Abstract

A filter element has an, as far as possible, long-term connection between a seal and the frame of the filter element, a filter element having a frame which is assigned a seal is wherein the frame is assigned a mount , in which the seal is accommodated, and fixed, in a form-fitting manner.

Description

technical field [0001] The invention relates to a filter element according to the preamble of claim 1 . Background technique [0002] Cassette filters for high-temperature applications are known from the prior art, which have a sheet metal frame and an aluminum profile frame. [0003] Nowadays, glass cord seals are used for sealing the filter cassettes against the receiving wall in filter installations. The glass cord seal is glued to the filter cartridge. [0004] After the filter cartridge has been used for a longer period of time at elevated temperatures, in particular above 150° C., the adhesive connection may loosen. [0005] Furthermore, the application of adhesive is relatively complex in the manufacture of filter cassettes. Contents of the invention [0006] Against the background described above, the object of the present invention is to provide a filter element in which there is as permanent a connection as possible between the seal and the frame of the filter...
