Rotating coalescing directional fluid drainage and directional gas outlet

There is described a rotating coalescer which has a separating device for spinning off, coalesced liquid. The separation device preventing re-entrainment of liquid in a stream of filtered gas. The rotating coalescer includes a rotating filter element or a Koaleszenzkegelstapel, which is arranged within a rotating Koaleszergehauses respectively. The outer surface of the rotating filter element or the outlet of the Koaleszenzkegelstapels is offset from the inner surface of the rotating Koaleszergehauses. The gap between the rotating filter element or the Koaleszenzkegelstapel and the rotating Koaleszergehause allows accumulation weggeschleuderter, coalesced liquid, for example oil, so that it can flow to the inner surface of the rotating Koaleszergehauses, and allows filtered gas, e.g., air, escape through a clean gas outlet the rotating Koaleszergehauses.
