The ARB CKMTA12 is a 12V twin onboard air compressor engineered to meet the demands of off-road enthusiasts, overlanders, and adventurers. This compact yet powerful unit delivers high-volume compressed air, making it ideal for airing up tires after off-road excursions, engaging ARB Air Lockers, or operating air-powered tools in remote locations. Built for reliability and longevity, the CKMTA12 features a 100% duty cycle, allowing for continuous operation. Its construction includes hard anodized cylinder bores to reduce friction and Teflon-impregnated carbon fiber piston seals for extended trouble-free life. The compressor is sealed to resist moisture and dust ingress, ensuring performance in harsh environments. An anodized mounting bracket aids in heat dissipation, while an integrated pressure switch, relays, and an IP55-rated brushless fan keep the electronics and motor cool. Specifications for the ARB CKMTA12 include a maximum pressure of 150 PSI and an air flow rate of 174.3 liters per minute at 0 PSI (6.16 CFM). The unit operates on 12V and has a current draw of up to 50A under load. Its dimensions are approximately 10.8 inches in length, 7.5 inches in width, and 4 inches in height, with a weight of 17.4 lbs. This universal part may require some modification for proper installation. The ARB Twin Onboard Compressor is backed by a 3-year manufacturer's warranty.
