Abstract: A filter system (100) having 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). The secondary filter element (10) is arranged on a stand pipe (150) rigidly connected to one of the housing walls (120). The secondary filter element (10) includes 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 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) in a defined rotational position with respect to one or more struts (170).

Abstract: An outdoor air purifier includes a housing including at least one housing cover part, a mounting base, at least one flow inlet for outdoor air to be purified, at least one flow outlet for cleaned air, and an inner clean air space, a fan having a standing rotational axis and arranged within the housing, wherein the at least one flow inlet is arranged radially with regards to the standing rotational axis, and the at least one flow outlet is arranged axially with regards to the standing rotational axis, and at least one filter element at least partially surrounding the inner clean air space. The fan is displaced axially from the mounting base and is in fluid connection with the inner clean air space. The at least one filter element extends essentially parallel to the standing rotational axis.

Abstract: A filter system (100) having 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). The secondary filter element (10) is arranged on a stand pipe (150) which is rigidly connected to one of the housing walls (120). 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). The filter body (36) has a first edge (13) at one region (12) which is curved in an initial unwound state of the filter medium (16) and straight in a final wound state of the filter medium (16) forming the filter body (36) and a second edge (15) at the opposite region (14) of the filter body (36) with respect to the longitudinal axis (L) which is straight in an initial unwound state of the filter medium (16) and curved in a final wound state of the filter medium (16) forming the filter body (36). A method of manufacturing is also disclosed.
