Hengyuan Exhaust fan is made up of blade,motor,outer frame protecting nets ,supporting frame and shutters.it is made based on aerodynamic,effectively reduces the wind resisitance.The main parts are made of galvanized steel sheets and stainless steel sheets. The products are widely used in farms, greenhouse, workshops and warhouse.

1,The outline border adopts advanced automatic process, more accuracy,high zinc coated material.

2,The aluminum metal alloy of the high strength hub, adopts aviation aluminum magnesium metal alloy, light weight, high strength, good tensile.

3,Belt adjust automatically, no need manual adjustment during lifetime.

4, Shutter adopt special push-pull centrifugal device, ensure shutter totally open and close, windproof, rainproof and dustproof.

5, Newly punch forming fan blade, reasonable angel and reach the max. air flow, mini. Noise.

6,Double bracing (E style) belt transporter, Europe industry motor standard.

7, Safety net easily tears down.

8, Strictly quality test process: noise test, vibration test .concentric performance test, fan blade turning speed test, input air teat and vehicle efficiency test.

9,Special motor hole wind shield, avoid losing wind to reach the best wind suck effect.

10, belt type B,thicker and durable ,double life time.
