Abstract

The present invention relates to an air filter arrangement and a method for manufacturing such air filter arrangement. The air filter arrangement comprises an air channel (2), a first air filter (8) mounted in the air channel (2), which first air filter comprises a filter frame (10) provided with at least one passage (10a) for through flow of air, and a filter body (11) comprising electrostatically chargeable fibres which are attached to the filter frame (10) such that the filter body (1 1) obtains an extension from the filter frame (10) to a position located at a distance from and downstream the filter frame (10) with respect to the flow direction of the air through the air channel (2). The air filter arrangement comprises a second air filter comprising a filter cloth which, in a mounted state, is adapted to extend across the air channel (2) such that it is flown through by air flowing in a substantial longitudinal direction in the air channel (2), and that the second airfilter is mounted in the air channel (2) in a position located downstream the first air filter (8) with respect to the flow direction of the air through the air channel (2).

Description

technical field

[0001] The present invention relates to an air filter device and a method of manufacturing such an air filter device. Background technique

[0002] The air filter device includes an air channel, a first air filter installed in the air channel, wherein the first air filter includes a filter frame and a filter body, the filter frame is provided with at least one filter for air flow channels, the filter body comprising electrostatically chargeable fibers attached to the filter frame such that the filter body achieves a predetermined flow direction from the filter frame to the air channel relative to the flow of air through the air channel at a distance from the filter frame An extension at a position some distance downstream.

[0003] When air flows through a first air filter of the type described above, the fibers in the filter body have mutual movement so that they rub against each other. This friction and friction as the airflow passes through the fibers ke...
