Passat series
3-stage air-cooled starting-air compressors
Unmatched reliability, operational efficiency, easy maintenance: these benefits have made Sauer’s Passat 3-stage air-cooled compressors best sellers for years. By combining 3-stage compression with air cooling, the Passat compressors enable low compression temperatures – and those three benefits.
- Long maintenance intervals thanks to high-performance valves
- Minimal vibration through W-shaped 3-cylinder compression
- Rotating parts protected as fan wheel is directly installed on crankshaft
- Integrated condensate filter after second stage
- Reliable pressure oil lubrication through direct-drive gearwheel pump offering external access
- Attached final separator with automatic drainage and flexible mounting included as standard
- Safe operation and low maintenance thanks to integrated flexible coupling
- Safety valve, thermometer and pressure gauge monitoring for all stages: lubrication oil pressure and compressed air outlet temperatures monitored as standard
