Embodiment Construction

[0025] refer to figure 1 and figure 2 , The air filter device according to the invention comprises a housing 1 having relatively large front walls 2 and 2' connected to each other by a relatively narrow peripheral wall 3. On the peripheral wall 3 , a raw space inlet 4 and a clean space outlet 5 are arranged, wherein the inlet 4 and the outlet 5 are separated by a filter element 6 arranged in the housing 1 .

[0026] refer to image 3 , the filter element 6 comprises frontal chassis 7 and 7', which are connected to each other at their respective edge regions by an approximately circumferential filter wall 8, which is folded into an approximate star shape in plan view of the chassis 7, 7', wherein The pleats extend perpendicular to the chassis 7, 7'. This filter wall 8 passes through the long sides 19 of the chassis 7 and 7' through a through hole 9 provided in the side disc 20 and firmly connected to the filter wall 8 and the chassis 7, 7'. In the assembled state...

Abstract

A filter arrangement may include a housing having two front walls substantially extended on both sides of a housing center plane and a circumferential wall connecting the front walls. The housing may include an untreated space inlet and a clean space outlet. A filter insert may be arranged between the inlet and the outlet and include two bottom discs that are adjacent to the side walls in the assembled state of the filter insert. The filter insert may include a filter wall extending between and connecting the bottom discs. The filter wall may extend substantially orthogonal to the housing center plane. A lateral disc may define an opening configured to be tightly connected to at least one of the inlet and the outlet. The front walls may be coupled to the bottom discs in the assembled state of the filter insert through interacting profile parts arranged on at least one of the front walls and the bottom discs into a double wall.

Description

technical field [0001] The invention relates to a filter device, in particular an air filter device, having a housing comprising two large front walls extending substantially on either side of a central plane of the housing and a peripheral wall substantially perpendicular to the housing central plane and connects the front wall with the raw space inlet and the clean space outlet, the filter unit has a filter element effective between the raw space inlet and the clean space outlet, said filter element consists of two chassis and a filter wall, so The chassis is adjacent to the front wall in the assembled state of the filter element, the filter wall connecting the edge area of ​​the chassis substantially perpendicular to the center plane of the housing, being pierced by a through hole capable of being firmly connected to Said untreated space entrance or clean space exit. Background technique [0002] Such air filters are used as standard in large diesel engines of commercial...
