Aluminum Alloy Material Adjustable Angle Fan Blades
1.Typical Feature and Application
The adjustable fan blades are made of lightweight and high-strength materials, featuring both durability and corrosion resistance.
The adjustable-angle fan blades support multi-angle adjustment, precisely optimizing the air supply efficiency.
Aluminum alloy fan blades have excellent anti-oxidation performance and are suitable for various complex environmental requirements.
The surface of the fan blades has undergone fine treatment to ensure that they do not deform or fade over long-term use.
Customized fan blade solutions can meet the air volume control requirements of different industries.

3.Quality Control Plan for Aluminum Alloy Fan blades
Raw material inspection: Strictly screen aluminum alloy plates to ensure that the material strength and corrosion resistance meet national standards.
Process control: Precision die stamping is adopted to ensure the consistency of the arc and Angle of the fan blades.
Dynamic balance test: Each fan blade is calibrated by a high-speed dynamic balancing instrument, with a vibration value of ≤0.5mm/s.
Aging test: Sampling is conducted for 1000 hours of durable operation to ensure a service life of ≥10 years.
4.Blade Maintain
Regularly clean the fan blades to remove surface dust and oil stains and maintain efficient operation.
Check the fasteners of the fan blades to ensure that the bolts are not loose and prevent them from falling off during operation.
Observe the condition of the fan blades. If deformation or corrosion is found, they should be repaired or replaced in time.
During operation, monitor the fan blades. If any abnormal noise or vibration occurs, stop the machine immediately for inspection.
Avoid overloading the fan blades, adjust the rotational speed reasonably, and ensure stable operation.
5.Packing Detail
Plywood Box Packing: more safe packing, it is suggested when order is not enough one full container.
