An automatic balancing damper is a device used to regulate the flow of air or other gases in a ventilation system. It is designed to automatically adjust the flow of air to maintain a desired level of air pressure in the system. This helps to ensure that the system is operating efficiently and safely. The damper is typically made of metal and is connected to a motor that is controlled by a computer. The motor is programmed to open and close the damper depending on the air pressure in the system. This allows the system to maintain a consistent air pressure, regardless of changes in the environment or other factors. Automatic balancing dampers are commonly used in commercial and industrial buildings, as well as in residential homes. They are an important part of any ventilation system, as they help to ensure that the system is operating at peak efficiency.
