Advantages:

1) Energy saving

Take 54"type of fan for example, the power of general type of fan is 1100W or 1500W, but our fan is 750W. So if you take use of it, you just need pay half of the cost.

2) large air output

Take 54"type of fan for example, the measured air volume of better type of fan is about 40000 cubic meters, but our fan can reach to 58300 cubic meters.

3) lower noise

Our perfect design concept and material lower the noise, and it can work steady.

4) long lifetime

The fan casing is produced by the material of glass fiber reinforced plastics which is anti-corrosion and air-slake. The material of shutter is PVC which is air-slake. Fan blade is made of nylon and fiber material, have better sturdiness and flexibility.

5) Low failure rate

The electric motor and blade of fan are connected directly. The rotation speed of our motor is 450rpm which is half ordinary fan's, however, the rotation speed of ordinary fanalways reach to1450rpm for same air volume output.

If we regard our draught fan as a worker: He eat half of "meal", does one and a half workers "work", also he has good temperament, what is important is that he is strong, you don't have to pay too much extra expenses, he can work for you for very long time. So it has high efficiency.
