Industrial Backdraft Damper - Fiberglass - Airfoil Blade - FRP-BD-94

Fiberglass Industrial Backdraft Damper
Airfoil Blade

The FRP-BD-94 fiberglass damper is used in applications where corrosive air exists for exhaust, supply or pressure relief. Backdraft dampers employ counter-balanced gravity operated airfoil blades and a rugged channel frame to restrict reverse airflow and to permit the forward flow of air in the intended direction. Adjustable counterbalances attached to the blade axles permit field adjustment to regulate start-to-open blade operation.
