Compressed Air System Basic Models: The SXC "Compact" Series


The all-in-one compact compressed air package

Compressed air systems (*) of the SXC series have been designed by Kaeser for trades and crafts. On only 0.62 m², they comprise all components necessary for air supply under a single strong polyethylene cover: a rotary screw compressor with SIGMA-Profile, a refrigeration dryer and an air receiver.

Compressed air systems of the SXC series are offered with these performance data:

  • Pressure: 8, 11 or 15 bar
  • Flow rate range: 0.26 – 0.80 m³/min

Your advantages

  • Connect and go:
    Piping and installation of our integrated packages takes little time. Simply connect this compact compressed air package to the power supply and compressed air distribution network and you’re ready to go - that’s it!
  • Protection from corrosion damage:
    Thanks to the integrated refrigeration dryer, the SXC package delivers high air quality and protects your tools and equipment from corrosion damage.
  • Simple maintenance:
    All maintenance and service points are easily accessible once the SXC’s removable enclosure which is made of rotational moulded polyethylene is effortlessly lifted away. The electronic condensate drain can be inspected via a grille. Maintenance is simple and effective.

* This dryer series contains fluorinated greenhouse gases. All models contain refrigerant R-513A (GWP 631).
