Corrosion resistance FRP roof mounted ventilation fan 


Product Description

Roof fan is a exhaust and exchange air equipment installed in the rooftop. Due to the particularity of installation environment, the fans have to use special material and construction. With the features of low noise, high efficiency, corrosion resistance, light weight, easy to install and compact structure. Divided into axial flow rooftop fans and centrifugal rooftop fans.

Roof fans can be divided into axial flow wind roof fans, centrifugal roof fans and motorless roof fans according to the different requirements of air volume, wind pressure and noise.

DWT-I axial flow roof fan is suitable for ventilation in medium & low pressure and large flow places such as warehouses, industrial and mining plants, power stations, stations and stadiums.

Technical Parameters
 1) Fixed installation angle 


2) Adjustable installation angle

Production Process


Advantage

1. High-efficiency, low-noise: This series uses CAD software, after optimizing design and research, its design has been rewarded patent of utility model and national outstanding patent. Its design adopts different rotate speeds, angles and impellers with the same diameter to satisfy different conditions. In this way, the fans match with the whole system and save energy and bring down noise.

2. Light, high-strength, corrosion-resistant: The impeller has different material types for various mediums, which encompasses ABC (engineering plastics), FRP (glass fiber reinforced plastics) and aluminum alloy sheet. 

3. Stable operation, long-term service: little inertia, precise balance, stable operation make the fan's performance standard higher than its competitors. 

4. Large applying scope: This series fans can be made into explosion-proof, retardant, anti-aging type, etc., for ventilation of the conditions of flammable, explosive and corrosive air.

5. Elegant appearance: The rain cover is made of FRP with external surface of imported resin film. Its curve is smooth, elegant and practical. It can also be modified by plastic sprayed (PVC) after galvanization.   

Application

The axial roof fan is widely used in warehouse, mining factories, power station, bus station, railway station, gymnasiums and so on.
