The CKMTA12 is ARB's twin-motor onboard compressor, mounted permanently in the engine bay and wired to the battery. Two motors deliver 6.16 CFM combined at a 150 PSI cap, fast enough to power air lockers and run pneumatic tools in addition to inflating tires. Typical installs pair the head with a small reserve tank. The highest-output option in ARB's onboard line.
