ARB CKMTA12 On-Board Brushed Twin Air Compressor 12V – High-Output 4x4 Recovery Air System

ARB CKMTA12 Brushed Twin Air Compressor – Premium On-Board Air Solution

The ARB CKMTA12 On-Board Brushed Twin Air Compressor 12V is engineered for demanding off-road, expedition, and 4x4 builds requiring rapid tyre inflation, reliable operation of ARB Air Lockers, and support for pneumatic tools. Designed by ARB, a leader in off-road recovery equipment, this compressor delivers class-leading airflow and durability in a compact, permanently mounted package.

How the ARB Twin Compressor Supports Your Vehicle

This compressor provides a powerful, high-volume air source directly from your vehicle, allowing you to:

• Inflate small, medium, and large off-road tyres rapidly after deflation for traction or sand driving
• Operate ARB Air Locker differentials for improved off-road capability
• Power air tools (when paired with an air tank) for field repairs or workshop tasks

Its twin motor design ensures consistent, high-output airflow, making it suitable for vehicles running larger tyres, beadlocks, or those frequently venturing into remote or rugged environments.

Where the ARB CKMTA12 Excels

The ARB CKMTA12 is ideal for:

• Overland and expedition vehicles needing reliable onboard air
• Off-road builds with 35–40 inch tyres
• Vehicles equipped with ARB Air Lockers
• 4x4 touring setups requiring fast, repeatable tyre inflation
• Mobile workshop applications demanding consistent pneumatic power

Whether you’re tackling remote tracks, rocky trails, or desert crossings, this compressor is widely used in serious off-road builds worldwide for its reliability and performance.

Key Benefits of the ARB Brushed Twin Compressor

• Extremely fast tyre inflation for all off-road tyre sizes
• Direct integration with ARB Air Locker systems
• Supports air tools up to 85 L/min (3 CFM) at 90 PSI
• Compact, vehicle-mounted design saves space and time
• Fully sealed motors and IP55 cooling fan for durability in harsh conditions
• Hard-anodised cylinder bores and PTFE-impregnated piston seals for long service life
• Anti-vibration mounting and sound dampening for quiet operation

Construction and Durability Features

Built for the rigours of off-road use, the ARB CKMTA12 features:

• Hard-anodised cylinder bores to minimise wear
• PTFE-impregnated carbon fibre piston seals for extended lifespan
• Fully sealed twin brushed motors for dust and moisture resistance
• IP55 sealed cooling fan for continuous operation
• Over-pressure safety valve for system protection
• Ball bearing motor construction for reduced heat and improved efficiency

These engineering details ensure the compressor withstands continuous use in extreme environments, making it a trusted choice for off-road professionals and enthusiasts alike.

Installation and Usage Considerations

The ARB CKMTA12 is designed for permanent installation in 12V vehicles. Common mounting locations include the engine bay, under-seat brackets, drawer systems, or dedicated compressor mounts. The kit includes a comprehensive wiring loom, dashboard switch, relocatable splash-resistant air filters, and all necessary mounting hardware. Vehicle-specific mounting kits are available for many popular 4x4 platforms.

The relocatable air filters allow intake air to be drawn from cleaner areas, extending compressor service life. The system is pressure switch regulated between 135–150 PSI and draws a maximum of 56A, so ensure your electrical system is capable of supporting this load.

Technical Specifications

Solving Real-World Off-Road Challenges

Off-road and expedition vehicles face the constant challenge of tyre pressure management and the need for reliable pneumatic systems in remote areas. The ARB CKMTA12 solves this by providing rapid, repeatable air delivery for tyres and lockers, reducing downtime and increasing confidence when venturing far from support. Its robust design ensures it keeps working in dust, mud, and water, supporting your vehicle’s capability in the harshest conditions.

Frequently Asked Questions

What vehicles can the ARB CKMTA12 be installed in?
