Exhaust Fan 42 in Blade, 20,652 30,825 cfm

In Packaging?: Yes

Damaged?: Unknown


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 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.
