Abstract: An apparatus for treating containers, includes a transport unit that transports the containers through a clean room and a plurality of treatment elements arranged within the clean room. The clean room is separated by a plurality of walls against an environment. The treatment elements are movable, for example, rotatable in relation to a predefined axis and movable in the direction of this axis, in order to attach closure caps onto the containers. Each of the treatment elements is arranged on a carrier that extends through a wall of the clean room, and each has a sealing unit in order to seal at least one movement of the carrier. The sealing unit includes a receptacle for receiving a liquid separating medium and a wall element movably arranged within the separating medium. At least one sealing unit has an inlet via which a cleaning medium can be supplied to the sealing unit.
