Fan blade:
It is made of aluminum and magnesium alloy extruded and stretched, and has the advantages of high strength, good toughness, light weight,long life and safe operation.The fan blade
surface is treated with T5+ bright surface oxidation treatment, which enhances the corrosion and oxidation resistance of the fan blade and can cope with special environmental operations.
When the fan blade is running, the air will generate vortex at the end of the aerofoil fan blade. The tail wing can eliminate this part of energy loss, stabilize the fan operation, and make the air flow more consistent with the aerodynamic principle.
