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.
