Centrifugal Roof Exhauster, Downblast, Direct Drive


The DCRD Centrifugal Roof Exhauster is designed for roof mounted exhaust of relatively clean air in a wide variety of industrial and commercial applications. The DCRD 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 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.
