The fan mainly consists of blade,motor,frame,protect net,bracing cage and shutters.The motor drives bladeto cause air flow and louver window can open and close automatically to keep the dust from entering.
Performance characteristic:
The frame uses the advanced processing,high precision.Extra-depth zinc coating frmae,corrosion resistance strong.High-strength aluminum alloy casting wheel,the reasonable perspective of the type,to reach the maximum air flow.High-precision-micro-computer-aided manufacturing system can make the best of its fan.
Five rigorous quality testing procedures:noise test,vibration test,concentric rotation performance test,speed of blade test and the whole fan efficiency test.
