The PM motor all in one oil free scroll air compressor packages the scroll element, permanent magnet motor, 200-300 L air receiver, refrigerated dryer and filtration into a single cabinet. You connect power and pipe, and the unit delivers dry, 100% oil-free air at 0.8 MPa from 2.2 kW to 11 kW – the simplest way to install Class 0 air in a clinic, laboratory or food plant.
Key features
- Air receiver and dryer included. 200 L or 300 L tank plus refrigerated dryer inside the cabinet – no separate installation work.
- 100% oil-free Class 0 air. Suitable for direct contact with food, pharmaceuticals and breathing air systems.
- Permanent magnet drive. Z-P models use a PM synchronous motor for higher efficiency at partial load.
- Intelligent control panel. Pressure, temperature, runtime and alarm display in one interface.
- Small footprint. 1320 x 550 x 1550 mm for the 2.2-5.5 kW models, so it fits a service room or production corner.
- Quiet operation. Scroll compression with an acoustic cabinet keeps noise low enough for indoor installation.
