ANY AIR 2

01 · About MDX

A dental engineering
heritage.

×

MDMED has long been the foundation of Korea's dental chair and surgical table industry — a manufacturing expert in hydraulic systems (pumps, solenoid valves, cylinders) and dental apparatus (3-way syringes, HVE, saliva-ejectors). Most Korean dental chair manufacturers build on MDMED components. The trust runs decades deep.

MDX is MDMED's compressor and vacuum pump arm. Built on the parent group's precision-machining and quality-control discipline, we run rigorous in-house testing — every unit gets serial-tracked inspections, dedicated measuring equipment, and a balance of automated lines plus skilled manual labor.

ANY AIR 2 is the first product of this approach — a piston-type compressor that draws directly on MDMED's precision-machining know-how. AnyVac40 (vacuum pump) rounds out the line. Together they're our answer to the dental market's long-standing question: what would a serious Korean alternative to the European compressor majors look like?

01 · The Real Cost

Cheaper today.
Expensive tomorrow.

Most clinics buy rocking-piston compressors because the sticker price looks attractive. Two service calls in, the math flips. Here's the same machine — viewed through total cost of ownership, not the spec sheet.

* TCO (Total Cost of Ownership) — the real lifetime cost of a machine: purchase price plus maintenance, repairs, and downtime.

Rocking Piston

Wobble · Conventional Type

Hidden TCO

Rocking Type · How It Works

Seals and housing wear with every cycle. Output pressure drops gradually — most units fall below spec inside 12–24 months.
Sensitive to heat under continuous load. Exceeding duty cycle accelerates failure. Not built for back-to-back appointments.
Typical warranty: 1 year on the head. Repair costs and downtime erase the initial price advantage after one major service.

Articulated Piston

ANY AIR 2 · Connecting-Rod Type

Lower TCO

Articulated Piston · How It Works

Piston moves on a single vertical axis. Lateral wear is eliminated by design — output stays stable for years, not months.
100% duty cycle, validated to 5,000 hours continuous. Runs all day across multiple chairs without thermal derating.
5-year head warranty. The longest in the dental-compressor category. Backed by serial-number tracking and registered service.
Integrated cooler, centrifugal separator, HEPA + ULPA 16. Patient-side air is dry, oil-free, and 99.9995% particle-free.

5-Year Lifespan · Illustrative

Rocking Type

Output drops below spec; overheating risk climbs. It runs harder to compensate — typically past usable spec within 1–2 years.

Articulated Piston

Output holds. No wear-out, runs through heat — 5,000h / 100% duty cycle validated.

The bottom line. A rocking-type unit at $1,000 saves you money on day one. After one repair plus the downtime cost of a half-day clinic closure, you're already past the price of an AnyAir2 — and you still have a worn machine. Articulated isn't a premium upgrade. It's the breakeven choice.

02 · Engineering

Three
essentials.

AnyAir2 is built on 30+ years of MDMED precision machining.

01 / Piston Head

Articulated motion.
Dual cooling.

VERTICAL TRAVEL · OIL-FREE

5,000h

Continuous test passed

The piston is driven by a connecting rod and travels strictly vertically. Lateral wear — the failure mode that kills rocking pistons — is engineered out. External-fan air cools the head twice on its way through: once over the casing, once through the cylinder chamber.

02 / Air Quality

Triple filtration
at patient grade.

INTAKE → HEPA → ULPA 16

99.9995%

Of 0.1–0.3 μm particles removed

Compressed air ends up in the patient's mouth via the handpiece and 3-way syringe. Every breath through the system passes through three stages — intake debris, HEPA, then ULPA 16 — inside a precision centrifugal separator. No silica gel to manage.

03 / Tank & Drain

Stainless 304.
Hybrid discharge.

SUS304 · DUAL SOLENOID

5yr

Head warranty · 1 yr components

Steel tanks rust. Aluminum is better. SUS304 is the right answer for medical air — corrosion-immune, food-grade, decades of life. Paired with a dual solenoid drain system that actively pulls moisture out during AND after every cycle.

03 · Hybrid Moisture Discharge

Moisture doesn't
wait for maintenance.

The best dryer is membrane — and the most expensive. So many compressors use silica gel, which performs well by adsorption — until it saturates. Once saturated, dew point rises and water vapor passes straight through. Worse, if the desiccant isn't replaced on schedule the granules cake into powder that clogs solenoid valves and can eventually reach the compressor head itself.

AnyAir2 takes a different route. A centrifugal separator removes droplet moisture — nothing to replace, nothing to clog. Because separators work on droplets rather than vapor, a small amount of residual moisture still condenses inside the tank as pressure and temperature shift. So two solenoid valves run in opposite directions to handle it: one drains continuously while the compressor runs, the other when it stops. The tank stays light on water even when Friday's drain check gets skipped — and the SUS304 stainless tank doesn't rust regardless.

N/C · WHILE RUNNING

Tank Drain

Normally-closed valve at the tank base activates during operation — actively pushing condensate out as it forms.

N/O · AFTER STOP

Separator Drain

Normally-open valve at the dryer opens when the head stops — releasing moisture captured by the centrifugal separator.
