ARB On-Board High Performance 12 Volt Air Compressor (CKMA12)

SKU 22178 Categories ,


This compressor is permanently fixed in your vehicle and comes complete with a full wiring loom, air locker solenoid plug-in contacts, mounting hardware, a strengthening bracket, and a high-quality compressor isolating switch. With the installation of the ARB Pump-Up Kit (part #171302), this compressor can activate air lockers and do other tasks like inflating camping goods.

So, what distinguishes this compressor? It’s compact enough to fit into even the tiniest of spaces and quiet enough to use in the cab. It has adequate power to blow up four 35″ – 37″ tyres in a single duty cycle and takes a little over two minutes to air up 35″ tires. It also works. This device has performed admirably in ovens, freezers, underwater, and in the silty dust of the Simpson Desert.
