Utilizing the RAM®’s 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* 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.
