Features:

·   Each TREC-BM low pressure unit is a two position, spring open, power closed single blade supply air damper, The dampers are available from 10” x 8” to 24” x 12”, in 2” increments.

·   Damper blade shafts are fully enclosed in Celcon bushings to reduce friction and ensure quiet operation, The motor and shaft are internally enclosed within the damper assembly.

·   A high density foam rubber gasket with a welded galvanized angle affords an efficient seal to minimize blade to frame leakage, All TREC-BM dampers feature 24V ac, full stall motors, which do not require use of end switches to terminate travel, The damper consists of a galvanized steel frame and heavy duty bottom plate, The TREC-BM dampers are rated for a maximum pressure differential of 0.5” W.C, Each TREC-BM is equipped with a field wiring terminal board, accessed from the bottom plate with a red LED to indicate when the damper is being powered closed.

·   TREC-BM dampers can be paralleled to provide additional zone CFM capacity when required.

·   The TREC-BM offers a simple slide in installation, and motors are easily removed for shaft and pin inspection, Actuator is Synchron, 24 vac Input, 24 vac Supply Voltage
