It will air a 33\" tire from 15 to 30 psi without drama, run air lockers, and hold 100 psi for tools and tire seating, with a 50% duty cycle that ARB rates honestly at 30 minutes on, 30 minutes off.\u003c\/p\u003e\n\u003cp\u003eUnlike a portable unit that rides loose in the back, the CKMA12 bolts to any flat surface through four 1\/4\" holes using the supplied backing plate as a drilling template, and the body rotates 180 degrees in its bracket to tuck into tight spaces. The kit ships genuinely complete: full wiring loom, 40 A relay, illuminated dash switch, pressure switch and mounting hardware are all in the box. Sealed to IP55 against dust and water, it has been designed and manufactured by ARB in Kilsyth, Australia since 2009, and carries ARB's 3-year warranty.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCKMA12 single-motor 12 V compressor assembly with over-pressure safety valve\u003c\/li\u003e\n\u003cli\u003eMounting bracket and backing plate (doubles as the drilling template)\u003c\/li\u003e\n\u003cli\u003eWashable sintered-disc air filter assembly\u003c\/li\u003e\n\u003cli\u003ePressure switch and manifold hardware\u003c\/li\u003e\n\u003cli\u003eComplete wiring loom with 40 A relay and illuminated ARB dash switch\u003c\/li\u003e\n\u003cli\u003eMounting bolts, washers and terminals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"embed-container\" style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;max-width:100%;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/NyIBwUuG8Io\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;\" frameborder=\"0\" allowfullscreen\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHigh-Output On-Board Air\u003c\/strong\u003e\u003cbr\u003e3.08 CFM of free-flow air and 2.34 CFM at 29 psi, enough to air up a 33\" tire from 15 to 30 psi in about two and a half minutes, run a locker, or seat a bead.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMounts Anywhere, Points Anywhere\u003c\/strong\u003e\u003cbr\u003eFour 1\/4\" mounting holes on the supplied backing-plate template, and the compressor body rotates 180 degrees in its bracket, so it fits engine bays, cargo drawers and under-tray spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEverything In The Box\u003c\/strong\u003e\u003cbr\u003eFull wiring loom, 40 A relay, illuminated dash switch, pressure switch and hardware are included, so the install needs no parts-counter trips.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSealed Against The Trail\u003c\/strong\u003e\u003cbr\u003eIP55-rated sealing keeps dust and water spray out of the motor, and the washable sintered filter is the only maintenance item.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHonest Duty Cycle\u003c\/strong\u003e\u003cbr\u003eARB rates the CKMA12 at a 50% duty cycle, 30 minutes on and 30 minutes off at 100 psi, instead of quoting a burst figure it cannot sustain.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBuilt By ARB In Australia\u003c\/strong\u003e\u003cbr\u003eDesigned and manufactured by ARB in Kilsyth, Victoria since 2009, and covered by ARB's 3-year North American warranty.\u003c\/p\u003e\n\u003ch3\u003eFitment \u0026amp;
