Automatic dampers are an important component of a HVAC system, as they are responsible for controlling the air flow throughout the system. They are used to regulate the temperature and air flow in different areas of a building, and can be used to control the amount of air that is being used in a particular area. Automatic dampers are typically made of metal, and they are connected to a motor that can be programmed to open and close the damper in order to regulate the air flow. The damper can be adjusted manually or automatically depending on the needs of the system. Automatic dampers are essential for ensuring that the air flow is balanced throughout the building, and they can help to reduce energy costs by reducing the amount of air that is being used. Automatic dampers are also important for maintaining the comfort level of the occupants in the building, as they can help to keep the temperature and air flow at an optimal level.
