Double Shutter Exhaust Fan

Performance characteristics:

1 Left frame adopts advanced automatic processing, hot galvanizing layer thick, strong corrosion resistance

Has high precision microcomputer aided manufacturing system can make the fan for the maximum efficiency;Eight strict quality

2  testing procedures: noise test, vibration test, static balance and dynamic balance, rotary concentric performance detection, wind speed detection, the machine detection efficiency

3  Derive new distortion of stamping forming blade, its reasonable blade Angle, can make the air flow to achieve the best level

4  Derive the blinds open adopt unique opening and closing mechanism, to ensure that the shutter opens and closes, completely after the shutters closed against foreign bodies, rainproof, dustproof, the role of the downdraft

5  Filled with iron set wind machine, glass fiber reinforced plastic wind device, ABS engineering plastics set ventilation (three) at the back of the net disassemble;CAD design optimization
