1.fan blade is special designed for top grade efficiency which made of stainless steel by punch forming. Large air volume, no deformation, no broken, no dust, attractive and durable. Thickness 1.2mm, surface finish BA grade.

2. Centrifugal system open the shutters at complete 90 degree to ensure the lowest air resistance and biggest air volume. When close, the sealing can efficiently block light and wind into the poultry farm house. As the first one adopt high quality nylon PA66 to ensure the long service life. The fasteners of centrifugal system all are copper rivets, wear-resisting and no rust, flexible. Guide rod is made of 304 stainless steel, ensures the high strength, no rust, reduces frication.

3.Belts are Japanese brand, ensure the long service life, maintenance free. From 2010 the first adopt Type B belt which is 3times longer service life instead of type A.
4.Both China famous motor and Siemens motor are available. Motor voltage and frequency can be customized. Chinese famous motor OEM by special design for fan, the first put in the phase lack protection device which would power off when shortage of electricity. Motor protection grade IP55, insulation class F grade.

5.Linking parts made of aluminum alloy, light weight, not deformation, and with wear-resistant shaft sleeve, reduce clearance, then reduce frication to ensure the shutters open flexibly. The spring is made of 304 stainless steel, long time use, no deformation, no rust.

6.Fan bearing adopts imported double-row bearing with special waterproof design, water can’t enter. High strength, lower noise, maintenance free and long service life.
