Commercial control dampers are used in buildings to regulate the flow of air in an HVAC system. More specifically, it’s a valve or plate that stops or regulates the flow of air inside a duct, chimney, Variable Air Volume (VAV) box, air handler, or other air handling equipment. Zone dampers as used in home HVAC systems are usually electrically powered. The damper sometimes can also be used for the other purposes like for directing an air stream to flow in a particular direction, just by allowing the blades to turn at the precise angle. Another style of electrically powered damper uses a spring-return mechanism and a shaded-pole synchronous motor. HVAC systems are typically divided up into multiple zones. These dampers can be fixed within the duct itself and can be automatic or manual. Some dampers are adjustable metal plates installed inside of a duct to close off or control the volume of heating and air conditioning in a specified room or area. Automatic dampers are used to regulate airflow constantly and are operated by electric or pneumatic motors, in turn controlled by a thermostat or building automation system.
