Two stage compression screw air compressor reduces the compression ratio per level,reducing internal leakage and increase the volumetric efficiency,reduces the bearing load,improve the working life of the host.Two stage compression instead of single stage compression,nearly a 15% increase in displacement,can realize a 15% more energy saving effect.

The 37kw permanent magenta variable frequency compressor is high-efficiency save power machine.It is designed in the FEM strength analysis to ensure the stability and reliablility of each part,and to realize long term operation with no faults,low noise and long life.

22kw two stage PM VSD screw compressor using large motor to reduce the unit speed, full load speed in the 2000RPM is a more quiet guarantee. The new air duct structure design, so that the whole air duce pressure difference, the structure is more beautiful.
