Product details & specifications
Refurbished Air Techniques AirStar 70 Dental Air Compressor (AS70)
The Air Techniques AirStar 70 is the large-practice member of the AirStar oil-free compressor family, built around three 1.5 HP twin-cylinder oil-less compressor heads and a 30-gallon receiver tank that together support up to 10 simultaneous users. Its integrated membrane dryer and quadruple filtration system deliver ultra-dry, 100% oil-free air straight to your handpieces and delivery units, protecting turbine bearings and air-driven instruments from the moisture and oil carryover that shorten their service life. This AS70 has been professionally refurbished, cleaned, and function-tested by ABC Dentalworks and is palletized and ready to ship.

Why Practices Choose the AirStar 70
- Built for larger offices. Three heads and a 30-gallon tank carry up to 10 operatories without the pressure sag undersized compressors produce during peak hours.
- 100% oil-free air. No oil carryover into your air lines, handpieces or a patient’s mouth, and no oil changes to schedule.
- Membrane drying with quadruple filtration. Ultra-dry air protects turbine bearings and prevents the moisture that promotes bacterial growth in dental air lines.
- Fast recovery. 40-second recovery from 85 to 115 PSI keeps up with simultaneous chairs, hygiene columns and lab air.
- Continuous duty. Rated for a 100% duty cycle, with annual filter service as the primary maintenance requirement.
- Staged load. Heads stage on and off with demand, so the unit runs quieter and draws less power than a single large pump.
Refurbishment & Testing
Before this AirStar 70 was listed, ABC Dentalworks completed a full refurbishment and bench inspection covering the air receiver tank and safety valve, membrane dryer and filtration stack, coalescing filter and moisture management system, pressure switch cut-in/cut-out settings, regulator and gauges, cooling fans, compressor head performance, and the complete electrical system and control cabinet. The unit was then cleaned, cosmetically prepared, run-tested as a complete system, and palletized for freight. Refurbished equipment may show minor cosmetic signs of previous use — the photographs on this page show the actual unit and its actual condition.
Warranty
This AirStar 70 is sold with a 6-month parts warranty and a 90-day labor warranty from ABC Dentalworks. Full terms are on our warranty policy page. Equipment is not covered by the sealed-parts return rule that applies to replacement components — call us before you order if you have any question about coverage.
Shipping & Installation
This compressor ships by freight on a pallet; freight is quoted separately after checkout so you are charged the real rate to your address rather than a padded flat fee. Liftgate and residential or limited-access delivery can be arranged — tell us at checkout or call ahead. Installation should be performed by a qualified dental equipment technician. We ship nationwide from Florida.
Before You Purchase
The AirStar 70 requires a dedicated 208–230 volt single-phase circuit rated for its 24.0 amp full load. Please confirm your electrical service, mechanical room clearance and air line sizing before ordering. If you are replacing an existing AirStar 30 or AirStar 50, the AS70 will typically drop into the same footprint class but draws more current — verify the breaker first.
Frequently Asked Questions
How many operatories will an AirStar 70 run?
Up to 10 simultaneous users. Air Techniques rates the AS70 for large practices; if you are running 11 or more chairs plus heavy lab demand, step up to an AirStar 100 or run two units.
Is the AirStar 70 oil-free?
Yes. All three heads are oil-less, so there is no oil in the air stream and no oil to change.
Does it include a dryer?
Yes — the AS70 uses an integrated membrane dryer with quadruple filtration, delivering a dew point below NFPA requirements.
What power does it need?
208–230 VAC, single phase, 60 Hz, 24.0 amps full load on a dedicated circuit.
What is the difference between the AirStar 70 and the AirStar 50?
The AS50 uses two heads with a 20-gallon tank for up to 7 users. The AS70 adds a third head and a 30-gallon tank for up to 10 users and faster recovery.
Is this the exact unit in the photos?
Yes. Serial number 702253, manufactured August 2007. What you see is what ships.
