A fluid housing of a fluid treatment system of a fluid system has a housing part of plastic material that is provided with a receiving chamber for accommodating a fluid treatment component; an installation opening, closable by a closure housing part, for installing the fluid treatment component in the receiving chamber; and a housing connecting section to connect the housing part to the closure housing part. A housing fastening section is provided with which the fluid housing can be fastened to a holding component of the fluid system. An insert is at least partially introduced into the plastic material of the housing part. The insert is provided with a reinforcement region extending with sections thereof in the housing connecting section and is further provided with fastening region extending with sections thereof in the housing fastening section. A fluid treatment system with such a fluid housing is provided.

A filter element for filtering liquids has a folded filter medium with outer fold edges and inner fold edges, wherein the inner and outer fold edges extend along a longitudinal axis of the filter element. A support body is provided with a first support body section and a second support body section, wherein the first support body section is facing the inner fold edges and hugs closely an envelope of the inner fold edges. An envelope of the outer fold edges and the second support body section hug closely at least sectionwise an outer circumferential surface of the filter element.

Filter element and filter arrangement

A filter () for liquid has a filter housing () with at least one hollow filter element (). The filter element at least partially surrounded by a liquid guidance region (). At least one additive chamber () of an additive dispensing device () is disposed on the side of the liquid guidance region () opposite the corresponding exterior side of the hollow filter element () by means of at least one partition (). The at least one partition has at least one dispensing port () by means of which the at least one additive chamber () can be fluidically connected to the liquid guidance region (). The at least one dispensing port () is closed with at least one closure element () at least in the original condition of the additive dispensing device (), this closure element being dissolvable by the liquid to be treated to release the at least one first dispensing port () during operation of the filter ().

A filter device is provided with an annular filter element. A central tube is inserted into the annular filter element so as to delimit an inwardly positioned cavity of the annular filter element. A functional part is inserted into the annular filter element and extends parallel to a longitudinal axis of the annular filter element, wherein the functional part is arranged in radial direction of the annular filter element outward of the central tube. The functional part has a radial inwardly positioned wall facing the central tube. The central tube has a facing wall that is facing the radial inwardly positioned wall of the functional part. The radial inwardly positioned wall of the functional part is positioned parallel to or concentric to the facing wall of the central tube.

Filter device

A filter element is provided with a folded bellows that has a first pleated section with parallel arranged first pleats and a second pleated section with parallel arranged second pleats. The first pleats of the first pleated section are positioned at an angle relative to the second pleats of the second pleated section. The end face edges of the first pleats of the first pleated section adjoin a first clean chamber. The end face edges of the second pleats of the second pleated section adjoin a second clean chamber. The second clean chamber is delimited by a longitudinal side of an edge-side pleat of the first pleated section. The first and second clean chambers are connected to each other. A filter insert with such a filter element is provided.

Pleated filter element

A filter insert piece has a filter element with first and second pleated sections each having parallel pleats. The first and second pleated sections each have an inflow side. A first flat outflow side of the first pleated section and a second flat outflow side of the second pleated section adjoin a common clean chamber of the filter element. A length of the pleats of the first and second pleated sections is such that a spacing of an outwardly positioned pleat end face of the pleats at the first or second inflow side, respectively, relative to the center axis increases or decreases monotonic from pleat to pleat. The respective end pleats of the first and of the second pleated sections have a different length extension measured from the outwardly positioned pleat end face of the first end pleats or the second end pleats relative to the center axis.
