1.Introdution .

Roof fan’s main components take FRP materials, Impeller adopts a more advanced airfoil blades in some of the weight of the rotating parts, thus they can meet the requirements for aerodynamic performance . The outer surface of the membrane use gel coat resin, smooth surface, beautiful appearance, light weight, low noise, corrosion resistance but also a good flow vibration performance, stable and reliable operation of energy efficient explosion-proof characteristics.

4. Widely used in these places

1). Ware house ventilation ;

2). Factories and workshops (such as paper mill, galvanized products producing factories,

painting factories);

3). Garage and other buildings which need air ventilate.
