    Prep 40 compressed air dryers have been designed for the rugged demands of the rental equipment industry. Heavy duty structural steel frame work protects key components. The Prep 40 will produce compressed air with a -40°F pressure dew point, remove particulates down to 1 micron, and reduce lube oil content to .008 PPM.

    These dryer skids are as close to plug-n-play as equipment gets. Just hook up compressed air hoses, supply 115v power, and the dryer is ready to begin working. For the ultimate in mobility and portability, look no further than the Van Air Prep 40 regenerative compressed air dryer system.

    The Prep 40 series delivers clean, dry and cool compressed air in one integrated forklift skid package. The compressed air dryer package includes an aftercooler, moisture separator, pre- and after-filters, and an HL series heatless dryer. No other air dryer manufacturer offers a skid packaged regenerative compressed air dryer with an onboard aftercooler. The compete air drying package is designed for anyone who needs -40°F dry compressed air. Eliminate the use of a separate aftercooler and save time and hassle with portable air preparation packages for cool, clean and dry compressed air.
