Mega Flow Butterfly Fans

Protection from the weather

Front Shutter Door

Front shutter doors offer protection from harsh weather conditions, such as wind and moisture, while the fan is not in use.

Arched Side Cone Panels

Cumberland fans are designed so they can be mounted close together when fan spacing is an issue.

Smooth Operation and Long Life

Drive Trains

Easy access drive trains are standard on all belt drive fans. Large, cast iron, high-quality greasable pillow block bearings are used for longer life. Large pulleys allow for longer belt life and smooth operation. An automatic belt tensioner ensures proper belt tension.

Efficiency and Airflow

The strong butterfly ring weldment with a V-channel vertical brace helps block light and add strength. Air diverters improve airflow and the neoprene baffle hinge is designed for smooth, consistent operation.
