can also be provided.
Piezometer Ring Mounted at Throat of Inlet Cone
Based on Twin City Fan laboratory tests, the system
was determined to be accurate within +/-5%. For
more information, refer to Twin City Fan Engineering
Supplement ES-105.
High Temperature Modifications
(BCIFE Only)
Standard fan design temperature is 300 °F (150 °F for
Arrangement 4). High temperature modifications allow
the BCIFE to handle airstream temperatures to 500°F.
Modifications include one or more of the following
items depending on operating temperature: shaft seal,
high temperature grease, one (1) expansion bearing
shaft cooler, heat shield (Arr. 9 and 10), high temperature aluminum paint. Consult Twin City Fan for more
information and restrictions with high temperature fan
applications and material derating factors.

accredited laboratory. Fans shall be licensed to bear the
air. Sound certification shall apply to both inlet and outlet
Fans shall be designed for maximum efficiency. Fans shall have a sharply rising pressure characteristic extending
through the operating range and continuing to rise well beyond the efficiency peak to assure quiet and stable
operation under all conditions. Horsepower characteristics shall be truly self-limiting and shall reach a peak in the
normal selection area.
HOUSING — Housings are to be of heavy gauge, continuously welded construction. Housings with lock seams
or partially welded construction are not acceptable. Housings shall be suitably braced to prevent vibration or
pulsation. Fan housings shall have tapered spun, aerodynamically designed inlet cones or shrouds providing
stable flow and high rigidity. Model BAIFE shall include outlet nozzle, windband, access door and drain with plug.
Wheel — Fan wheels shall be die-formed airfoil blade type, continuously welded to the rim and back plate,
designed for maximum efficiency and quiet operation. Partial welding will not be acceptable on airfoil blades.
Smaller sizes may use extruded aluminum blades. All BAIFE wheels shall be statically and dynamically balanced.
The complete fan assembly shall be test balanced at the operating speed prior to shipment.
Shaft — Shafts shall be AISI 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 life (AFBMA L-10) of 200,000 hours at the maximum fan RPM.
Drive — Motor sheaves shall be cast iron, variable pitch on applications 10 HP and smaller, and fixed pitch
on 15 HP and larger. Drives shall be selected to provide a minimum 2.0 service factor.
NOZZLE AND WINDBAND — A nozzle and windband combination shall be provided to efficiently induce ambient airflow from outside the fan housing and increase discharge velocities to be a recommended minimum of
3,000 FPM without significantly affecting BHP requirements. The windband shall provide a minimum discharge
height of between 84" and 120" from roof surface.
OPTIONAL ACCESSORIES — Where required the fans shall be provided with:
• AMCA "A", "B" or "C" spark resistant construction
• Modular mixing plenum box
• Bypass damper with actuator
• Isolation damper with actuator
• Disconnect switches
