摘要

A system comprising a, preferably designed as a holding frame (1), holding construction with a, preferably circumferential, the contact face (2), which can be inserted into the holding structure, preferably by a filter frame comprise tes, filter element (4) as well as at least one the filter element (4) in its fixing position directly or indirectly against the contact surface (2), preferably in a sealing manner, fixing the fixing element (5), characterized in that at least one fixing element (5) as a about a pivot axis (7) rotatably mounted eccentric lever is formed, wherein the eccentric lever from its not fixing position n in at least two different fixing positions and wherein the eccentric lever can be displaced in the various fixed location for a varying width of the displacement of the part to be fixed filter element (4) in the direction (arrow 8) of the contact surface (2) causes.
