🧾 Overview
The ARB 12V Twin On-Board Air Compressor is a compact, high-output air system engineered to meet the demanding airflow requirements of off-road vehicles equipped with air lockers and air-powered accessories. Designed to operate reliably in harsh environments, this compressor delivers exceptional performance for tire inflation and ARB Air Locker activation, while remaining compact enough for permanent on-board mounting.
Featuring a 100% duty cycle and sealed construction for moisture and dust resistance, the ARB Twin Compressor is built for continuous operation in extreme conditions. Hard-anodized cylinder bores reduce friction and heat, while Teflon-impregnated carbon fiber piston seals ensure long service life and trouble-free operation.
An anodized mounting bracket dissipates heat efficiently, and integrated relays, pressure switch, and an IP55-rated brushless cooling fan actively manage heat across the electronics, motors, and cylinder heads. When paired with an optional 4-liter air tank, this compressor is capable of supporting many air tools in addition to rapid tire inflation.
✔ High-output twin motor design
✔ 100% duty cycle for continuous operation
✔ Sealed for moisture and dust resistance
✔ Designed for tires and ARB Air Locker activation
