THE INTERNATIONALSTANDERD  EXHAUST FAN JFD-1250HE MODEL (HIGH GRADE)

 1.OUTLINE BORDER    The outline border was one time punch by advanced automatic process, thicker zinc coat make it corrosive resistance. There are water holes on the bottom of the frame.

2.HUB  The hub was made of aviation aluminum magnesium alloy, hot casting molding, light weight, high strength, and good tensile.

3.BLADE  Six new design stainless steel blades were made in one time punch. No distortion, no fracture, attractive and durable. The figure’s angle is reasonable, so small noise and big wind capacity, the safety is very good.

4.  bracing (E style) belt transporter. High performance national standard fan motor with CCC certificate, the voltage is 380v. Protection class: IP55.  Insulation Class: F

5.shutter adopt the mechanical weight balancing to close .open by the wind,and the shutter is indproof,rainproof,anddustproof

7. BELT  Imported belt type B, no distortion and long work time, no need of maintain during whole life time.

8. ADJUSTER  Automatic adjuster with aluminum-magnesium alloy materials, abrasive molding frame, no deformation, long service life, the use of belt tension inside, effectively prevent reverse twist of belT

9. QUALITY INSPECTION  The six strict quality inspection process: noise inspection, vibration test .concentric performance test fan blade rotation test, wind capacity test and the efficiency test.
