This revolutionary rotary screw air compressors bring together an integrated systematic optimization of the compressor unit, an advanced permanent-magnet motor, and Kaishan SKY technology to achieve outstanding energy efficiency.

Rare earth material technology gives the permanent-magnet synchronized motors higher possible rotating speeds, wider operating parameters, and increased energy efficiency. Within their wide operating speed range, the Permanent Magnet Variable Frequency rotary screw air compressors are able to maintain extremely high motor efficiency compared with those using conventional drive motors.

The fully enclosed oil-cooled Permanent Magnet motor generates very little heat, resulting in a longer life. No cooling fan means significantly lower noise and less fan drag compared with conventional motors.
