Filter sealing system

Abstract

The invention relates to a filter element for a fluid stream flowing in at the front side, in which a machine for sealing an inflow and an outflow side of the filter element in a filter housing part includes an annular sealing part. A peripheral seal in the form of an annular collar is provided on a frontal side of the filter element, connected via an axial section of the element casing surface. Part of the collar extends axially over the frontal side of the element, and a frame element is connected with an axial protuberant portion of the collar. As a result, the frame element supports the collar against forces acting radially outwards.

Description

technical field

[0001] The invention relates to an air filter element according to the preamble of claim 1 . Furthermore, the invention relates to a method according to the preamble of claim 11 for servicing an air filter with an air filter element according to the invention. Background technique

[0002] Filter elements with axial flow through are used in many areas in which a gas or a liquid is to be filtered. Furthermore, these elements can be used in any type of filter housing and must be replaced or cleaned as required after reaching a certain load or after prescribed maintenance intervals. EP1159052 shows a filter element with a frame structure which is annularly connected to the housing surface of the filter element in the region of one of the end faces and has an extension which protrudes axially beyond the end face . On the extension, a sealing element is also arranged, which element is positioned at least partially around the outer peripheral surface of the exte...
