Swing drop hammer exhaust fan adopt advanced automatic manufacturing process, ensure the high accuracy while producing frames. And it is made of galvanized sheet, which has high resistance to corrosion.
The centrifugal exhaust fan consists of blades, motor, frame, protective net, supporting frame, shutter, centrifugal system and other components. The shutters are automatically opened after starting. After shutting down, the shutters are automatically closed to prevent outdoor dust and foreign matter from entering, and also to avoid the influence of rain and snow and downwind.
1.PVC Shutters, corrosion resistant, anti-aging.
2. The frame is designed according to the aerodynamic principle.
3.Equipped with FRP horn-cone, the exhaust performance is significantly improved.
4. It is made of high-strength anti-corrosion FRP material and has a thickened design, beautiful appearance, strong waterproof, corrosion resistance and strong aging resistance.
