THE INTERNATIONAL ADVANCED EXHAUST FAN JFD-1250E 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. Shuttermade of high strength hot dip galvanized sheet, the special shutter automatically open device (special push-pull device), ensure to open and close completely, so the shutter can open 90°at any times and windproof, rainproof and dustproof.

5. PUSH PULL DEVICE The push pull device adopts excellent toughness industrial nylon which is made of injection molding, high strength and long life. Guide bar mounted within the metal, increasing the strength of the guide bar and enhancing the reliability of opening and closing mechanism to make it service life.

6.MOTOR Double bracing (E style) belt transporter. High performance national standard fan motor with CCC certificate, the voltage is 380v. Protection class: IP54. Insulation Class: F

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.
