Lennox 51H74 Damper Door Motor 110V 1RPM

The Lennox 51H74 Damper Door Motor is used in furniture specifically to control the airflow in the duct system. It uses a gear motor design that runs on a normal domestic supply voltage of 110 volts. When an electrical signal is passed to it, the motor turns a shaft at a low speed of revolution per minute (RPM). This rotation operates a damper door located in the duct system to open or close it. Due to this, it is effective in controlling the airflow systems and hence has a useful part in controlling the temperatures in different parts of the building to make it comfortable.
