Positive pressure air supply vent manufacturer, latest quotation of positive pressure air supply vent, Detong Air Conditioning Equipment Factory Telephone number 3 Function: When a fire occurs, the electric actuator inside will open the air vent, and the temperature sensor smoke sensor or manual fire alarm will turn on, and the top of the tower The positive pressure fan automatically turns on to pressurize the air supply shaft. The front room of the stairs will continuously supply air to the front room through the positive pressure air supply port, so that the front room maintains positive pressure and ensures that the smoke will not be in this The area spreads, giving people room to escape. When the temperature is higher than ℃, there is no possibility for people to escape. The internal fuse will blow and the air vent will automatically close to prevent the spread of fire. Application: The national fire protection and smoke exhaust design specifications for high-rise buildings stipulate that the following locations should be equipped with independent mechanical smoke exhaust systems, smoke-proof stairs that do not have natural smoke exhaust conditions, and fire elevator front rooms or shared front rooms. , Use smoke-proof stairs with natural smoke exhaust, which do not have a front room with natural smoke exhaust.
