isipatented designed centrifugal system which can open and close automaticlly ,ensuring the shutter opens 90 degree under all the condition. And uncontrollable air can prevent from going into the birdhouse when the shutter works.
Mirror designed and injection moulding Stainless steel balde,with big air volume,never distortion and broken
experiment of homeostasis make the blade work smoothly,nearly no noise and steadily output of air
centrifugal shutter system made of high quality engineering nylon ,high strength and long service life
high efficient and energy-saving motor with ccc certificate ,protection class:IP55,insulation class:F grade

1.Centrifugal System. Special shutter pushing device which could open and close shutter automatically.
2.Stainless Blade. Punch forming stainless steel blades, no breaking, elegant appearance and durability.
3.Flame. Galvanized or aluminum outer frame, dustproof,waterproof,rustproof, beautiful appearance.
4.Motor. High efficient and energy-saving motor with National CCC Certification. Protection grade: IP55; Insulation grade: Grade F.
5.Open System. 100% raw material injection production of strong toughness nylon to achieve high strength and long service life. The steel parts embedded in guide rod are installed on flange, which improves the workability and avoids the telescopic variation of nylon during production.
6.Test. Calibrated by high-accuracy dynamic balance tester, ensure the stable operation of the fan, reduce noise, and extend service life.
7.Belt Pulley. The V-type belt pulley is cast with high intensity aluminum-magnesium alloy, with light weight and high strength.
8.Belt. We could manufacture Type A or Type B belt upon sales situation of dealers, and meet demands of different customers efficiently.
