Portable Twin High Performance 12 Volt Air Compressor (CKMTP12)


ARB’s new CKMTP12 twin portable air compressor was designed to fill the market need for a compact sized yet high performance compressed air source for rapid inflation of large tires as well as the high volume air needs of most air powered tools. The CKMTP12 is a world class recreational product designed and built to commercial/industrial standards to survive harsh and demanding outback conditions.

Ultra compact twin motor, dual cylinder design makes this the highest flowing portable compressor of its size on the market at 174LPM [6.16CFM].

Integrated aluminium air tank and pressure switch regulates pressure between 930kPa [135PSI] and 1030kPa [150PSI] which is suited to most air powered tools.

Mounted in a waterproof carry case constructed from a durable impact resistant polymer. The carry case has convenient compartments for storing the air hose and other compressor accessories.

Ducted IP55 sealed brushed DC cooling fan and anodized aluminium motor mounting brackets effectively dissipate heat from the motors, heads and electronics allowing for a 100% duty cycle (under room temperature conditions).

  • Anti-vibration / sound deadening is integrated into the mount
  • Engineered, built and individually dyno-tested in Australia from local and imported components
  • Fully serviceable with all replacement parts available
  • Constructed primarily of light weight, high strength engineering grade materials, including military and aerospace standard components
  • Hard-anodized cylinder bores and PTFE (Teflon) impregnated carbon fiber piston seals for reduced friction and maximum trouble free life
  • Built with sealed components for moisture and dust resistance
  • Motors are water sealed, 100% ball bearing equipped (i.e., no bushings used), and feature a unique linear brush pre-load system for extra long life, low heat and quiet operation throughout the life of the unit
  • Compressor pistons are equipped with high shock rated roller bearing
  • High density and high flow washable sintered bronze air filter element
  • Motors are thermal cut-out protected against damage caused by extreme temperature use
  • Pressure switch and relay equipped electrical system prevents run-on when not filling, or any damage to compressor or hoses as a result of the pressure generated from a kinked air line
  • Illuminated isolating switch is easy to see at night, and protects the user from hazardous sparking when connecting the alligator clips to the battery terminals
  • Equipped with dual heavy duty Maxi-Fuses for professional in-line circuit protection and true circuit redundancy in case of a fault
  • Over-pressure safety valve equipped as a back-up protection from either pressure switch failure, thermal over pressure generated in a hot vehicle (i.e., no need to drain pressure when finished use.), or accidental connection to an external high pressure source
  • CE and C-Tick compliant


Few 4x4 accessories offer as many advantages to off-roaders as readily available on-board air. Considered by 4x4 owners around the world to be a staple accessory for off road travel, an ARB 4x4 Air Compressor provides an immediate source of compressed air anywhere a 12 or 24 volt power source is available.

Tires perform best when they're set at a pressure that's appropriate for the terrain. While highway use calls for a relatively high pressure rate, lowering your air pressure will dramatically improve your 4x4's traction in a range of off road environments. Compressed air allows you the freedom to adjust the tire inflation level of your truck to suit the conditions.

An equally beneficial feature of on-board air is the ability to re-inflate tires that have been repaired - it's not unusual to get several punctures in one day when traveling in extreme off-road conditions. In this environment, the value of owning an air compressor is priceless. When coupled with good quality tire repair equipment, an ARB air compressor provides the off road traveler with independence and peace of mind.

ARB 4x4 Air Compressors are individually leak tested, current draw tested and flow tested under load at the factory before packaging and come with a comprehensive 2 year warranty. And ARB's after-sales service is second to none with many of the compressor components readily available and easily sourced.

Along with ARB Air Compressors, ARB also offers a range of tire accessories including tire deflators, tire inflators and tire repair kit. A perfect pairing with ARB Air Compressors.

Carry Case

After looking at the many cases available on the market, ARB Engineers decided that none met their exact requirements for the ARB Twin Portable compressor. The case needed to be compact, yet hold all accessories and air tank whilst also being extremely strong to handle the rigors of 4WDing and commercial use. Considerable time was therefore spent designing and testing a case that has features unique to ARB.

  • Enlarged carry handle to suit a gloved hand
  • Enlarged latches to suit a gloved hand
  • Aluminium latches ensure that no compression set in the latches occurs over time so they were able to reduce the clamping force (make them easier to unlatch) versus their competitors who all use plastic latches that will loosen up over time, and have subsequently needed to make their latches extra-extra uncomfortably tight when new to compensate
  • One piece heavy duty hinge
  • Shatterproof polymer compound (airport tested!)
  • 2 sides are textured, logo’d, generally attractive – not just the top as with most other cases
  • Air travel equaliser valve to combat cabin pressure crush when landing
  • Water tight seal in lid
  • Volume of case will assure the portable CKMTP12 floats if dropped in water
  • Quick-change (removable) accessory pocket mounts
  • Slotted internal design to suit organisers/dividers (not included)


  • Fully assembled and performance tested air compressor and air tank mounted into a water proof carry case
  • Canvas compartment for storing air hose and compressor accessories
  • OEM quality illuminated compressor isolating switch
  • High quality wiring loom with automotive grade alligator clamp type battery contacts, and a pressure switch driven automotive relay control circuit
  • Two splash resistant air filters with washable high-flow sintered bronze filter cartridges
  • 6 meter [20 ft] long high quality abrasion and heat resistant air hose with male to female couplings
  • Hose couplings are specially designed corrosion resistant, one-handed (push-lock) quick connect type to suit
  • US industrial standard air fittings
  • Air blow gun with US industrial standard male air fitting
  • Inflation accessories kit including high-flow tyre filler attachment (US industrial standard) with integral stop-valve, a Schrader valve to US industrial standard adaptor, and extra nozzle attachments for inflating items such as sports balls, air mattresses, etc
  • Comprehensive photo illustrated operating instructions


  • Rapid inflation of small, medium and large tyres
  • Air tools rated up to 174LPM (6.16CFM) continuous supply - check your air tool’s specifications to ensure that its air requirements are within the above limits
