Anti-corrosion axial flow roof ventilation fan


Roof fans are exhaust and exchange air equipment installed on the roof. Due to the particularity of the installation environment, the fans have to use special materials and structures. It has the characteristics of low noise, high efficiency, corrosion resistance, light weight, easy installation and compact structure. Divided into axial flow roof fan and centrifugal roof fan.
According to the different requirements of air volume, wind pressure and noise, roof fans can be divided into axial air roof fans, centrifugal roof fans and non-motor roof fans.
The DWT-I axial flow roof fan is suitable for ventilation in low to medium pressure and high flow places such as warehouses, industrial and mining plants, power stations, stations and sports stadiums.
