Product Details

	Outer frame:using the standard galvanized sheet, the pressure muscle strengthen design with once ramming formation; standardly produced by advanced rivet craft assembly line;stable performance,can compared favorably with the import product.
	Shutter: having two kinds for choice: zinc plate and stainless steel plate. Characteristics: good rust prevention, sealing , lightproof.
	Shutter linkage: made of new nylon material, supporting linkage system,closing and opening shutters rapidly and swiftly. Width:400mm, increasing the loading capacity.
	Automatic opening system: the transmission belt uses automatic tight system, won’y relax, fall from the belt,operated simply. The heavy hammer institution utterly guarantees the shutter open and close safely, avoiding the loss of wind volume caused by shutter opening not to 90°.
	Bearing: same as that in car wheel, high intensity and duration.
	Wheel and blade base: made of magnesium alloy, using a stamping molding process, light weight, fine performance,stable running.
	Motor: Exported; protect level: IP5.5 Insulation degree: F.

Performance and characteristic:

Frame using advanced automatic processing,high precision.strong corrosion resistance with zinc coating.High-strength aluminum alloy casting wheel, the reasonable perspective of the type, to research the maximum air flow. High precision micro-computer-added manufacturing can make the best of its fan.

Five rigorous quality testing procedures: noise detection, vibration testing, concentric rotation performance testing, speed of blade testing and the whole fan efficiency detection.

380V special motor, CAD/CAM optimizing design.

The best choice of ventilation and cooling the temperature in the factory and greenhouse.
