air vent fan

1.Automatic machine,, 2.Agriculture ministry test ,, 3.Good quality ,, 4.Big production capacity,, 5.Big wind volum - details see: https://www.machineto.com/air-vent-fan-10207440

Place of Origin:Shandong China (Mainland)

Brand Name:AONUODI

Model Number:JN

material of outside:galvanized

1.the outline border adopts advanced automatic process,material is galvanized plate, more accuracy and corrosion resistance.

2.The hub was made of aluminum magnesium alloy, light weigh, high strength and good tensile.

3.The stainless steel blades was made of in one time punch.the figure s angle is reasonable,so small noise and big wind capacity,the safety is very good.shutter adopt the mechanical weight balancing to close,open by the wind,and the shutter is wind-proof ,rainproof and dust proof.

4.Maintenance and disassembly is convenient.

5.The six strict quality inspection process: noise inspection,vibration test, concentric performance test,fan blades rotation test, wind capacity test and the efficiency test.
