The Cool Pak is an aftercooler/filter combo for portable air compressors that delivers cool filtered compressed air for portable jobs. Each Cool Pak consists of an air-cooled after-cooler with a 12VDC motor, 25 micron air filter/bulk moisture separator with a manual drain. All of this is conveniently packaged on a steel constructed stand, with a rock guard, and protective cord wrap for ease of portability. The Cool Pak reduces the harmful effects of liquid contaminants. The Cool Pak is designed for use with portable 185 CFM compressors whenever a Dry Pak PRO air dryer is not an economic solution.
