Centrifugal Wall Ventilator,
Belt Driven


The AWX centrifugal wall ventilator is designed for horizontal wall-mounted configurations exhausting clean air in a wide variety of industrial and commercial applications. The AWX 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.
