ConstructionFeatures
Housing
Housing is constructed of heavy gauge steel and is
continuously welded on top and bottom to prevent
grease leakage. Lifting lugs are welded to the housing
as standard.
Drive Assembly
Adjustable pitch V-belt drives with cast iron sheaves
and heat resistant belts are selected at 150% of the
driven motor horsepower.
Discharge Scoop
The discharge scoop is sealed to the fan housing with
a high temperature gasket to prevent grease leakage
onto the roof. It can be easily removed for cleaning
and maintenance. A 2” NPT drain is welded to the
bottom of the scoop to allow for grease to be collected in a grease trough or piped and collected at
remote location (local codes may vary).
Drive Assembly
Motor Cover
Encloses the motor, drives and bearings from the
elements. Vents allow ambient air in to cool motor,
drives and bearings. The top panel of the motor cover
is removed with simple hand tools for maintenance
and inspection of motor and drive components.
Curb Cap
The curb cap is constructed of heavy gauge steel and
is continuously welded. Mounting holes in the curb
cap are prepunched to ensure correct attachment to
the roof curb. A curb hinge is provided as standard.
Curb caps are complete with stops at the corners to
prevent over rotation and handles to assist with lifting.
Motor Cover
Discharge Scoop
Disconnect Switch
Standard on all units. Fans are provided with a NEMA-3R
type disconnect switch mounted to the outside of the
fan housing. Switches are prewired from the motor.
Drive Frame
Vibration isolators support and isolate the motor, shaft,
bearings and wheel assembly from the unit, reducing
noise transmission into the ductwork.
Curb Cap & NEMA-3R Disconnect Switch
Wheel
Backward inclined wheel is non-overloading and constructed of heavy gauge steel. Wheel is fully welded
and includes fins on the backplate to draw cool air
across the motor, drives and bearings.
Bearings
Heavy duty grease lubricated pillow block bearings
complete with zerk fittings for simple and easy lubrication. Bearings have been selected to have an L-10
life in excess of 100,000 hours.

ProductAccessories
Swingout Wheel Design
Available as an optional construction, the swingout
wheel design allows for the wheel to pivot out of the
fan housing for simple cleaning and maintenance. A
rod prop is standard with the swingout wheel option
to keep the assembly open as well as a lockable
hasp. See page 5 for more details on the swingout
wheel option.
Scroll Access Door
A bolted access door on the fan scroll is available to
provide access to the wheel for cleaning and inspection.
A high temperature gasket seals the access door to
the scroll.
Grease Box
The heavy gauge galvanized grease box is designed
to trap the grease in and allow the water to run off
onto the roof.
Grease Box
Auto Belt Tensioner
The auto belt tensioner keeps constant tension on
the belt which reduces slippage and extends belt life.
Available with single-groove drives only.
NEMA-4 Weatherproof Disconnect Switches
A NEMA-4, water and dust tight disconnect is available mounted and prewired from the motor.
Vented Curb Extension
NEMA-4 Disconnect Switch
Prefabricated Roof Curbs
Extensions work to extend the height of the roof
curb and fan discharge. Extensions are sized to meet
NFPA discharge height requirements of 40” above the
roof with an 12” tall roof curb. Standard curb extension is galvanized steel.
Extended Discharge
For applications where it is required to increase the
discharge height of the unit due to local codes or
close proximity to the inlets of supply units, an extended discharge is available. On fan sizes 150 and
above, an access door on the top of the fan housing
is standard to provide access to the inside of the
housing for cleaning.
Prefabricated Roof Curbs
Extended Discharge
Prefabricated roof curbs are available in heavy duty
galvanized steel or aluminum construction, in heights
of 8", 12", or 18". The standard curb (vented self
flashing) is provided with a 3/16" polystyrene gasket.
The standard self flashing curb design features continuously welded seams for added rigidity and moisture
protection. Prefabricated curbs are also available in
raised cant, pitched and peak models. Refer to Catalog 4910 for complete details on roof curb options.
Special Coatings
Available coatings include air-dried enamel, air-dried
epoxy, and Heresite (air-dried phenolic). Contact your
Twin City Fan & Blower representative for more information on available coatings and colors.

PERFORMANCE — Performance ratings shall conform to AMCA Standard 205 (fan efficiency grade), 211 (air
performance) and 311 (sound 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 be licensed to
bear the AMCA certified ratings seal for both sound and air, and fan efficiency grade (FEG).
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. All fans shall
be capable of operating over the minimum pressure class limits as specified in AMCA Standard 99.
Model BHRE shall be UL 762 listed for the exhaust of grease-laden air. Fans shall bear a permanently attached
nameplate displaying model and serial number of the unit for future identification.
CONSTRUCTION — Fan housings shall be 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. Housings shall have tapered spun, aerodynamically designed inlet cones or shrouds providing
stable flow and high rigidity. The curb cap shall include prepunched mounting holes for ease of installation.
Lifting lugs shall be welded to the fan housing for ease of handling and installation. Vibration isolators support and isolate the motor, shaft, bearings and wheel assembly from the unit, reducing noise transmission into
the ductwork.
TypicalSpecifications
Fans shall be Model BHRE Belt Driven Hinged Restaurant Exhaust Fans, as manufactured by Twin City Fan
& Blower, Minneapolis, Minnesota.
WHEELS — Backward inclined wheels shall be single thickness plate type designed for maximum efficiency and
quiet operation and shall be of the non-overloading type. BHRE wheels shall be constructed of heavy gauge
steel with welded (not riveted) blades. All wheels shall be statically and dynamically balanced.
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, self-aligning, pillow block type
and selected for a minimum L-50 life in excess of 200,000 hours at the maximum fan RPM.
DRIVE — Motor sheaves shall be cast iron, and supplied as either variable pitch or fixed pitch. BHRE drives
and belts shall be rated for a minimum of 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.
ACCESSORIES — When specified, accessories such as swingout wheel, extended discharge, grease box, roof
curb, etc., 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 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 its BHRE fans for at
least one (1) year from startup or eighteen (18) months from shipment, whichever occurs first.
