VIAIR 10003 horizontal 2.5 gal air tank with 12V compressor, 30 lb

VIAIR

VIAIR 10003 Medium Duty Onboard Air System 12V 150 PSI air compressor

SKU CH-CQ75-W6TCY

Portable 12 V air compressor delivers .82 cfm free-flow at 150 psi maximum pressure from a 2.5 gal horizontal tank

  • Oil-free operation reduces maintenance needs
  • 82 cfm free-air flow delivers steady inflation
  • 150 psi maximum pressure handles demanding tasks
  • 5-gallon tank stores ample compressed air
  • 73 dB sound level keeps noise moderate

Portable Onboard Air System

The VIAIR 10003 is a 12V DC compressor kit designed for vehicle-mounted inflation tasks. It suits off-road drivers, overland travellers and utility fleets that need a self-contained air source without relying on shop air or portable cans. The system arrives new and ready for permanent installation on a chassis or in a cargo area.

Oil-Free Horizontal Tank Build

A 2.5 gal horizontal tank sits on a 30 lb frame that bolts directly to the vehicle structure. The oil-free reciprocating pump eliminates routine lubrication and reduces the risk of oil vapour in the air line. A permanent-magnet motor draws 22.0 A from the 12V electrical system, so wiring and fusing must support that continuous load during each duty cycle.

150 PSI Maximum Pressure

The compressor delivers 0.82 cfm free flow and 0.57 cfm at the rated 150 psi ceiling, driven by a 0.35 hp single-stage pump. Output drops as pressure climbs, so the unit inflates typical light-truck tyres but will not sustain high-volume tools such as impact wrenches or sand blasters. Noise measures 73 dB during operation.

Questions about this item

What voltage does the VIAIR 10003 system require, and what current draw should I plan for?

The unit runs on 12 V DC and draws 22.0 A during operation, so wiring and fuse must support that load.

What are the tank capacity and overall weight for mounting clearance?

The horizontal tank holds 2.5 gal and the complete system weighs 30 lb, requiring a secure, level mounting surface.

How is the compressor installed, and what step is commonly missed?

Mount the tank horizontally, connect 12 V power with a 22 A-rated fuse, and plumb the pressure switch — many forget the fuse and relay, causing voltage drop.
