The drainage layer cooperates with an adjacent drainage layer and/or has individual line elements (33) that form a mesh or grid structure. Those line elements are arc-shaped or curved at least to some extent.
A contamination indicator is for filter elements (12) for fluids that are replaceably housed in a filter housing (2). The indicator has a fluid-conveying connection (58) to the interior of the housing (2) and possesses an indicating device (52) providing information concerning the degree to which the filter element is contaminated (12). A temperature-dependently active actuation device (50) is connected upstream from the indicating device (52) in the direction of fluid inlet. By the actuation device, the indicating device (52) is activated when the fluid temperature has reached a predefinable threshold value.
A filter medium for cleaning fluids includes a filter layer (9) formed from a filter material in a pleated web with a longitudinal direction (X) and a transverse direction (Y). A plastic grid (10) forms a support layer, bears against the filter layer (9) and has linear elements (12, 14) delimiting through openings (16) between them. Two groups of linear elements (12, 14) extend approximately at right angles to one another and delimit rectangular through openings (16). The linear elements (14) having a smaller diameter (d2) are in direct contact with the filter layer (9). The linear elements (12) having a larger diameter (d1) and having a greater spacing from one another relative to the filter layer (9) rest on the smaller diameter linear elements (14).
