Abstract
The invention relates to a filter element (F), particularly for the static or dead-end filtration of fluids, comprising an inner, essentially hollow supporting core (10) and at least one filter layer (12–14) placed thereon. The inner supporting core (10) is formed as a single piece together with a first end plate (20) and with a second end plate (30). The first end plate (20) comprises a connecting piece (22), which is provided therewith as a single piece and which is fluid-connected to the supporting core (10). The second end plate (30) has a seat (32), which is formed therein, is fluid-connected to the supporting core (10) and is adapted to the shape of the connecting piece (22) whereby enabling a connecting piece (22) of a second structurally identical filter element (F) to be at least partially inserted into the seat (32) in order to establish a fluid connection between the supporting cores (10) of the filter elements (F). The invention also relates to a filter device for fluids comprising a housing, which has an inlet for the fluid to be filtered and an outlet for the filtrate, and comprising two or more inventive filter elements (F) that are interconnected via the respective …
