Features:

·   Each TR low pressure unit is a two position, spring open, power closed supply air damper. The dampers are available from 6” – 16” round, with a maximum pressure differential of .5” W.C.

·   The 6” – 10” damper cylinders are fabricated from 24 gauge steel: the 12” – 16” cylinders from 22 gauge steel.

·   Each cylinder features three rolled beads, which provide maximum structural integrity. The trailing end is crimped for ease of installation. Positive air seal is accomplished without the use of gaskets, linkages or set screw adjustment.

·   All TR dampers feature 24V ac, full stall motors, which do not require use of end switches to terminate travel.

·   Each TR is equipped with a motor terminal board, which also provides a damper closed LED indicator.

·   TR dampers can be paralleled to provide additional CFM capacity when required.

·   Damper motors are easily removed for damper shaft and gear inspection. Each actuator hat section is insulated to prevent condensation.
