Abstract: A microplastic filter (also referred herein as fluid filter) for a washing machine has a filter housing, a first filter screen, a second filter screen, an inlet opening 16, and an outlet opening. The inlet and outlet openings communicate with each other through the first filter screen to define a direction of fluid flow. The first filter chamber has a retentate outlet, is particularly easy to handle if the second filter screen is arranged in a cavity of the filter housing, the inlet and outlet openings communicate with each other through the second filter screen, and the retentate outlet is arranged on a side of the second filter screen that faces the fluid flow.

Abstract: A gas filter that includes a filter medium configured to filter a gas flow propagating from an upstream facing side through the filter medium to a downstream facing side. The filter medium includes a capacitor with a first electrode, a second electrode, and a dielectric medium. The gas filter also includes a first electrical contact and a second electrical contact such that the first electrical contact is electrically connected via a first resistor to a branching point and the second electrical contact is electrically connected via a second resistor the same branching point. Further, the first electrode is preferably electrically connected to such branching point and the second electrode is preferably electrically connected to the second electrical contact.

Abstract: A rotor of a centrifugal separator, including a central shaft, a plurality of identical discs arranged in a stack on the central shaft, the central shaft having on an outer circumference an engagement contour for a rotationally fixed, axially slidable engagement with a corresponding contour on an inner circumference of the discs, the engagement and corresponding contours engageable with one another in multiple rotational positions at a circumferential distance from one another, and each disc having spacing elements situated at a disc circumferential distance from one another, which spacing elements hold each two adjacent discs at an axial distance from one another, forming an intermediate flow gap having a gap dimension. The spacing elements are formed and configured such that, via different rotational positions relative to one another of adjacent discs, at least two different axial dimensions of the flow gap between adjacent discs may be set.
