CWD Centrifugal Wall Exhaust 9 inch 1221 CFM CWD09MH1AS

Centrifugal Sidewall Exhauster, direct drive.

These sidewall exhausters are used to exhaust relatively clean air from a variety of industrial, commercial and institutional buildings such as machinery and equipment rooms, storage areas, office buildings, restaurants, retail stores, schools and similar buildings.

The non-overloading centrifugal wheel with its high static pressure capability, makes it suitable for either ducted or non-ducted applications.

The spun aluminum exterior provides a pleasing appearance, weather proof construction and resistance to corrosion. The low silhouette design is less noticeable on the building exterior and the removable dome provides easy access to the fan interior for service and cleaning.

Direct drive units use smaller diameter wheels, resulting in low sound levels and quiet operation. They have no belts or fan bearings to maintain or adjust and consequently require very little maintenance.
