Separation element and pressure accumulator system

The invention relates to a separation element (10) for separating a fluid from a media stream, in particular an air stream, including at least one hollow cylindrical filter body (12) which acts as a coalescer, and which includes at least one support body (14), and including a radially outwardly situated first filter medium (16) and second filter medium (18), the filter body (12) separating a dirty side (52) from a clean side (50) of the separation element. In addition, the separation element (10) includes a first end disk (20) and a second end disk (22) which are situated on respective opposite end-face sides (24, 26) of the filter body (12), and a receiving recess (38) which is situated centrally on one of the two end disks (20) and protrudes into the interior (30) of the filter body (12). Furthermore, when the separation element is properly installed in a pressure accumulator system (100), the receiving recess (38) is provided for supporting the separation element on a central tube (108) of the pressure accumulator system (100) and sealing off the central tube (108) in a fluid-tight manner. The filter body (12) is provided for the media stream to flow radially through it, the fluid which is separated in the filter body (12) draining from the separation element via an outlet opening (32) in the second end disk (22). The invention further relates to a pressure accumulator system (100) for installing such a replaceable separation element (10).
