The DWT series roof fans utilize die-cast axial or centrifugal impellers, featuring direct drive from a dedicated motor, corrosion-resistant cowls, and metal or fiberglass windpipe bases. They are known for their corrosion resistance, lightweight yet high strength, smooth operation, easy maintenance, low noise, and superior performance. They are widely used in industries such as power generation, chemical, rubber, food processing, metallurgy, as well as ventilation and air exchange in high-end residential buildings.

The DWT-I model features wide blades, long chord lengths, and a spatially twisted inclined axial flow impeller, suitable for ventilation and air exchange in medium and low-pressure, high-flow applications.

The DWT-II model utilizes an optimized centrifugal impeller, suitable for exhaust ventilation applications with higher pressure requirements.

According to different application environments and conveying mediums, impellers can be manufactured from materials such as aluminum alloy, steel plate, engineering plastics, and glass fiber reinforced plastics, and are available in standard, corrosion-resistant, explosion-proof, and corrosion-resistant explosion-proof types.

Optional Accessories: Available with gravity-check valves (or electric type), bird/pest-proof nets, service switches, centralized control cabinets, and other accessories as required.
