In many factories, transpiration acid mist, water vapor and heat will be produced during the production process. In order to reduce air pollution in the workshop, smoke ventilator will be installed in the factory. So how to analyze the working principle of the smoke exhaust ventilator? Automatic smoke ventilation window is widely used in light steel structure factories, commercial buildings, docks and other industries. The ventilation principle of smoke vent rooflight is to rely on the heat pressure or wind pressure formed by the temperature difference between indoor and outdoor to ventilate and exhaust smoke. The factory obtains fresh air to remove the smoke and exhaust gas to ensure the normal production.

Smoke hatch skylight is mainly used to control the opening and closing method to adjust the ventilation volume. Common control methods include ordinary control, intelligent control, and intelligent network control. In order to meet the needs of firefighting protection connection in industrial plants, roof vents can also achieve fire linkage control, such as wind, rain, smoke, and temperature. The smoke ventilator can realize firefighting linkage. In the event of an emergency such as a fire, the electric smoke exhaust window will quickly open to remove the smoke and reduce the loss. Under normal circumstances, the roof smoke vent will also maintain normal ventilation.
