Compressed air station standard models: The SXC Compact series


Compressed air stations with integrated refrigeration dryer and air receiver

Compressed air stations (*) from the SXC series have been especially designed by KAESER for trades and crafts applications. Featuring a footprint of just 0.62 m², they combine all of the components required for a compressed air supply beneath a single, durable polyethylene enclosure: a rotary screw compressor with the SIGMA PROFILE, a refrigeration dryer and an air receiver.

Compressed air stations from the SXC series are available with the following performance specifications:

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

Your benefits

  • Plug and play:
    Our all-in-one compressed air systems require minimal effort when it comes to piping and installation. Simply connect the station to a power supply and your compressed air network and that’s it – you’re ready to go!
  • Protected from corrosion damage:
    Thanks to the integrated refrigeration dryer, SXC systems deliver high-quality compressed air that protects your tools and equipment from corrosion damage.
  • Simple maintenance:
    All maintenance points are easily accessible by lifting off the lightweight, removable enclosure constructed from rotomoulded polyethylene. 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).
