ARB Twin Motor Onboard 12V Air Compressor

ARB Twin Motor Onboard 12V Air Compressor

by ARB
$659.95

Install dependable compressed air for tire inflation and trail support with ARB's brushed twin 12V compressor. The onboard configuration is designed for demanding off-road use, giving you a practical air source after airing down and supporting compatible ARB Air Locker systems.

With up to 6.16 CFM of free-flow output and 4.68 CFM at 29 PSI, this model balances inflation speed, electrical demand and package size for its intended use. Sealed components, hard-anodized cylinder bores and low-friction piston seals are engineered for long service life in dusty, wet and high-vibration environments.

The onboard layout provides a permanent, ready-to-use air source; application-specific mounting brackets, air tanks, manifolds and hose accessories may be required depending on the installation. Use appropriately rated wiring, fusing, hose and fittings, and follow ARB's installation instructions.
