 Fan blade of exhaust fan:

Runde fan blade is special designed for top grade efficiency which made of Krupp stainless

steel by punch forming. Large air volume, no deformation, no broken, no dust, attractive and

durable.Thickness 1.2mm, surface finish BA grade.

Centrifugal system of exhaust fan:

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, ensure the high strength,

no rust, reduce frication.

Belts of exhaust fan:

Belts are Japanese Mitsubishi brand, ensure the long service life, maintenance free. From

2010 the first adopt Type B belt which 3 times longer service life instead of type A. 

Fan belt pulley and flange of Exhaust Fan:

Fan belt pulley and flange are made of high strength aluminum-magnesium alloy by die-casting.

Light weight, lower vibration. Blast-sanding treatment for attractive appearance, eliminate

internal stress to improve its own rigidity and stability. 

Motor of Exhaust Fan:

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.

Linking parts of exhaust fan:

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.
