Each TR FAD is a two position, power open, spring return single blade fresh air damper. The dampers are available from 6” to 16”. The TR FAD dampers are rated for a maximum pressure differential of .5” W.C.
The damper consists of galvanized steel and heavy-duty front plate. Damper blade shafts are fully enclosed in Celcon bushings to reduce friction and ensure quiet operation. A high-density foam rubber gasket with a welded galvanized angle affords an efficient seal to minimize blade to frame leakage.
All TR FAD dampers feature 24V ac, full motors, which do not require use of end switches to terminate travel. Each TR FAD is equipped with a motor terminal board, for positive field wiring.
The TR FAD offers a simple slide in installation, and motors are easily removed for shaft and pin inspection.
