Utilizing the vehicles own engine for power, Vanair® underdeck rotary screw compressor systems provide you with the exceptional power your crew needs to get the job done where and when they need it -without hauling an expensive air compressor tow-behind. Using a single PTO opening, these systems provide up to 200 CFM (Pump Sold Separately) of impressive air power, AC power or hydraulics, or any combination of all three. At half the cost of a tow-behind, PTO underdeck systems mount seamlessly out of sight, under the vehicle, leaving the towing hitch free for other equipment and opens up the truck bed for additional storage space.
