An in-line vapor trap for removing water and/or oil vapor from a compressed air line which includes a manifold having spaced coaxial inlet and outlet openings, a hollow base suspended from the manifold, and replaceable cartridges connecting the manifold inlet to the hollow base and connecting the hollow base to the manifold outlet. A honeycomb structure is disposed in the lower portion of the base within the enclosed volume defined thereby, and cooperates with the base side and bottom walls to define a zone of substantially zero air movement for collection of liquid droplets. A depression in the base bottom wall forms a liquid sump, and a drain opens into the sump for drainage of captured liquid. This drain features an enclosed bowl suspended by a hollow fitting beneath the sump, and an aspiration tube which extends from within the bowl through the fitting and sump to adjacent the exit from the hollow base, such that air is circulated from within the base through the fitting into the bowl and then aspirated therefrom through the tube. Liquid collected in the sump is drawn by such air circulation into the bowl.
