摘要

Filter unit comprises a filter housing consisting of an upper part inserted into a lower part in such a way that the filter element (6) lies in a peripheral filter element edge region (13) on one side on a bearing surface of the upper part and on a bearing surface (17) of the lower part on the other side on the other side. Filter unit comprises a filter housing consisting of an upper part (2) inserted into a lower part (4) in such a way that the filter element (6) lies in a peripheral filter element edge region (13) on one side on a bearing surface of the upper part and on a bearing surface (17) of the lower part on the other side on the other side. The housing parts are pressed together to form a seam (12) between the bearing surface of the upper part and the filter element edge region so that the seam seals the filter chamber (3) from the filtrate chamber (5). The unit has a laser welded joint (10) between an outer edge (8) of the upper part and an inner edge (9) of the lower part.
