37KW 50HP Permanent Magnet VSD Screw Air Compressor
Our 37KW 50HP PM VSD screw air compressor is energy-saving industrial rotary screw compressor for continuous stable compressed air supply. Permanent magnet variable frequency start automatically adjusts motor speed according to actual air consumption, saving more power than fixed speed machines. Direct coupling structure reduces power loss, air cooling design easy to install and maintain.
