Abstract: A water separating screen for a filter element in a liquid filter, the water separating screen including: a screen fabric having end faces; and a fabric carrier; a screen fabric arranged on the fabric carrier and encircling a longitudinal axis, the screen fabric having axial end faces, the longitudinal axis defining an axial direction; wherein the fabric carrier in an area between the end faces exclusively has longitudinal struts, which at least substantially extend in the direction of the longitudinal axis and which are elastic in a radial direction.

Abstract: An annular filter element, including: a filter medium having circumferentially closed about an axis and extended along the axis, the axis defining an axial direction; wherein the filter medium has a radially outer flow face and a radially inner flow face, the radially inner flow face surrounding an inner clean space in the filter element; wherein the filter element is through-flowable radially from a radial outside to a radial inside of the filter element; a water separation screen inserted into the clean space, the water separation screen formed separately from the filter element, the water separation screen connected to the filter element or to a component situated at the filter element.

Abstract: A filter element (32) and a filter device (10). The filter element (32) can be arranged in a filter housing (16) of the filter device. The filter element (32) has an annular closed filter medium (34) connected with at least at one end face with an end member (36, 38). An annular anti-drain membrane (44) opens and closes at least one fluid opening (26) of the filter housing (16) and is arranged on the side of the at least one end member (38) that is facing away from the filter element (34). The surface of the contact section (60) of the anti-drain membrane (44) has at least one relief-like adhesion disturbance area (64) for disturbing an adhesion of the anti-drain membrane (44) to the contact section (60).

Abstract: A compact filter has a compact filter element for exchangeable use in a filter housing and the compact filter element has a filter body of a web-shaped filter medium. The web-shaped filter medium has at least one flat filter medium web and one corrugated filter medium web that are placed onto each other and at least partially connected to each other by ultrasonic welding. At least one of the flat and corrugated filter medium webs is a composite filter medium web of at least two components, wherein at least one component is a synthetic material and one component is a non-synthetic material. The non-synthetic material is a plant-derived material and forms a support of the composite filter medium web and the synthetic material is a synthetic layer applied on the support.
