Premium Compressed Air Stations: AIRCENTER

Quality doesn't need a lot of space

AIRCENTER stations by Kaeser provide their owners with complete solutions in premium quality. The rotary screw compressor with SIGMA profile, add-on refrigeration dryer and compressed air receiver ensure a straightforward compressed air supply for your facility. The SX, SM and SK series AIRCENTER feature these technical parameters:

  • Pressure: 8, 11 or 15 bar
  • Flow rate range: 0.26 – 2.55 m³/min

Our premium compressed air stations require little space and are the perfect solution for smaller industrial operations.

Your advantages

  • Space-saving integrated solution:
    Compressor, refrigeration dryer and air receiver take just one square metre with this system.
  • Protection from corrosion damage:
    Thanks to the integrated refrigeration dryer, the system delivers high air quality and protects your equipment from corrosion damage.
  • Fast installation:
    Simply connect this compact compressed air package to the power supply and compressed air distribution network. Compared to a conventional air station, you avoid major piping and installation efforts.

Profitable thanks to low life-cycle costs
