AirStar 70

  • 100% Oil-Free, Revolutionary Compressor with Membrane Dryere Technology
  • Air Techniques was the first major U.S. dental company to introduce oil-free compressors with desiccant drying over 40 years ago and is now the first and only dental company using Membrane Dryer Technology.

  • Air Techniques Standards - Far And Above The Rest
  • Specialized engineers put every AirStar Compressor – constructed from parts made in our 200,000 square foot facility – through rigorous and repetitive testing at our in-house laboratories.
  • Improved intake filters, new purge muffler design, shock mounts and flat frame reduce vibration and noise
  • Only a single, annual filter change – no need to constantly monitor your system

  • First Things First
  • Air provided by every AirStar equipped with a Membrane Dryer is quadruple filtered – once at the compressor head, twice at the dryer and again as it leaves the tank – to ensure it is cleaner and drier than ever before.
  • A low-pressure dew point – less than that required by NFPA standards – eliminates damp conditions and lowers humidity levels.
  • AirStar stores compressed air at a humidity level of about 20% – significantly lower than hazardous
  • Sized for your practice, Compact shape for space saving installation
  • From design to install, Air Techniques is there every step of the way.
