Belt-drive panel exhaust fans are typically quieter and provide more control over the fans' blade speed and airflow than direct-drive panel exhaust fans. Belts connect the fans' motors to their fan blades. Belt-drive panel exhaust fans can be mounted vertically or horizontally on the ceiling for use in air supply and air intake applications. They are better suited than direct-drive fans for high airflow (≥ 2000 cfm) or high static pressure (≥ 0.50") applications. These fans come with a drive package that includes a motor, pulleys, belts, and bushings, which saves time compared to purchasing all of these components separately.

These fans do not come with a drive package, so they can be used with a compatible motor, pulleys, belts, and bushings that users already have on hand.
