Abstract
An air dryer (2) for an air brake system of a truck or the like includes separate heat exchanger and filtering housing sections (16 and 18) mounted side-by-side in a compact integral housing unit (10). The heat exchanger cools the air to condense water therefrom, and a water repellant downstream filter (42) permits air flow therethrough but blocks the passage of water. A pressure responsive valve (82) communicates with the outlet of the heat exchanger and the inlet of the filter for discharging water condensed from the heat exchanger and repelled by the filter.
