Be different from belt drive system,which is due to the wear and slip of belt reduce efficiency and increase energy consumption,Huade direct drive system is to ensure high efficiency of energy transmission and constant flow output.

Huade PM VSD screw air compressor use protection level IP54 permanent magnetic motor, easy maintenance. Ulitimate temperature for magnetic loss is above 180℃， higher efficient than open-type protection level IP23.

Dobule stage compression structure, more energy saving. The core is the two-level compression of the injection screw air compressor in same power than single-stage compression of the injection screw air compressor and more 12%-23% air volume.
