UBH

Belt drive tubeaxial exhausters are ideally suited for roof exhaust applications that require the motor, drives and bearing located out of the airstream. The high velocity upblast discharge of the UBH disperses air high above the buildings roof. Capacities up to 61,236 CFM and up to 1 1/4 inch static pressure. UBH exhausters can operate continuously in air stream temperatures up to 200°F.   Features Housing Constructed of heavy gauge steel with charcoal baked enamel Rolled flange at each end for structural strength and rigidity Windband Constructed of heavy gauge steel with rolled flange  Cross channel member provides lateral rigidity and open position stop for butterfly dampers Butterfly Dampers Constructed of heavy gauge aluminum Stainless steel hinge pins and nylon bearings provide quiet, low friction operation Dampers open and close against rubber bumpers for quiet operation Water trough under damper hinge provides drainage for rain, melting snow and ice Magnetic latches hold dampers closed when exhauster not in use Aluminum Propeller Constructed of welded heavy gauge aluminum High efficiency circular arc airfoil blade design Precision balanced for smooth vibration free operation Heavy gauge steel propeller standard on UBH54 Bearings Permanently lubricated in an Acme D.S. split pillow block housing Bearings are resiliently mounted in neoprene rings Rated at L50 life of 200,000 hours 5 year limited warranty on Acme D.S. pillow block bearings Pillow block bearings standard on UBH60 Drive Assembly Cast iron drives sized for 150% of drive horsepower Static free, oil and heat resistant belts Motors Continuous duty motors by nationally recognized manufacturers Prelubricated ball bearings requiring minimum maintenance Belt & Bearing Enclosure  Streamline enclosure virtually eliminates turbulence and air drag Bearings are ventilated with outside air for longer life Motor Cover Heavy gauge steel cover protects motor and drive from adverse weather   Options/Accessories Roof Curbs Disconnect Switches Inlet/Outlet Guard Coatings Fusible Heat Release Damper Link SE Option U.L. Listed "Power Ventilator for Smoke Control Systems"
