Industrial Exhaust Fan/cooling Fan

Salient Features of industrial exhaust fan/cooling fan :
1.The frame material is galvanized with advanced auto-machining technique. Galvanizing layer 160g/a .The frame is pressed with flower pattern ,which promotes the intension and toughness of the frame.
2.It used Al-alloy rim ,so it has light weight ,high intension and good toughness.
3.Being imported from French Original ,the bearing is of high intension and durable using term without any noise.
4.Safety net with easy disassembly is convenient for maintaining.
5.High precision system is assistant by computers, which maximizes the effectiveness of the fan. Ten strict procedures that consist of airflow test, noise test, libration test, drive concentric test, blade RPM test, electric current test and whole machine efficiency test, dynamic balance test, the thickness of the galvanized sheet test, the size of the spare parts test, They assure the quality of the fan.
6.The guarantee period is one year, during which the easily damaged parts are offered free of charge.
7.Shutter is opened by this special automatic centrifugal open system, solving the problem that the shutter cana t open completely because of the impurity with the impurity with the Heavy hammer-type.
8.Motor be specially used for high-performance fan, with updated design for automatic regulating device, the belt doesna t need manual adjustment.
