Abstract
A filter arrangement for a moisture-removal device used in compressed air systems in which an inner filter adapted to remove water from the air is encircled by an outer filter that is adapted to remove oil from the air. A space between the inner and outer filters is provided to accommodate accumulation of the filtered-out oil with a valving arrangement provided in the area of oil accumulation that is operative in response to a pressure differential when the regeneration phase of operation is initiated to concurrently discharge the accumulated oil.
