VIAIR’s Medium Duty Onboard Air System is a pre-packaged compressed air solution that provides a 33% duty cycle 325C compressor, 2.5 gallon air tank, and all components needed to install basic vehicle-based pneumatics.
Please Note: Pressure Switch w/Relay (PNs 90110, 90111, 90113, 90118) is not a sealed unit and should be installed in an area protected from the elements to prevent damage and/or failure.
Use thread sealant for proper installation. Thread tape is not recommended. Properly sealed, recommended torque for 1/8″ is 10 ~ 11 ft. lbs. Recommended torque for 1/4″ and 3/8″ is 12 ~ 15 ft. lbs.

Overview
Medium Duty provides a vehicle-mounted compressed-air supply for owners who need both stored air and controlled operation from the cab. It combines the 325C compressor, a 2.5-gallon reservoir and a dashboard gauge with switch. The 33% duty rating at 100 PSI gives a useful benchmark for intermittent inflation and pneumatic work. Its compressor has IP67 protection, but VIAIR specifies that the separate pressure-switch/relay assembly must be mounted somewhere protected from the elements.
