Embodiment Construction

[0031] figure 1 A filter module is shown in perspective, comprising a base body 1 with a grid 2 and a support 3 for a filter element 11 . The carrier 3 allows the filter element 11 and the grid 2 to be inserted together as a structural unit in a filter housing 10 for an air intake system. The filter element can be secured against falling on the grid 2 and can be fixed together with the grid 2 in the filter housing 10 of the air intake system at the installation site. The fitter does not have to carry out subsequent trimming of the filter element 11 or of the grid 2, since they are optimally matched to each other conveniently at the factory.

[0032] The bearing means 3 is formed on the grid 2 by means of the webs 4 and has clips 5 which protrude from the respective web 4 . In this way, a filter element 11 , for example a flat filter material or a flat layer, can be clamped to the grid 2 . The clips 5 then press the filter element 11 against the grid 2 .

Abstract

The invention relates to a filter module for insertion into a filter housing (10), comprising a base body (1), which has a grating (2) and receiving means (3) for a filter element (11). The filter module solves the task of simplifying the installation of a grating (2) and a filter element (11), and reducing installation costs.

Description

technical field [0001] The invention relates to a filter module for insertion into a filter housing. Background technique [0002] Filter housings and air ducts are usually connected upstream of air conditioning units or fans in the interior of motor vehicles. Various types of filter elements are used in filter housings for suction systems in order to filter, for example, suspended matter, particles and / or unpleasant odors from the suctioned air. Also, for engine supply air filtration, consideration must also be given to ensuring that the air drawn into the car engine has a sufficiently good purity. [0003] For this reason, a grid is often connected upstream of the filter element in question for the mechanical separation of coarse particles, such as leaves, stones or coarse dirt. As a grid, a so-called sheet protection net can be used. [0004] A disadvantage of a system constructed in this way is that the filter element and the grid must be structurally adapted to each ...
