PM VSD Screw Compressor — Single Stage

A PM VSD compressor (Permanent Magnet Variable Speed Drive) uses a permanent magnet motor that automatically adjusts the speed to match compressed air demand in real time. Instead of running at full capacity and venting excess pressure, the compressor delivers exactly the amount of compressed air needed — which can reduce electricity costs by up to 35% compared to traditional compressors.

The closed-loop vector control provides a response time of under 50 milliseconds with constant pressure regulation within ±0.1 bar. UH-series magnets withstand temperatures up to 180°C and have a lifespan of over 40,000 operating hours. Direct-driven 1:1 transmission eliminates energy losses and maintenance-intensive belts, while SKF bearings and 304 stainless steel piping ensure long service life.

The model range spans from 5.5 kW to 400 kW with working pressures between 7.0 and 12.5 bar, covering everything from smaller workshops to large industrial facilities. IP65 protection on models up to 45 kW and IP55 from 55 kW upward makes them suitable for demanding operating environments.
