HVAC motorized dampers are an essential component of many commercial and residential heating, ventilation, and air conditioning (HVAC) systems. These devices work by using electric or pneumatically powered motors to open and close off-chambers and vents in the system that adjust the airflow and temperature in a building. By reversing these dampers at different times of day, HVAC technicians are able to more precisely control the climate in a given space while optimizing air quality, energy efficiency, and comfort. Put simply, the official business definition of HVAC Motorized Dampers is electromechanical units designed to effectively regulate air flow throughout a building’s HVAC system.
