Product Description

Structure and Principle

Big cubic series High class fan is a mainly made up of blade,motor,outer frame protecting nets,supporting frames,shutters.It is made based on aerodynamic,effectively reduce the wind resistance.The major parts are made of galvanized steel sheets and stainless steel sheets.All the produces are widely used in various types of

farms,greenhouses,factory building.

Fan blade is made of Krupp stainless steel by punch forming,no dust,attractive and durable.Special blades shape design ensure large air volume,no deformation,no broken,keep air volume same all the way.

Both Chinese famouse motor and Siemens motor are avaiable.Motor voltage and frequency could be customized.Chinese famous motor,special design for fan,the first one put forward the phase lack protection device which could power off when shortage of electricity.Motor protection grade IP55,insulation Class:Grade F.

Fan belt pulley is made of high strength aluminum-magnesium alloy by die-casting which reduces the weight of blade impeller complete,high corrosion resistance.Special three reinforced rids pulley design.Blast standing treatment for attractive appearance,eliminate internal stress to improve its own rigidity and stability.
