Abstract: The invention relates to a filter unit, a filter system (44b) with at least two filter units, and to a motor vehicle with a filter system (44b). A filter bowl (12d-e) of the filter unit is formed by a base and a cover. Embodied in a side wall of the base are at least two access openings to an antechamber or collection chamber (34a-b) in the filter bowl (12d-e). Embodied integrally with the cover is a collection line segment or supply segment (26d-e) that leads from a clean chamber or an unfiltered side antechamber in the filter bowl (12d-e) to at least two open ends (28l). The inventive filter system (44b) has at least two inventive filter units, and fluid may flow through their filter elements (30, 30a-d), which are switched in parallel. The invention facilitates the space-saving arrangement of filter units and filter systems (44b) in constricted and/or complexly shaped installation spaces, especially in motor vehicles.

Abstract: A humidification device is provided with at least one stacked unit of water vapor-permeable membranes and of support frames. The support frames are stacked on each other. The membranes each are positioned between two of the support frames, respectively, and have edges clamped between the two support frames. The membranes are arranged parallel and spaced apart relative to each other. Between the two support frames, a supply air flow path extends on a first lateral face of the membrane and, angularly displaced to the supply air flow path, an exhaust air flow path extends on a second lateral face of the membrane facing away from the first lateral face. A flow opening of the supply air flow path and a flow opening of the exhaust air flow path are delimited by the two support frames and extend parallel to a plane of the membrane clamped between them.

Abstract: A blood filtering device has a filtration section with filter medium separating raw side and clean side. A first communication path connects raw side and a first variable blood reservoir volume; a second communication path connects raw side and a second variable blood reservoir volume coupled to a receptacle. When varying the first variable blood reservoir volume, blood contained therein flows through first communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through second communication path into the second variable blood reservoir volume. When varying the second variable blood reservoir volume, blood contained therein flows through second communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through first communication path into first variable blood reservoir volume.
