High Efficiency Low Pressure Screw Compressor With Permanent Magnetic Motor



SKF bearing


Compared with bearings of other brands, SKF bearing, it has good abrasive resistance, superior fatigue resistance, strong corrosion resistance and comfortable muting property, making longer service life, higher reliability and lower noise of permanent magnet synchronous non-inductive motor.


Highly efficient magnetic steel of permanent magnetic motor


Punching uses high-performance low-loss silicon, we conduct simulation analysis of mechanical strength with finite element method so as to make rotator inertia reach the minimum on the condition that enough mechanical rigidity and mechanical strength.

Rotator magnetic steel adopts high-performance NdFeB permanent magnetic material to form sine wave air-gap field.

Axial flow uses the processing method of embedded bond, which simultaneously meets requirements of optical axis and bond axis.

1. Before quoting, what should users offer?
1). Discharge pressure (Bar, Mpa or Psi)
2). Air discharge/Air flow/Air capacity (m3/min or CFM)
3). Power supply (220/380V, 50/60Hz, 3Phase)
2. If I don't know the pressure and air flow, what should I do?
1). Take the picture of nameplate, we will advise the suitable air compressor to you.
2). Tell us what industry you are, we can advise the suitable one (so as to air tank / air dryer / air filters).
