Permanent Magnet Screw Air Compressor

Permanent Magnet Screw Air Compressor

The Permanent Magnet Screw Air Compressor combines a high-efficiency permanent magnet synchronous motor (PMSM) with a rotary screw airend for industry-leading energy performance. The PMSM motor achieves IE4 Super Premium Efficiency class, significantly exceeding standard induction motors across the entire speed range.

The integrated variable speed drive (VSD) continuously adjusts motor speed to match actual air demand, eliminating unload cycles that waste energy in fixed-speed machines. Energy savings of 30–50% compared to conventional fixed-speed compressors are achievable in applications with variable demand.

Available in a wide power range with direct drive coupling (no belt or gear losses), integrated aftercooler, air-oil separator, moisture separator, and microprocessor controller with real-time monitoring.
