The invention relates to a filter (10) comprising a container (12) extending along a main axis (A1) and filter plates (24) arranged parallel to the main axis (A1) and disposed in a containment volume (22) of the container (12) in a
star pattern, each of the filter plates (24) comprising at least one
filter element (34) connected to a collection tube, the filter (10) comprising an external collector (28), each of the collection tubes (36) comprising an end section extending in the containment volume (22) of the container (12) along a secondary axis parallel to the main axis (A1), the end section of each of the collection tubes being fluidically connected to the external collector (28) through a through passage formed in a main wall (20) of the container (12), each passage extending through the main wall (20) along the secondary axis.
