UPBLAST PROPELLER ROOF EXHAUSTERS

MODEL OVERVIEW
Models UBB and UBX are high capacity roof mounted exhausters rated from 5,900 to 78,000 CFM.
They are general ventilation units designed to economically remove large volumes of air, fumes and
vapors from commercial and industrial buildings such as warehouses, manufacturing and assembly
plants, distribution centers, chemical plants, foundries and paper mills.
Straight-through air ow design results in maximum exhaust efciency. During operation, high air ow
velocity opens buttery dampers and prevents rain or snow from entering. Dampers close and cover
the venturi opening when unit is not in use.
The roof mounted location eliminates interference with processes and equipment inside the building. It
also permits locating the exhauster over a source of heated or contaminated air, allowing direct upward
venting to the outside, unlike wall mounted exhausters which may move contaminated air through
adjacent work spaces.
Belt drive units usually operate more quietly and afford easier performance adjustments, while direct
drive models require less maintenance.
