Together with a good European relationship, we provided 138x F400 Axial Smoke exhaust roof fans for large distribution centers. In the event of a fire, these F400 axial fans can remove more than 2,750,000 m3 of smoke and heat from the building. This allows people to flee, the fire brigade can approach and fight the fire and the damage to the building is limited. These F400 roof fans are equipped with F400 self-closing shutters to prevent a cold fall when the fans are switched off. The fans and shutters are F400 tested and certified in accordance with EN12101-3 and suitable for extracting heat and smoke to a temperature of 400ºC for two hours.
