Feature:

1.Outline adopt scientific bell design to achieve low noise, strong wind, strong effects of ventilation

2.Shutter introduce the principles of air downstream and synthetic PVC blinds, antioxidant, light weight, no deformation, flexible open and anti-air back.

3.High strength aliminum magnesium alloy hub with ribsm, it's light weight, high strength and good tensile

4.Using the imported bearing, high strength, low noise and durable

5.High performance energy saving fan motor located in the center of fan, small wind resistance, the structure is more reasonable

6.Wind capacity is 48000m3/h
