exhaust fan

1.Fan blade is made of Krupp stainless steel by punch forming.No dust,attracrive and durable.The shape of special blade could ensure the large air volume,no deformation,no broken,make the air volume same all the way.

2.The Chinese famous motor and Siemens motor are available.The motor voltage and frequency could be customized.The Chinese motor which spcial design for fan,it is the frist one put forward the phase lack protection device which power off.When shortage of electricity,it could power off.Motor protection grade IP55,insulation class:Grade F.

3.The fan belt pulley is made of high strength aluminum-magnesium alloy by die-casting which reduces the weight of the exhaust fan blade,keep the blade and impeller complete,high corrosion resistance.To strengthen the pinch roller design,eliminate the internal stress,improve its own rigidity and stability,never broken.

4.The bearing uses double-row bearing with special waterroof design,water can not enter.High strength,low noise,maintenance free and long service life.

5.The centrifugal system open the shutter completely,ensure the lowest air resistance and biggest air volume.When it closed,it can efficiently block the wind,rain,dust.Use the high quality nylon 100% to ensure the long service life.The fasteners of centrifugal system all are copper rivents,wearing-sesisting and no dust,flexible.Guide rod is made of 304 stainless steel,ensuring the high strength,no dust,reduces frication.
