1、 Overview:

The DWT series roof fan adopts a molded axial flow or centrifugal impeller, a fan specific motor direct drive, an anti-corrosion wind cap, a metal or fiberglass wind duct base, and has the characteristics of corrosion resistance, light weight and high strength, smooth operation, simple maintenance, low noise, and excellent performance. It is widely used in various industries such as power generation, chemical industry, rubber, pharmaceuticals, food processing, metallurgy, and civil buildings for ventilation and air exchange.

2、 Type:

The DWT-I type adopts a wide blade, large chord length, spatially twisted inclined axial flow impeller, suitable for ventilation and air exchange in medium and low pressure, high flow situations.

The DWT-II model adopts optimized centrifugal impellers, which are suitable for exhaust and ventilation in high-pressure applications.

According to different usage environments and conveying media, impellers can be made of materials such as aluminum alloy, steel plate, engineering plastic, fiberglass, etc., and can be made into conventional, anti-corrosion, explosion-proof, and anti-corrosion explosion-proof types.
