Air down for the track, then get your tyres ready for the road with a compressor you can carry between vehicles. The ARB CKMTP12 twin compressor brings the motors, 4-litre air tank, battery connections and inflation equipment together in a robust carry case for your 12 V electrical system.
SKU: XAACCKMTP12
Twin brushed motors deliver 174.4 L/min of free air at 0 kPa, with 131.8 L/min at 200 kPa. The loaded figure gives a more useful comparison for tyre inflation than free-air output alone. The compressor has a 100% duty-cycle rating at 22 degrees C, supported by cooling and thermal protection.
The case keeps the compressor and accessories together, with battery clamps for direct connection to a suitable supply. Set it on firm ground, open the lid for cooling and use the included hose and tyre-filling equipment. The 15 kg kit is designed to carry, without requiring a permanent compressor mount.
Choose this twin kit when you want a portable 12 V air supply with a 4-litre tank and 131.8 L/min of airflow at 200 kPa. The complete kit weighs 15 kg. If lower carrying weight matters more, the CKBLP12 brushless portable single weighs 7.9 kg and delivers 88 L/min at the same pressure, with a 90% duty-cycle rating at 22 degrees C. This twin has the higher loaded airflow of those two portable kits; the single is lighter to move and adds brushless control and diagnostics.
The 4-litre tank buffers the air supply and the pressure switch controls cycling between approximately 135 and 150 psi. It is useful for inflation and compatible air accessories. Air tools must be matched to the compressor's pressure and flow capability; tank capacity alone does not make every tool suitable.
Use the correct 12 V battery supply and keep the clamps, hose and filters clean. Follow the manual for draining accumulated moisture from the tank, and inspect the equipment after dusty or wet trips. A digital tyre inflator is a useful addition when you want clear pressure readings and more precise filling control.

Yes. CKMTP12 is the 12 V version. Connect it to a suitable 12 V battery supply using the supplied clamp arrangement and follow the manual.
No. It is a portable kit in a carry case. You can take it between suitable vehicles, with the correct voltage supply, and pack it away after use.
The 4-litre tank provides stored air for short bursts and helps the system cycle with demand. For sustained use, match the accessory's consumption to the compressor output at its operating pressure.
Yes. This twin-compressor kit is built for airing up your vehicle after an off-road trip. Work around the tyres with the included inflation equipment, keeping the carry case open for cooling. Its loaded airflow is 131.8 L/min at 200 kPa, with a 100% duty-cycle rating at 22 degrees C. Filling time varies with tyre size, starting pressure and valve restriction.
It can supply compatible tools whose pressure and air consumption are within the operating guide's limits. Check the tool's sustained demand; a tool that uses more air than the compressor produces will empty the tank.
Keep the filters and connectors clean, check the hose and wiring, and drain tank moisture as directed by the manual. Store the dry kit with the accessories secured in their case compartments.
