galvanized box fan agriculture fan draught fan

Working Principal:

Use the principle of negative pressure cross-ventilation, to bring the fresh air in from the opposite of the installation position——door or window naturally, and extract the indoor hot gas rapidly.Any improper ventilation problem can be solved. The cooling and ventilation efficiency can reach as high as 90%-97%.

Product Characteristics:

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.

9.Handler. Special recessed transportation handler design, convenient for loading/unloading and transportation, meanwhile, it will not influence the installation and visual appearance of the fan.

10.CAD/CAM design. Adopt CAD/CAM design, low investment cost, low consumption, high efficiency.
