ARB Air Compressor Single Motor Onboard 12V

ARB Air Compressor Single Motor Onboard 12V

The ARB Air Compressor Single Motor Onboard 12V is a compact brushed compressor for drivers who want permanent air for one 4x4 and nothing more complicated. It weighs 3.5 kg (7.7 lb), bolts in once and stays wired. The air is there every time you head home from the sand.

Features and Benefits

The single motor delivers 87 L/min (3.1 CFM) of free flow. At 29 psi (200 kPa) it moves 66 L/min (2.3 CFM). Maximum pressure is 100 psi (690 kPa), comfortably above typical off-road tyre pressures. ARB rates the duty cycle at 50%, or 30 minutes on and 30 off. Maximum current draw is 32 A.

Additionally, the compressor is sealed for moisture and dust resistance. A hard-anodised cylinder bore reduces friction. ARB fits a Teflon-impregnated carbon fibre piston seal, which it says gives a long, trouble-free life. The anodised mounting bracket draws heat away from the motor. It also lets you reposition the compressor 180 degrees on the vehicle.

Moreover, protection is built in. You get an over-pressure safety valve and internal thermal protection on the motor. A heavy duty maxi-fuse provides in-line circuit protection. ARB leak tests, current draw tests and flow tests each compressor under load before packing.

Product-Specific Use Cases

After a dune session at Sweihan, this unit gets one vehicle back to road pressure. The 50% duty cycle suits airing up your own tyres with rest breaks. ARB Air Compressor Single Motor Onboard 12V is not meant to run non-stop for a whole convoy. It also re-inflates a tyre after a puncture repair on a rocky track.
