  • the fastening elements 25 to 27 of the respective filter element 14 are threaded into the receiving openings 41 to 43 of one of the connection openings 37 to 40 and the filter element 14 is rotated counterclockwise relative to the filter element adapter plate 18 in the orientation of FIG. 16.

Due to the asymmetrical arrangement of the fastening elements 25 to 27 and the receiving openings 41 to 43 results in a key-lock system, whereby not suitable filter elements can not be mounted on the filter element adapter plate 18. With the aid of the filter arrangement 12, a large and difficult-to-handle conventional filter element can be replaced with a plurality of individual filter elements 14 and the filter element adapter plate 18. With the help of the compressed sealing element 28, a reliable sealing of the respective filter element 14 with respect to the filter element adapter plate 18 is ensured.
