An automatic damper HVAC is a device that is used to regulate the flow of air within a heating, ventilation, and air conditioning (HVAC) system. It is designed to open and close in response to changes in the temperature or pressure of the air, allowing for the efficient and safe operation of the system. Automatic dampers are typically installed in ducts, and they can be either motorized or non-motorized. Motorized dampers are usually powered by an electric motor, while non-motorized dampers are typically operated by a manual lever or a spring-loaded mechanism. Automatic dampers are essential components of an HVAC system, as they help to maintain the desired temperature and air flow in a space. They also help to reduce energy costs by preventing the system from running unnecessarily when it is not needed. Automatic dampers are also beneficial in preventing the spread of airborne contaminants, as they can be used to isolate certain areas of a building from the rest of the system.
