  • FIG. 10 shows a perspective view of a second filter element housing part 20.
  • a fluid inlet 21 and a fluid outlet 22 are provided in the embodiment shown in FIG. 9.
  • a circumferential sealing surface 25 can be seen on the first filter housing part 20, into which a drainage opening 23 opens substantially flush. Also indicated are the concentric circumferential sealing lines 27, between which the drainage opening 23 is located.
