Fire protection dampers are essential components usually positioned on the delivery and return air ducts of ventilation and air-conditioning systems. In the event of a fire, when the gas temperature within the duct reaches 70 °C, these dampers automatically close, effectively containing smoke and maintaining fire-resistant integrity for a specified duration. This crucial functionality acts as a formidable smoke barrier. Exhaust dampers, on the other hand, are integrated within the exhaust system ductwork or at the exhaust fan's suction entrance. Typically closed to meet air leakage standards, these dampers open manually or electronically during a fire or when smoke exhaust is necessary, ensuring efficient smoke removal. The fire damper is generally installed within the ventilation and air conditioning system ducts, whereas the smoke exhaust fire damper is predominantly placed within the smoke exhaust system ducts.
