Permanent magnet variable frequency screw air compressor

  • Permanent magnet variable frequency screw air compressor1
  • Permanent magnet variable frequency screw air compressor2

The variable frequency air compressor can change the revolution of the main motor according to the air consumption accurately when the exhausting pressure is stable so as to achieve the purpose of energy saving. The system can realize remote and multiple units combined control, to achieve a comprehensive adjustment for the user, and save the energy much more. Especially when the user gas consumption range is larger, the better energy-saving effect.

1、Starting & Running The impact of the grid is small, after the starting to run and reach the rated pressure and the compressor will operate in the variable frequency mode.

2、Constant pressure air supply to keep the balance between air supplying & air consumption.

3、Excellent controlling system leads to safety protection function.

4、Using independent cooling fan motor,low temperature for running,longer service life.


The advantages of the servo permanent magnet motors:

• High efficiency 

• Simple structure

• Performance reliable
