1. Preferred materials, earthquake resistance and fall resistance
2. Explosion proof motor, aluminum alloy fan blade, long service life
3. The protective net cover is safe and durable
4. Stable performance and security defense
5. Compact structure and less land occupation
6. Reasonable appearance and structure, practical and convenient operation

FRP ROOF FANS:

1.DWT low noise roof fans takes CAD simulation optimization design, has high efficiency, low noise, stable operation, nice looking, anti-corrosion, explosion proof, etc. advantages.

2.This series products could be widely used for air circulation and air exhaust in generating, chemical, rubber, pharmacy, food processing, metallurgy etc. industries and senior civil buildings. 3.According to different operating environment and conveying medium, wind cap and drogues could be made of steel sheet or glass fiber, impeller could be made of alumel, steel, glass fiber, engineering plastics etc material.

SORTS:

Type DWT-1 is axial flow roof fans, could be used for air supply and air exhaust with low medium voltage and large flow.

Type DWT-2 is centrifugal roof fans, could be used for air exhaust with high requirements about voltage.

Type DWT-3 is centrifugal axial flow roof fans, could be used for special air exhaust in the special condition.

Type DWT-4 is non-motor roof turbine air exhausters, widely used for air exhaust and circulation in commercial buildings and factories and mines. It has no electricity, no noise, small capacity, light weight, high efficiency of air exhaust, easy installation etc advantages.
