Material used in production ofAir cool industrial ceiling fan

the frame adopts advanced automatic process technology and galvanized sheet.

Thickness: zinc coating: 275g/m2

Top and bottom plate: 1.0mm

 Left and right plate: 0.8mm

 

Shutter
Material: hot galvanized plate.

Thickness: zinc coating: 275g/m2

Shutter:1.5mm

We have increased the weight of the machine for better stability. Make sure the shutter open in degree of 90 on the progress of the machine. Make sure the minimum resistance and maximum blast capacity. When the machine stops, the shutter could proof the sunshine and wind.

 

Blades

Material: adopts 430BA stainless provided by Krupps.

Thickness: 1.2mm

All flabellum passed the balance test to ensure the blast capacity. the accurate design of the angle could ensure the maximum blast capacity and minimum noise. 

 

Opening structure:

Material: 70 percents high strength nylon and 30 percents glass reinforced plastic. the rivet connection has good rust-proof effect. the guidepost adopts 304stainless steel to ensure the high strength and rust-proof. 

 

Linkage and spring

Material of linkage:  aluminum alloy (non-deformation);

Material of spring: 304stainless steel

 

 

Motor base

 

the improved base could fix the machine position better, and keep the small belt pulley and big belt pulley on the same line. by this way, the abrasion of the belt is reduced and the service life is longer.

 

the machine for different power is optional according to clients' demand.

 

the new bolt is easier to install.
