Product features:

The outer frame adopts advanced automatic processing technology, with extra thick zinc coating and strong corrosion resistance;

Aviation aluminum alloy wheel hub, light weight, high strength, good toughness, no fracture;

A new type of twisted stamping stainless steel fan blade, with reasonable blade angle, can not only ensure air flow impact, but also produce very low noise;

The shutter is opened and closed by a unique push open close mechanism, which ensures that the shutter is completely opened and closed, and the shutter is windproof, rainproof and dustproof;

Double support (E-type) belt drive, national standard, industrial motor with 3C certification;

The rear safety net is easy to disassemble;

There are 6 strict quality inspection procedures: noise detection, vibration detection, rotating concentric performance detection, blade speed detection, air volume detection, and overall efficiency detection;

The unique wind shield of motor hole can prevent the loss of air volume and achieve the best air collection effect.
