Industrial Control Fiberglass Damper - Airfoil Parallel Blade - FRP-91

Industrial Fiberglass Control Damper
Airfoil Blade

The FRP-91 fiberglass damper is used in applications where corrosive air exists for exhaust, air supply or pressure relief. It employs fiberglass airfoil blades, a rugged flanged frame, and options for ultra-low leakage in high pressure applications. The FRP-91 is ideal for high performance air intake and discharge applications.
