Abstract

The invention relates to a filter system (100) comprising a housing (110), a fluid inlet (102) formed in a housing wall (112), a fluid outlet (108) formed in a housing wall (120), a primary filter element (50) and a secondary filter element (10), both being accommodated in the housing (110). The secondary filter element (10) is arranged downstream the primary filter element (50) on a stand pipe (150), the stand pipe (150) being rigidly connected to one of the housing walls (120), the inside of the stand pipe (150) being in fluid connection with the fluid outlet (108). The secondary filter element (10) comprises a filter medium (16) forming a body (36) having at least one longitudinal seam (18) along a longitudinal axis (L) and an end cap (20) at its top region (12), The secondary filter element (10) and the stand pipe (150) are mutually connected at one of their top regions (12, 152) by connection elements (22, 156). The secondary filter element (10) and the stand pipe (150) are configured with mutual self-positioning elements (30, 180) to arrange the secondary filter element (10) on the stand pipe (150) in a defined rotational position with respect to one or more struts (170) of the stand pipe (150).The invention further relates to a secondary filter element (10) for such a filter system (100).
