Refurbished dental air compressors · Southern California

A rebuilt compressor, sized to your operatories.

Oil-free and lubricated dental compressors from the brands we repair every week, rebuilt in our shop, pressure tested and installed in your equipment room. When a compressor dies, this is the fastest honest path back to running air.

Based in City of Industry. Equipment sales, delivery and installation anywhere in California; delivery and installation are quoted by distance.

In the shop now

Compressors in the shop this week.

Listed only once a unit is in our City of Industry shop, rebuilt and pressure tested. If a compressor is down today, call instead of waiting for a listing.

NOW

Ask for today's compressors

Compressors are the units practices need fastest, so they rarely sit. Call with the number of operatories and whether you need oil-free, and we will tell you what is here and what is coming through the shop.

What a refurbished compressor includes

The parts that wear are the parts that get replaced.

A used compressor is only as good as its heads, valves and dryer. We rebuild what wears, test it to its rated pressure and tell you the unit's history.

HDS

Heads, valves and motor

Compression heads inspected, valves and rings replaced where worn, motor and start components tested; lubricated units get fresh oil and filters.

DRY

Air dryer and filtration

Desiccant or membrane dryer serviced or replaced, intake and coalescing filters renewed, so the air at the chair is dry. Wet air is the number one cause of handpiece and valve trouble.

TNK

Tank and controls

Tank drained and inspected, pressure switch, check valve, safety valve and gauges verified, then the unit is run to pressure and held.

FIT

Sizing and installation

We match the unit to your operatory count and your room's power and ventilation, then install, pipe and test it, and show your team the drain and filter routine.

Not sure whether to repair the compressor you have? Start with the repair page; replacement is recommended only when the core is worn out or the unit is undersized.

Choosing a compressor

Four questions that decide the unit.

01

How many chairs at once

Compressors are rated by simultaneous users. Count the operatories that actually run together on your busiest day, not the rooms you own.

02

Oil-free or lubricated

Oil-free units are the norm in modern dental offices and need less routine attention; lubricated units are quieter and cheaper to rebuild. Both can be the right answer.

03

The dryer matters

A compressor with a tired dryer sends moisture to every handpiece. We treat the dryer as part of the unit, not an accessory.

04

Power and placement

Voltage, breaker size, ventilation and distance from the operatories all affect the install. We confirm them before the quote.

How a purchase works

From a phone call to a working operatory.

01 / 04

Tell us what you need

A chair for a new operatory, a compressor that died, a sterilizer for a second room. A brand or model helps but is not required.

02 / 04

We tell you what we have

What is in the shop today, what is being refurbished, and what we can source. Photos and the unit's history on request.

03 / 04

One written quote

The unit, the warranty, delivery and installation, each spelled out. Delivery and installation are quoted by distance from City of Industry.

04 / 04

Delivered and installed

Our own technicians deliver, connect, test and hand over the unit, and they are the same people you call for service afterwards.

Before you buy

Good questions. Straight answers.

Often, yes, if a suitable unit is in the shop. Call 626-422-2315 with your operatory count and voltage, and we will tell you what is available today and how soon it can be installed. For an office with no air at all, ask about emergency repair first.
The brands we repair every week: Air Techniques, Tech West, Jun-Air, Midmark and others as they come through the shop. We also sell new Tech West compressors if you would rather start fresh.
Yes. A compressor leaves our shop with its dryer serviced or replaced and its filters renewed, because dry air is the point of the unit.
Setting the unit, connecting it to your air line and power, checking the breaker and ventilation, running it to pressure, checking for leaks and showing your team the maintenance routine. Any electrical work your office needs is identified before the quote.
Yes. Equipment sales, delivery and installation cover all of California. Most of our deliveries are across Southern California, from Santa Barbara and Ventura counties down to San Diego and out to the Inland Empire. Delivery and installation are quoted by distance from our City of Industry shop, and the quote is in writing before anything is scheduled.
Yes. Every refurbished unit we sell comes with a warranty. The period depends on the equipment type and its condition, and the exact terms are written into your quote so there is nothing to interpret later.
No. We do not buy doctors' equipment and we do not take trade-ins. The units we refurbish come through our own channels, and we only list a unit once it is in our shop.

Ask about a unit
