Fans for smoke extraction

It is suitable for ventilation and fire control of high-rise buildings, subway tunnels, underground stores etc. This fan has a dual-speed engine, but works well at a low speed. In the event of a fire, the fan automatically switches to high speed and removes smoke,ensuring safe evacuation from the spot of fire. The transmitted air should not contain adhesive material, dust or grain. If a fan is used for fire control, it can operate continuously for more than 30 minutes, provided that the temperature of the smoke is up to 280 °C.
