Filter arrangement for an electric discharge machine, featuring - at least one hollow-cylindrical filter element designed for cleaning a dielectric of the electric discharge machine, and - at least one dielectric inlet centrally disposed at a front face of the filter arrangement having at least one axial rotationally symmetric connection means for connecting a dielectric feed connection element of the electric discharge machine, wherein the filter arrangement is designed such that the dielectric to be cleaned flows through the filter element from radially inward to radially outward, wherein the filter arrangement is designed as a so-called "stand-alone filter" not requiring a pressure vessel, in such a way that, for accepting the differential pressure, a fluid-permeable support body designed as an outer casing having fluid passage openings is disposed externally around the filter element, wherein an end disc is disposed at each of the front faces of the filter arrangement, wherein the end discs support the support body, - at least one identification element having filter-specific data, which is secured at the front face of the filter arrangement against loss, wherein the identification element is disposed at a radial distance from the dielectric inlet, characterized in that - the rotationally symmetric connection means is an axial hose connection extension arranged for connecting a dielectric feed connection element designed as a hose quick coupling element, and - at least one adapter form-fitting element is secured against loss at the front face of the filter arrangement at a radial distance from the dielectric inlet, wherein for connecting the filter arrangement to the electric discharge machine, the adapter form-fitting element of the filter arrangement is detachably connectable to an adapter form-fitting element of the electric discharge machine, wherein, in a closed position of the adapter form-fitting elements (40, 220), the axial dielectric inlet of the filter arrangement is connectable in a fluid-tight manner to the dielectric feed connection element of the electric discharge machine, and wherein the adapter form-fitting element of the filter arrangement is designed such that it allows the closed position of the respective adapter form-fitting elements (40, 220) only in a defined angular position and thus determines the position of the identification element relative to the adapter form-fitting element of the electric discharge machine. - at least one hollow-cylindrical filter element designed for cleaning a dielectric of the electric discharge machine, and - at least one dielectric inlet centrally disposed at a front face of the filter arrangement having at least one axial rotationally symmetric connection means for connecting a dielectric feed connection element of the electric discharge machine, wherein the filter arrangement is designed such that the dielectric to be cleaned flows through the filter element from radially inward to radially outward, wherein the filter arrangement is designed as a so-called "stand-alone filter" not requiring a pressure vessel, in such a way that, for accepting the differential pressure, a fluid-permeable support body designed as an outer casing having fluid passage openings is disposed externally around the filter element, wherein an end disc is disposed at each of the front faces of the filter arrangement, wherein the end discs support the support body, - at least one identification element having filter-specific data, which is secured at the front face of the filter arrangement against loss, wherein the identification element is disposed at a radial distance from the dielectric inlet, - the rotationally symmetric connection means is an axial hose connection extension arranged for connecting a dielectric feed connection element designed as a hose quick coupling element, and - at least one adapter form-fitting element is secured against loss at the front face of the filter arrangement at a radial distance from the dielectric inlet, wherein for connecting the filter arrangement to the electric discharge machine, the adapter form-fitting element of the filter arrangement is detachably connectable to an adapter form-fitting element of the electric discharge machine, wherein, in a closed position of the adapter form-fitting elements (40, 220), the axial dielectric inlet of the filter arrangement is connectable in a fluid-tight manner to the dielectric feed connection element of the electric discharge machine, and wherein the adapter form-fitting element of the filter arrangement is designed such that it allows the closed position of the respective adapter form-fitting elements (40, 220) only in a defined angular position and thus determines the position of the identification element relative to the adapter form-fitting element of the electric discharge machine.
