ABSTRACT:
An air filter dryer for adsorbing moisture from an air flow of the type typically found in a pneumatic power system comprises a housing having an inlet fitting and an outlet fitting arranged such that the filter dryer can be installed directly in line with system piping. The filter dryer also includes a series of filters arranged symmetrically at each end of the housing. Included in the series of filters are dispersion filters which collect moisture in the air flow and also disperse the air evenly across the housing. An oil removal filter is located adjacent each dispersion filter in the filter arrangement, and acts to remove any oil contaminants from the air flow. This filter dryer further includes a silica gel desiccant, located between the respective oil removal filters, which adsorbs moisture from the air stream. The air then passes through the second symmetrically arranged series of filters, and exits through the outlet fitting.
