Abstract: The present invention relates to a steam trap for draining off condensate from a collecting chamber in which condensate resulting in a pressure gas system is collected, the collecting chamber being pressurized by a gas pressure which, depending upon the operating state of the pressure gas system, may be a negative pressure below the atmospheric pressure, an overpressure above the atmospheric pressure or an atmospheric pressure itself. The steam trap may be separated via an interface into an integral first assembly unit and an integral maintenance assembly unit which comprises the essential wear and tear parts.

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.

Abstract: The invention relates to a filter for the separation of contaminants from a gas stream, comprising a) a multi-piece housing with a housing body (20) and a housing head (22), whereby the housing head (22) has an inlet (26) for the gas stream to be purified and an outlet (30) and the housing head (22) furthermore has a first sealing surface (32) and b) a filter element accommodated in the housing, with an element head (36) and a tubular element body (38) which has a central element axis (42) and an element interior (44), whereby the element head (36) has a second sealing surface (48), which co-operates in a detachable manner with the first sealing surface (32) and a curved inlet manifold (50) is formed between the inlet (26) and the element interior (44).
