ARB CKMTA12 Twin Air Compressor
Airing down for a beach or unsealed track is the easy half of the job — getting all four tyres back to road pressure afterward is where a weak compressor turns a five-minute job into twenty. The CKMTA12 is ARB's answer to that second half.
Key features
- Twin-motor design, 174 L/min maximum airflow
- 56A maximum current draw
- Pressure-switch controlled manifold, 135-150psi
- Sealed housing rated for dust and moisture resistance
- Heavy-duty cylindrical roller bearings
- Engineered and dyno-tested in Australia, 2-year warranty
RV use case
This suits owners who regularly air down for beach driving, unsealed roads or remote touring and want reinflation speed to match — rather than standing at each wheel for several minutes with a slow single-motor unit.
Pros
- Genuinely high airflow for a 12V unit, noticeably faster reinflation than a basic single-motor compressor
- Sealed, dust and moisture-resistant construction suits harsh touring conditions
- Australian-engineered and tested, backed by a real warranty
Cons
- 56A draw is substantial — needs properly rated wiring and a healthy battery, not a casual plug-in accessory
- Twin-motor design has a larger mounting footprint than a basic single compressor
- This is a genuine 4WD-grade unit — more capability, and cost, than an occasional tourer strictly needs
Best for
Owners regularly airing down and back up for unsealed roads, beach driving or remote touring, who want compressor speed that matches a set of rapid deflators on the way back up.
Verdict
More compressor than a once-a-year tourer needs, but for regular unsealed-road travel it's a serious, properly engineered upgrade that earns its keep.
