Tech Insight

The ARB Twin Motor Compressor is one of the highest-output 12V onboard compressors ever built. With two motors and two cylinders pushing over 6 CFM at zero PSI, it supports high-demand applications such as:

  • Repeated tire inflation for large off-road tires
  • Air tools when paired with a reservoir
  • Continuous Air Locker engagement
  • High-heat environments where lesser compressors fail

ARB’s use of hard anodized cylinder bores, Teflon-impregnated carbon fiber piston seals, and a sealed electronics package drastically increases service life. The result is a powerhouse compressor trusted worldwide by adventurers.
