Model Overview

UBSRD units are high capacity, belt driven roof mounted exhausters rated from 4,900 to 52,000 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 up 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 UBSRD is available without the belt and bearing enclosures.

Straight-through airflow design results in maximum exhaust efficiency. During operation, high airflow velocity opens butterfly dampers and prevents rain or snow from entering. Dampers close and cover the venturi opening when the 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 workspaces.
