DWT-I Series Axial Flow Roof Fan
Using wide blades with a large chord length and an inclined blade shape, the blades are formed by hydraulic pressing of aluminum alloy. The blades are riveted and assembled with a cross frame, and the impeller balance precision is no greater than G5.6 level. The blade shape can achieve the required air volume and air pressure at low speeds, reducing fan noise. Models above No. 12 can be made with adjustable blade angles to achieve energy saving and noise reduction.

DWT-II/III Series Centrifugal Roof Fans
Structural characteristics: The impeller uses a centrifugal impeller, suitable for places with small air volume but higher pressure. The II series adopts a double-layer air cap, while the III series has no air cap. The impeller material is made of steel or fiberglass, with a balance accuracy not exceeding G5.6 level. The steel casing is welded, while the fiberglass casing is formed in one piece.

RTC Series All-Aluminum Centrifugal Roof Fan
Structural characteristics: The design features a smooth appearance and fine craftsmanship. The direct-coupled motor is located within the airflow for adequate cooling, while the belt-driven motor is positioned on the side or top, isolated from the exhaust airflow. This design is more suitable for discharging polluted air containing smoke, oil mist, and humidity, thereby extending the lifespan of the motor and transmission components. It boasts advantages such as high pressure, moderate air volume, low noise, energy efficiency, and an aesthetically pleasing and sturdy appearance.

XBDZ Series Wall-Mounted Axial Flow Fan
Using wide blades with a large chord length and an inclined blade shape, it can achieve the required air volume and pressure at low speeds, reducing fan noise. The casing is square, with an inner layer that is circular, which further reduces fan noise. On the wall side, there are aluminum alloy rainproof louvers or self-closing louvers to prevent outdoor rainwater from backflowing indoors.
