Application
The REF-II roof centrifugal fans are designed for roof mounted exhaust of relatively clean air in a wide variety of industrial and commercial applications.
REF-II features a high efficiency, non-overloading backward inclined centrifugal wheel precisely matched to a deep spun venturi.
The wheel, 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.
