Dry-Pro™ Aftercoolers are a skid mounted system which includes an aftercooler, coalescing filter and moisture separator. Warm air enters the aftercooler where it is cooled close to the surrounding temperature, water is then condensed out during this cooling process. The saturated air and the liquid water pass through a moisture separator where it is trapped and drained. The air then passes through a coalescing filter where any oil contaminants from the compressor are removed.
