Product Details

ARB On-Board High-Performance Twin Air Compressors

The ARB on-board twin air compressors are compact, vehicle-mounted units designed to meet a variety of needs. From activating ARB Air Locker differentials to inflating a 35-inch tire in under a minute and powering air tools, these compressors offer unmatched versatility. With a 100% duty cycle (at room temperature), they are engineered for reliable performance in demanding conditions.

Key Features:

  • 12V
  • 3CFM @ 90psiĀ 
  • Compressor draw: 28-50amp
  • Durable Construction: Made from lightweight, high-strength engineering-grade materials, including military and aerospace-grade components.
  • Pressure Control: Integrated pressure switch-controlled air manifold system ensures regulated air pressure.
  • Efficiency: High airflow rate with an efficient design to minimize power consumption.
  • Sealed Components: Resistant to moisture and dust for durability in harsh environments.
  • Enhanced Longevity: Hard-anodized cylinder bores and PTFE-impregnated carbon fiber piston seals reduce friction and extend service life.
  • Effective Cooling: Features a ducted, sealed, brushless DC cooling fan and anodized motor mount brackets to dissipate heat.
  • Vibration & Noise Reduction: Anti-vibration, sound-deadening mounts for quieter operation.
  • Air Filtration: Relocatable, splash-resistant air filter assemblies with high-density, washable sintered bronze elements for cleaner air intake.
  • Simplified Installation: Includes a full wiring loom for easy installation and plug-in connectivity to Air Locker control solenoids (requires ARB-171503 manifold kit, sold separately).
  • Robust Motor Design: Equipped with ball bearings, a unique linear brush pre-load system, and cylindrical roller bearings for long life and efficient operation.
  • Safety Features: Over-pressure safety valve and dual heavy-duty Maxi-Fuses for circuit protection and redundancy.
  • User-Friendly Design: Comes with a sealed, illuminated automotive-grade dash switch.
  • Serviceability: Fully serviceable with available replacement parts.
  • EMF-Suppressed: Safe for use near sensitive electronic equipment.
  • Compliance: Meets CE and C-Tick standards.
  • Tested in Australia: Each unit is engineered, built, and individually dyno-tested to ensure quality.

Whether you need compressed air for tools, tire inflation, or operating ARB Air Lockers, the ARB onboard twin air compressor is a reliable and high-performance solution.
