ARB Twin Motor Onboard 12V Air Compressor (CKMTA12)

The ARB Twin Motor Onboard 12V Air Compressor fills the need for an air compressor of compact size, yet with high-volume output and 100% duty cycle.  Because of its unique mix of high performance, reliability, and full tech support and parts support from ARB USA, this Twin Motor Air Compressor became the Gold Standard in vehicle-mounted onboard air and even obsoleted the engine-driven air compressors and CO2 air tanks that were popular among fourwheelers more than a decade ago.  This air compressor is so good that it changed the 4x4 landscape.

The output is suitable for inflating tires, powering ARB Air Lockers, and for running air tools.  A ducted cooling fan dissipates heat and gives the Twin Air Compressor a 100% duty cycle.  Even if one compressor overheats and shuts down from activation of the thermal relay, the other compressor will continue to run.  The pressure switch turns on the compressor at 135 psi and shuts off the compressor at 150 psi.  The sintered bronze air filters are splash-resistant and washable.  All wiring, switches, and mounting hardware necessary for proper operation are included.

The CKMTA12 Twin Motor Air Compressor is part of ARB 4x4's line of proven air compressors that includes:

• ARB Brushless Single Motor Onboard 12V Air Compressor (CKBLA12)
• ARB Brushless Twin Motor OnBoard 12V Air Compressor (CKBLTA12)
• ARB Single Motor Onboard 12V Air Compressor (CKMA12)
• ARB Twin Motor Onboard 12V Air Compressor (CKMTA12)

The ARB air compressors with brushed motors are far from obsolete.  They are excellent units that have been proven after many years of hard use all around the world.  While the new brushless air compressors offer 50% more air output, keep in mind that the brushless units also cost about 50% more.

The twin-motor units are the way to go and the single-motor units come into play only if you absolutely cannot fit a twin-motor unit into your vehicle's dead space.

Probably the simplest and easiest onboard air system for your vehicle is to pair your ARB air compressor with the ARB Air Compressor Pump Up Kit.  The output end of the air compressor has standard 1/4" NPT threads that accept the Pump Up Kit's quick-connect air coupler, which accepts the air hose, which accepts the inflation fitting, which connects to your tire valves.  Everything is plug and play and very simple and intuitive.

If you want to use your ARB Air Compressor as an air source for both ARB Air Lockers and inflating tires, take a look at the ARB Air Locker Manifold Kit.  The Air Locker Manifold Kit is a small air tank with multiple output ports that enables easy installation of two ARB Air Locker solenoids and the ARB Air Compressor Pump Up Kit to your vehicle's onboard air system.

If you desire even greater performance, you can pair your ARB Air Compressor with the ARB 4-Liter Aluminum Air Tank to have about a gallon of compressed air always at the ready for tasks such as seating tire beads or heavy air flushing with a blowgun.

Approximately 90% of your trail fixes will involve tires.  And nearly all fourwheeling involves deflating and inflating tires.  So having an onboard air system on your 4x4 is mandatory.  Acquire the tools and skills to perform tire repairs and you will be well on the way to becoming a compleat offroader.
