ARB INFLATION3 Twin High Performance Air Compressor - Fast Inflation

In this review the ARB INFLATION3 Twin compressor is judged on durability, flow and install convenience for 4x4 owners and workshop use. The bottom line: it is aimed at drivers who need a compact, high-flow 12V unit that moves air quickly and connects cleanly to lockers, horns and air tools. The standout reason to buy is its twin motor, dual cylinder design that delivers the highest airflow in its size class, making it noticeably faster at inflating large truck and off-road tires while the included wiring loom simplifies hookup to control solenoids.

Key Features

• Water sealed, ball bearing motors: Motors are fully water sealed and use 100% ball bearings for long life, low heat and consistently quiet operation.
• High airflow twin motor design: The compact twin motor, dual cylinder layout produces up to 174 LPM (6.16 CFM), so tires and tools fill faster than many single motor compressors of similar size.
• Full wiring loom included: A complete wiring harness is supplied to simplify installation and provide plug-in connectivity to air locker control solenoids.
• Thermal protection and safety: Motors include internal thermal protection and an over-pressure safety valve to protect the unit under heavy use.
• Heavy duty internals: Pistons use European cylindrical roller bearings with hard-anodized bores and PTFE-impregnated carbon fibre seals to reduce friction and extend service life.

Who It's For

The ARB INFLATION3 is best for off-roaders, 4x4 owners and small workshops that need a reliable, high-flow 12V compressor for inflating large tires quickly and operating air lockers or pneumatic accessories. Its fast inflation rate and full wiring loom make it a practical choice for installations where space is limited but performance matters.

Those who should look elsewhere include buyers who need a basic, low-cost inflator for occasional passenger car use or someone seeking a permanently mounted industrial compressor with water-cooled or heavier duty continuous-duty ratings beyond typical automotive applications.

Pros & Cons
