AirPrep a high efficiency system to remove moisture from your compressed air. The ACS Aftercooler system uses an Aftercooler fan to cool the compressed air - the cool air then flows into a large coalescing tank where the cool air/moisture spins through stainless steel coalescing elements that drops the moisture out of the system. Pneumatic fan motor includes filter regulator lubricator and muffler. Electric fan motor also available. There is negligible pressure loss through the AirPrep system thanks to the oversized Radiator/Heat Exchanger.


The workhorse of the industry.  This air dryer will manage anything you put through it.  Often used on a skid with a blast pot mounted beside it.
