ARB Onboard Air Compressor



ARB Onboard Air Compressor
The ARB CKMA12 delivers reliable onboard compressed air for off-road and overlanding demands. Designed as a compact, vehicle-mounted solution, this single-motor 12V compressor provides consistent performance for tire inflation, activating ARB Air Lockers, and light air tool use when paired with an optional tank. Built to handle real-world abuse, it features sealing against moisture and dust ingress, along with quality engineering for quiet, long-term operation.
The unit mounts flexibly in engine bays, behind seats, or other protected locations, with an anodized bracket that dissipates heat and allows 180-degree repositioning for optimal fitment. Hard-anodized cylinder bore reduces friction, while the Teflon-impregnated carbon fiber piston seal promotes durability and trouble-free service life. Internal thermal protection guards the motor from extreme temperatures, and a heavy-duty maxi-fuse ensures circuit safety.
With a 50% duty cycle (30 minutes on/30 minutes off), it balances capability and longevity for extended trips. Rated to 100 PSI maximum and drawing up to 32 amps under load, it flows 3.08 CFM at 0 PSI and 2.34 CFM at 29 PSI—sufficient for airing up 33-35 inch tires efficiently or maintaining air pressure during remote travel. This compressor integrates seamlessly into 4x4 and overland setups where dependable air supply matters most.
