Hard Unit 12V Air Compressor 72LPM PortableAiring down for the sand and back up for the bitumen is part of any 4WD trip. A decent compressor makes it quick instead of a chore. This Hard Unit unit pushes 72 litres a minute and runs straight off the battery with a 3 metre clip lead. The 6 metre hose reaches all four tyres without moving the car, and the dual scale gauge reads PSI and kPa so you hit the right pressure. It packs down into its own carry bag with all the connectors and fittings.
