Abstract: A separation device for separating liquid from gas has a separation element with housing, housing cover with housing cover thread, and filter element arranged therein. A first gas passage arranged centrally relative to a mounting axis of the separation element at a connector device has the housing cover thread assigned thereto. A second gas passage is arranged radially outside the first gas passage. A connection element connecting the separation element to the connector device has a conduit and a connection element thread to which the housing cover thread is screwed. A circumferential element adjoining the connection element thread extends axially into the separation element. Connection element thread and circumferential element surround the conduit. A fluid channel extends axially between conduit and circumferential element.
