The VR140 underhood air compressor is designed for the 2008 Ford 6.8L Triton V10 Gas F250-F550 Super Duty trucks. It boasts up to 150 cfm/175 psi of power and is driven by the truck's engine. The compressors use a small air/oil separator tank mounted on the truck's frame rail, with the rest of the components mounted under the hood.
