Excellent for eliminating moisture and dirt from an air supply, DeVilbiss CleanAir centrifugal units supply cleaner, drier air to each spray gun. Cleaner air can increase the life of pneumatic tools. Filters out water and oil aerosols and dirt particulates to 5 microns. Water droplets collected in the bowl are removed by an automatic drain (standard feature), so there is no need to manually drain the system. Filter also includes a quick-release bowl and spin-off element for filter changes without tools.
