Abstract

A filter for separating contaminants from a gas stream, including (a) a housing having a housing body and a housing head, the housing head having an inlet for the gas stream to be purified, an outlet and a first sealing surface, and (b) a filter element accommodated in the housing, having an element head and an element body having a central element axis and an element interior. The element head has a second sealing surface which cooperates with the first sealing surface. A curved inlet manifold is formed between the inlet and the element interior. The inlet manifold is embodied partly in the housing head and partly in the element head such that the first and second sealing surfaces contact in a sealing plane at a 90° to 60° angle to the element axis. A radially arranged seal is provided on the sealing plane, forming one of the sealing surfaces.
