Tough Jobs Need Serious Air Power!

When you need serious air power to get the job done quickly and efficiently, Vanair’s industry-leading PTO Underdeck Air Compressors provide you with up to 425 CFM and 150 PSI of air power. Seamlessly installed under the body on the frame rails, Vanair’s underdeck systems: are half the price of a tow-behind compressor, frees up the truck bed space for additional tools, leaves tow hitch free, allows for increased maneuverability on jobs, Tier 4F compliant, reduces ground vehicle weight (GVW), and reduces maintenance expenditures since there’s only one engine to service! PTO Driven Underdeck Systems are ideal for various applications such as: air excavation (clean, dry digging for potholing), shotcrete, daylighting, manhole relining, asphalt and paint striping, crack sealing and tacking, railroad grinding and track lifting, and various kinds of medium-duty blasting (soda, sand, CO2, etc).
