ARB Single Motor Onboard 12V Air Compressor (CKMA12)

The ARB Single Motor Onboard 12V Air Compressor was designed and built for activating ARB Air Lockers and inflating tires.  More powerful and compact than the previous ARB RDCKA Air Compressor, the CKMA12 Air Compressor is also highly configurable to suit difficult mounting locations.  Once the compressor's ideal location is determined, the shape of the CKMA12 can be configured in several different ways to minimize the overall size of the unit and provide optimal access to the air ports.  All wiring, switches, and mounting hardware necessary for proper operation are included.

The top of the CKMA12 has three outputs and is nearly identical to the ARB Air Locker Manifold Kit, which is a small air tank with multiple ports that enables easy installation of two ARB Air Locker solenoids and a standard 1/4" NPT thread that accepts the ARB Air Compressor Pump Up Kit for inflating your tires.

The CKMA12 is a very capable unit and fits into tight spaces, but go with the bigger and more capable CKMTA12 Twin Motor Onboard 12V Air Compressor if you have the room or if you want to inflate large amounts of large tires.  The CKMTA12 is essentially two CKMA12 units combined together and fitted with a cooling fan for more air output and a 100% duty cycle. 

The CKMA12 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.

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 threads to 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 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.
