About Belt Drive Exhaust Fans

Get quieter operation and more control over fan blade speeds by choosing belt driven fans instead of direct drive fans. The fan blade speed can be adjusted to move large volumes of air as needed. Belt drive fans produce more friction among moving parts than direct drive fans, so they may be less efficient and require more maintenance.

These fans have a low-profile frame that requires minimal mounting space and can be mounted vertically or horizontally. They require a compatible drive package with a motor, belt, bushings, and sheaves for operation.
