ARB Twin Motor Onboard 12V Air Compressor (CKMTA12)

ARB Twin Motor Onboard 12V Air Compressor (CKMTA12)

Built for serious off-roaders and overlanders, the ARB CKMTA12 Twin Air Compressor delivers industry-leading airflow, 100% duty cycle performance, and the reliability needed for life beyond the pavement.

When you're miles from civilization and tire pressure can make the difference between moving forward or getting stuck, you need an air compressor you can trust. The ARB CKMTA12 Twin Onboard Air Compressor is ARB's flagship onboard air system, engineered to provide high-volume compressed air for rapid tire inflation, Air Locker activation, and a variety of compressed air applications.

Featuring dual high-performance motors and compressors, the CKMTA12 delivers exceptional airflow while maintaining a compact footprint that fits easily into modern overland and off-road builds. Its 100% duty cycle rating means it's built for continuous operation when the job demands it, whether you're airing up multiple vehicles after a trail run or managing air systems during extended adventures.

Designed specifically for harsh environments, the compressor incorporates moisture and dust-resistant sealing, hard-anodized cylinder bores, Teflon-impregnated carbon fiber piston seals, integrated cooling systems, and heavy-duty electronics protection. From remote backcountry travel to professional off-road builds, the CKMTA12 remains one of the most trusted onboard air systems available.
