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.

Meets UL793 requirements
UBGMX exhausters with UF and SE options are designed and constructed to remove high temperature exhaust and smoke.
These specially equipped ventilators meet IRI (Industrial Risk Insurers) requirements for exhausting 500° F air for 4 hours and SBCCI’s “Standard Fire Prevention Code” requirements for exhausting 1000° F air for 15 minutes. The Butterfly
Damper on the SE option meets the requirements of UL 793 for automatically opening under snow or dust load in an emergency situation.

Variable speed range shown by arrows. 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.
Brake horsepower capability of an exhauster motor is dependent on the degree of cooling the motor receives from the air moving through the motor. 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.

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.
