This "Constant Duty" Onboard Air System by Viair takes all of the guess-work out of getting all of the parts you'll need to install one of the most sophisticated, all-inclusive onboard air systems available today. The Constant Duty Onboard Air System comes complete with a long-running 450C, 100% Duty Cycle compressor at its heart that will fill the supplied 2.5 gallon tank from 110-150 PSI in approximately one minute. Unlike our other systems, the Constant Duty Onboard Air System can operate for longer periods of time without needing to rest. Included is everything you'll need to add a reliable air source to your vehicle as well as inflate tires with the included clip-on air chuck. (For vehicles with up to 37-inch tires)
