Model AC-93

Industrial Control Damper
Airfoil Blade

AC-93 industrial control damper employs heavy duty airfoil blades, a rugged flange frame, and options for ultra-low leakage in high temperature air and high pressure applications that make it ideal for high performance air intake and discharge applications where ultra-low leakage is critical.
