ARB On-Board 12V Twin Air Compressor — On-Board Air for Lockers & Tires | CKMTA12

The ARB CKMTA12 Twin Motor On-Board Air Compressor is ARB's flagship 12V on-board air solution — engineered for serious off-road use. Twin motors deliver maximum airflow for rapid tire inflation, simultaneous front and rear Air Locker engagement, and air tool operation, all at a continuous 100% duty cycle.

Key Features

• Twin-motor design for maximum airflow and continuous-duty performance
• 100% duty cycle — runs indefinitely without cool-down
• Engages ARB Air Lockers on demand for instant traction
• Inflates tires rapidly and powers air tools (compatible with optional 4L air tank)
• Hard anodized cylinder bores for reduced friction and extended service life
• Teflon-impregnated carbon fiber piston seals for maximum trouble-free life
• Integrated pressure switch, relays, and IP55-rated brushless cooling fan
• Anodized mounting bracket dissipates heat during operation
• Over-pressure safety valve equipped
• Sealed for moisture and dust resistance — suitable for under-bonnet or in-cab mounting

Compressor Connect App

The CKMTA12 is compatible with the ARB Compressor Connect app and ARB Pressure Control accessory. Inflate or deflate your tires remotely, set target tire pressures, and control your compressor directly from your mobile device — no need to keep a separate inflator, deflator, or pressure gauge on hand.
