Smoke dampers and smoke damper difference between smoke dampers are mainly used in ventilation and air conditioning systems, fire dampers, smoke dampers usually installed in the fire separation of the computer room ventilation and air conditioning systems is 70 degrees Celsius damper, usually normally open, when the duct temperature reached 70 degrees in the flue gas is automatically shut down. Control mode automatically. Smoke damper is mainly used in mechanical exhaust system is 280 degrees Celsius damper, damper purchase, usually is normally closed when the fire broke by automatic fire alarm interlock signal automatically open fire damper specifications, along with a manual actuator, It can be opened manually or remotely opened fire control center (ie joint control, manual control, automatic control of three ways), usually installed in the exhaust port, the duct through the fire and smoke partitions separate room at the exhaust duct and through the wall at the flue gas duct when the temperature reaches 280 degrees closed.
