Johnson Controls DMPR-KC054 Blade Arm Kit

The Johnson Controls DMPR-KC054 Blade Arm Kit is a spare part for HVAC systems. It is a small steel part that links a damper blade, the metal plate that regulates the flow of air, to the motor in an AHU. AHUs are a component of HVAC systems that control temperature and air quality within a structure. The kit consists of a blade arm and associated hardware for installation. The arm is screwed directly to the damper blade. One end of the blade arm is fastened to the linkage rod or shaft of the damper actuator, the mechanism that operates to open or close the damper blade.
