A door arrangement for tightly closing a door opening comprises a door frame, a door which, when closed, is arranged in the door frame, and inner and outer sealing lips. The inner and outer sealing lips run next to each other along a periphery of the door opening between a first surface of the door and a second surface of the door frame, wherein the first and second surfaces face each other. The inner and outer sealing lips bound a space formed between them. The door arrangement further comprises a pressure-reducing device configured to reduce pressure in the space. |
