Shop air compressor with tank and dryer: AIRTOWER


The all-in-one compact compressed air package

If you're like most shop air compressor owners, you need a reliable source of clean, dry air that you don't have to think about on a daily basis. You have enough to do without designing and installing a new compressed air system. That's why KAESER offers the AIRTOWER—a more affordable but rugged shop compressor for any light industrial application including woodworking, machine shops, metal fabrication, and all sorts of vehicle maintenance and repair. The AIRTOWER is a quality alternative to piston and light duty rotary screw compressors.

AIRTOWERS are completely assembled and their compact design saves you precious floor space. They arrive ready for installation, saving you a lot of time and expense.

  • 3 to 7.5 hp
  • Pressure: 125, 155, and 217 psig
  • Flow rate range: 9 to 28 cfm

Your advantages

  • Ready to run:
    Install an AIRTOWER in no time at all. Simply connect to the power supply and compressed air distribution network and that's it—you're ready to go!
  • Protection from corrosion damage:
    Thanks to the integrated refrigerated dryer, the AIRTOWER package delivers a reliable supply of dry air that protects your tools and equipment from corrosion damage.
  • Simple maintenance:
    All maintenance and service points are easily accessible after removing the lightweight roto-molded polyethylene enclosure. The electronic condensate drain can be inspected via an opening on the cover.
