3.Adapt to harsh environments,effectively resist fast transients,electrostatic discharge antiinterference,surge discharge anti-interference,avoid conduction interference,shield electromagnetic,power grid,high temperature.The protect grade up to IP55.
4.Pass EMC,CCC and electric-protection test.
5.Get UL,EMC,LVD,ROHS.

Blades- Airflow components

1.Blade design-Streamline variable cross-section
Conform to aerodynamic equal chord length theory,combined with the relative linear velocity principle,the blade narrows（304-186mm) and thins(43mm-21mm) from root to tip till tail then widen,the air is more even and uniform.
2.Blade material-Aviation aluminum alloy
1.5mm thickness No.5052H32 aviation aluminum alloy original plate,precision CNC molding,high strength and flexibility ensure the blade not to be broken.
3.Blade weight-More lighter and safer
6.7kg per blade(24ft),less blades,lighter weight,it can reduces the motor load,prolong the life,more safe and cost-efficient.

HUB

1.More mechanical properties:6061T6 aviation aluminum,perfect appearance and metal streamline to ensure the mechanical performance.
2.More precise dynamic balance:After CNC machining,max tolerance is 100μm to ensure the dynamic balance.

Mortise and tenon connection

Full mortise and tenon connection to ensure the fan’s safety.
1.Motor and hub:The inner and outer cone are firmly connected, forms self-locking to prevent falling.
2.Hub and petiole:The petiole and hub hook connected ,the bolt not stressed to ensure strength.
3.Blade and petiole:Centrifugal,resistance and buoyancy transfer to chassis by concaveconvex connection to avoid the fracture.
