MODEL UBRD
REMOTE DRIVE UPBLAST PROPELLER ROOF EXHAUSTER
2 year fan housing warranty, 1 year motor warranty
MODEL OVERVIEW
Model UBRD units are high capacity belt driven roof mounted exhausters rated from 4,500 to 72,000
CFM. The motor and drives are located outside of the exhaust airstream, making these units especially
suited for the removal of heated or contaminated air from commercial and industrial buildings or
processes where these conditions exist. All models are capable of continuous operation exhausting air
to 200˚F.
The remote drive construction allows for easy rooftop belt and motor access for maintenance. For
increased air performance (in clean conditions) with the same easy maintenance access, the UBRD is
available without the belt and bearing enclosures.
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.
