FAQ

What is the difference between the ARB CKMTP12 and CKMTA12?

The CKMTP12 is the portable version of ARB's twin-motor compressor system. It comes assembled in a carry case with an air tank, 20-foot hose, battery connections, tire inflation equipment, and other accessories. The CKMTA12 is intended for permanent onboard installation.

Is the ARB CKMTP12 good for large off-road tires?

Yes. Rapid inflation of large off-road tires is one of the primary applications for the twin-motor portable compressor. Its 100% duty cycle also makes it well suited for airing up multiple tires after a day on the trail.

Does the CKMTP12 need to be permanently wired into the vehicle?

No. The portable system includes a wiring loom with automotive-grade battery clamps, allowing it to connect directly to a compatible 12V vehicle battery without a permanent compressor installation.

Does the ARB portable twin compressor include an air tank?

Yes. The supplied CKMTP12 package includes the compressor and air tank assembled inside the carry case along with the hose and inflation accessories.

Can the ARB CKMTP12 operate Air Lockers or air tools?

The compressor can support ARB Air Locker operation when equipped with the required optional accessories. The included air tank also allows the system to support compatible air-tool applications, but tool air-consumption requirements should be checked before use.
