Performance and characteristic
1.Patented designed centrifugal system which can open and close automatically ,ensuring the shutter opens *0 degree under all the condition .And uncontrollable air can prevent from going into the birdhouse when the shutter works.
2.Mirror desifned and injection moulding Stsinless steel balde ,with big air volume ,never distortion and broken.
3.Experiment of homeostasis make the blade work smoothly ,nearly no noise and steadily output of air
4.Centrifugal shutter system made of high quality engineering nylon ,high strength and long service life
5.High efficient and energy-saving motor with ccc certificate ,protection class:IP*5,insulation class :Fgrade
Parts in detail
1.MuHe 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.
2.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 IP*5, insulation class F grade.
3. Centrifugal system open the shutters at complete *0 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 PA*6 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 **0 stainless steel, ensures the high strength, no rust, reduces frication.
4.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.
5.Beltsare Korea Dongil brand, ensure the long service life, maintenance free. From ***0 the first adopt Type B belt which is 3times longer service life instead of type A.
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.
