Dehumidifier

A dehumidifier for use in an air compressor system in which an air compressor supplies compressed air to a storage reservoir and a drain valve exhausts accumulated moisture to atmosphere, said dehumidifier comprising:

• (a) a housing having an inlet connected to the air compressor and an outlet connected to the storage reservoir;
• said housing further having formed at a lower portion thereof, a separating chamber, said separating chamber accumulates the moisture and other foreign matter until an exhaust operation occurs;
• (b) passage means formed in said housing via which compressed air may flow from said inlet to said outlet;
• (c) a tubular member interposed in and forming a part of said passage means with said housing, said tubular member having an inlet and a vane means interposed in said passage means upstream from said separating chamber for imparting a swirling motion to such air flow and directing such swirling air flow into said separating chamber thereby separating moisture and particulate material from such compressed air flow and passing the compressed air into the inlet of the tubular member;
• and
• (d) a body of desiccant material interposed in said tubular member and in said passage means for intercepting compressed air flowing therethrough and removing residual moisture therefrom.
