Air Compressor Kit - a twin-motor 12-volt on-board air compressor for permanent vehicle mounting, supplying compressed air to engage ARB Air Lockers, inflate tyres, and run air tools. The pressure switch controlled manifold regulates output between 9.3 and 10.3 bar (135 to 150 PSI). Each motor incorporates internal thermal protection and a heavy-duty in-line maxi fuse. This kit includes the assembled and tested 12-volt compressor, a complete wiring loom with Air Locker solenoid plug-in terminals, a compressor isolating switch, two relocatable splash-resistant air filters with washable sintered-bronze cartridges, mounting bolts and washers, and an illustrated installation guide. An air hose and tyre inflation gauge are not included. The ARB Air Locker Manifold Kit is required to control ARB Air Lockers.
