Mainframe adopts large rotors, low speed design,high efficiency, low noise,low vibration,high reliability, small compression ratio, small leakage and high cubage efficiency. 

Main motor was carefully selected an IP55 high-efficiency energy saving permanent magnet motor,which is according to the application needs of air compressor. It’s all reached the international first-class energy efficiency standard. Torque and loading can meet special design standards to optimize motor efficiency and power coefficient under load conditions. Comparing to other motors, the optimized coefficient efficiency is about 5%-8%.
