Relief dampers are a type of valve used to regulate the flow of air or other gases in a system. They are typically used in ventilation systems to ensure that the pressure in the system remains within a certain range. Relief dampers are designed to open when the pressure in the system exceeds a certain level, allowing the excess pressure to be released. This helps to maintain a safe and comfortable environment, as well as preventing damage to the system. Relief dampers can also be used to regulate the flow of air in an air conditioning system, allowing for the proper distribution of air throughout the building. In addition, relief dampers can be used to control the amount of air entering a building, preventing the system from becoming over-pressurized. Relief dampers are an essential component of any ventilation system, and they can help to ensure that the system operates safely and efficiently.
