Abstract: A humidifier having a housing that extends along an axial direction, the housing having a first inlet, a first outlet, a second inlet and a second outlet, and a membrane unit being arranged in the interior of the housing. The first inlet and the first outlet are in flow connection with each other by means of a first flow path, and the second inlet and the second outlet are in flow connection with each other by a second flow path. The membrane unit is cylindrical and has a plurality of hollow fiber membranes arranged side by side. The membrane unit is outwardly surrounded at least in part by a first chamber, and the first chamber is outwardly surrounded at least in part by a second chamber separate from the first chamber. The first chamber and the second chamber are in flow connection with each other via one or more throttle slots.

Abstract: The invention relates to a liquid separator for separating liquid from a gas-liquid mixture, having a housing, an inlet, an outlet, a flow path connecting the inlet to the outlet, and a separating device, arranged in the flow path, for liquid separation, wherein a wall body is attached to the inner side of a housing portion adjoining the outlet, surrounds an annular collar projecting into the housing from the outlet, and extends towards a liquid outlet, wherein the wall body, together with a wall of the housing, defines a flow channel so that liquid collected at the outlet can be discharged through the flow channel via the liquid outlet.

Abstract: A liquid separator (10) for separating liquid from a gas-liquid mixture has a housing (12), an inlet (14), an outlet (16), a flow path (18) connecting the inlet (14) to the outlet (16), and a separation device (20), arranged in the flow path (18), for liquid separation, wherein a diverting element (22) is arranged adjacent to the separation device (20). Said diverting element separates an inlet region (24) of the housing (12), into which the inlet (14) opens, and an outlet region (26) of the housing (12), from which the outlet (16) opens, from one another, wherein the flow path (18) extends from the inlet region (24) via a low-flow region (46) into the outlet region (26).
