Sterile blow moulding machine with non-sterile media supply

An apparatus for the shaping of plastics material pre-forms into plastics material containers, comprising:

• a plurality of shaping stations which are arranged on a movable carrier, wherein the shaping stations each have blow moulds which are used for receiving the plastics material pre-forms and inside which the plastics material pre-forms are capable of being shaped into the plastics material containers, and wherein the plurality of shaping stations have in each case stressing devices which are movable relative to the plastics material pre-forms and which act upon the plastics material pre-forms arranged in the blow moulds with a sterile flowable medium to expand them;
• a clean room, inside which the shaping stations are conveyed, wherein this clean room is arranged or demarcated from the environment by means of at least one wall;
• an actuating valve;
• and
• at least one supply device connected to said actuating valve and configured for supplying a flowable control medium to at least one of the plurality of shaping stations, said at least one supply device extending at least locally inside the clean room, wherein said at least one supply device is sealed off from the clean room in such a way that the flowable control medium is also capable of being conveyed as a non-sterile medium to the shaping station, wherein said at least one supply device supplies the sterile medium to said plurality of shaping stations only for the expansion of the plastics material pre-forms in said plurality of shaping stations, and the non-sterile medium is a control medium for controlling the actuating valve.
