CKMTA12 – ARB On-Board High Performance 12V Twin Air Compressor

Big Air. Compact Package. Built for the Trail.

If you’re running ARB Air Lockers, oversized tires, or just want to air up without relying on a gas station (or weak portable compressor), the CKMTA12 is your solution. This is ARB’s top-tier twin 12-volt on-board compressor, originally designed under military contract and built to handle the toughest environments out there.

It’s compact, powerful, and engineered to deliver the highest airflow rate of any 12V compressor in its class—174 LPM (6.16 CFM). Whether you're running air tools, inflating tires, or powering lockers, this compressor gets the job done without breaking a sweat.

Key Features:

  • Dual high-output 12V motors with the highest flow rate in its class

  • 174 LPM (6.16 CFM) free-flow at 0 PSI

  • 85 LPM (3 CFM) at 6 Bar (90 PSI) for continuous use with air tools

  • Pressure-regulated manifold maintains 135–150 PSI range

  • 100% duty cycle under room temp conditions

  • Constructed from military-grade and aerospace-standard components

  • Moisture and dust sealed components with anodized brackets and IP55 brushless fan

  • Includes full wiring loom, filters, isolator switch, and hardware

  • Compatible with ARB Air Lockers (manifold kit #171503 required for solenoids)
