Centrifugal Roof Exhauster, Upblast, Belt Driven


The BCRU Centrifugal Roof Exhauster is designed for roof mounted exhaust of relatively clean air for applications that require exhausted air to be moved up and away from the building, and where re-entry into the building supply air is possible. The BCRU features a high efficiency, non-overloading backward inclined centrifugal impeller precisely matched to a deep spun venturi. The impeller, motor and drive assembly are completely isolated from the fan supports by rubber isolators to reduce the transmission of noise and vibration. The top cap also provides complete protection for the motor and drive assembly while allowing quick access to these components without the need for tools.
