The heavy-duty, double-flanged, channel-frame-style dampers with double-thickness fabricated airfoil blades are qualified for pressures as high as 15 psi, covering many applications in Unified Facilities Criteria and General Services Administration codes and standards, including Charge Weight I at 82 ft.
