Abstract

A filter element for separating a liquid from a gas stream, e.g. for de-oiling compressed air produced by an oil lubricated compressor, including an annularly closed filter medium and upper and lower end disks at the axial end faces of the annular filter medium, in which the lower end disk closes off an interior space formed by the filter medium, and a drainage tube extends into the interior space and is guided at the upper end disk by a preferably conical sealing element mounted on a support plate on the upper end disk such that when the filter element is installed in a container, the sealing element fits against and forms a seal with a cover of the container. The sealing element optionally has a hollow interior to facilitate compensation of tolerances in at least one of the x-direction and the y-direction.
