A filter arrangement for cleaning a gaseous medium consisting of a number of layers of filter elements (3, 4) in the form of sheets. These are enclosed within a casing (2) and are situated at a certain distance from one another and exhibit an inlet side, on which the medium flows into the filter elements, and an outlet side, on which the medium flows out of the filter elements. The filter elements are in communication via a first space (13, 14) on their inlet side with an inlet to the casing, and are in communication via a second space (15, 16) on their outlet side with an outlet (6) from the casing, with said first and second spaces (13, 14, 15, 16) being defined for each layer of filter elements by an inclined wall (17, 20, 21) such that the first space is given a successively decreasing cross-sectional area, when viewed from the inlet (5), whereas the second space is given a successively increasing cross-sectional area. |
