UBG CONSTRUCTION FEATURES
REMOVABLE WINDBAND
Constructed of heavy gauge
galvanized steel. Removable
panels for easy access to fan
and dampers. (Size 72
windband shipped knocked
down; requires field assembly.)
Model UBG low silhouette belt drive exhausters are
ideally suited for moving large volumes of air.
Capacities range from 3,770 to 83,370 CFM and up
to ¾ inch static pressure. The UBG is a high
velocity exhauster design to discharge air up and
away from the building. Typical applications
includes all types of commercial and industrial
facilities such as warehouses, foundries, mills and
manufacturing plants.
BUTTERFLY DAMPERS
Constructed of aluminum for
ease of opening at low
velocities. Dampers provide
weather protection and
prevents backdrafts when fan
is not in operation.
LIFTING EYES
For ease in lifting onto the
roof deck.
BASE
Constructed of heavy
gauge galvanized
steel for weather
resistance.
HEAVY DUTY ALUMINUM
PROPELLER
Heavily reinforced, highly
efficient, cambered airfoil
blades, welded to hub and
precision balanced on
corrosion resistant coated fan
shaft.
MOTORS
Heavy-duty type with
prelubricated ball bearings
requiring minimum
maintenance.
DRIVE ASSEMBLY
Designed for 150% of driven
horsepower. Sheaves are
machined cast iron. Belts are
static free and heat and oil
resistant. Shafts have corrosion
resistant coating.
Variable speed drives are
standard for 5 HP and smaller.
Fixed speed drives are
standard for 7 ½ and 10 HP.
Pulleys have split taper bushing.
BEARINGS
Permanently lubricated bearings are
used in duplex split pillow block housing.
Bearings are resiliently mounted in
neoprene rings, providing extra
protection and vibration isolation. The
bearing assembly is rated at an L-50 life
of 200,000 hours and features Acme’s 5 year
limited warranty.

Variable speed range shown by arrows. Shaded lines represent fixed speed
for 7 ½ HP, 10 HP and 15 HP.
Performance shown is for Installation Type A: Free Inlet, Free Outlet.
Performance ratings include the effects of the damper in the airstream. Power
rating (BHP) does not include drive losses.
The sound ratings shown are loudness values in fan sones at 5 feet (1.524 m)
in a hemispherical free field calculated per AMCA Standard 301.
Values shown are for Installation Type A: Free Inlet fan sone levels.
The brake horsepower capability of an exhauster motor is dependent on the
degree of cooling the motor receives from the air moving through the motor.
The motor loading beyond the motor nameplate rating on Acme built
exhausters does not overheat the motor and is in accordance with the motor
manufacturer’s recommendations. It is therefore not detrimental to the motor
and is economically desirable.

OPTIONAL ACCESSORIES
Fusible Link Damper Lifters automatically open the
dampers when the air temperature exceeds 165°F.
Prefabricated Roof Curbs lined with fiberglass insulation
to reduce condensation and sound levels. Insures
compatibility between the fan and mounting curb.
Disconnect Switches for positive electrical shut-off and
safety when servicing fans. Switch is factory mounted on
bottom side of exhauster base housing through 1.50 HP
single phase and 2 HP three phase. Switch extends through
base and is operated from outside of exhauster for
maximum safety when servicing. For 3 HP and above,
NEMA 3R raintight switches mounted above curbcap.
Aluminum Construction is available for windbands and
curbcaps.
Energy Efficient Motors are available for most sizes.
Contact the factory for specific efficiency data.
Outlet Guards of heavy gauge steel mesh shield the fan
discharge from debris.
Steel Propellers are available with an acrylic epoxy finish.
Unitary Pillow Block Bearings are available with external
lube fitting when relubricatable bearings are required.
Magnetic Latches are available to minimize damper flutter
when fan is not in operation.
Coatings Aluminum and galvanized components remain
unpainted as a standard finish, but when required, are
processed through the finishing system to apply decorative
or special coatings. A high turbulence oven is used to
produce a baked on finish for most special coatings.
Decorative coatings are not baked on.
Decorative Coating Acme offers 16 popular colors for
decorative finishes utilizing an industrial grade enamel
applied to the exterior of the fan.
Note: For any coating selected, the user assumes
responsibility for the ultimate effect on the coating and
equipment due to the corrosive agent, its concentration,
temperature and moisture content.
Belt Cover is available with UBGMX to isolate the belt and
drive components from airstream contaminants (standard
with UF and SE options). Performance can be estimated
by applying a 7.5% reduction on the system curve when
using the belt cover.
Special Coatings Products receiving special coatings
have components painted before assembly. Fasteners are
not painted.
Acrylic Epoxy This product provides a more durable
•
surface.
Carboline Sanitile (Eisenheiss) This air dry synthetic
•
polyester forms a black coating that offers greater
resistance to most organic and inorganic acids.
Heresite (Air Dry) A phenolic coating with greater
•
resistance to most organic and inorganic acids.
Insulmastic A black asphalt based mastic that provides
•
some condensation control, sound deadening and
corrosion resistance.
