Plastic Cow House Exhaust Fan with 4 Blade

1. The double-layer hollow outer frame is made of polyethylene material, which is made by one-time rolling molding. It is durable, not easy to rust, and has the characteristics of corrosion resistance, safe insulation, vibration reduction and long service life.  
2. The fan blade adopts laser cutting technology, the new twist stamping stainless steel fan blade, large air flow, no deformation, no fracture, corrosion resistance, long service life.  The machine after dynamic balance detection and adjustment, vibration is small, stainless steel material can provide 410, 430, 304 and other materials for users to choose.  
3. It Equipped with high-performance pure copper core motor with 3C certification, aluminum shell, with corrosion resistance, heat dissipation, low temperature rise, high efficiency, customized bearing, longer service life.  
4. The pole of Fan, frame clip adopts galvanized plastic spraying double-layer anti-corrosion process, fasteners adopt hot-dip galvanized or Dachro process, better anti-corrosion.  
5. Add heavy front safety protection net, effectively protect the operation safety of the fan blade.
6. 6.Six strict testing procedures, noise detection, vibration detection, rotational concentricity detection, speed detection, air volume detection, machine efficiency detection.
