Inlet and outlet end regions (14,15) are provided. The air flow duct valves, esp. respectively two check valves (22,23,25,31) work automatically in opposite directions. The check valves are operated by the flow direction. On one side a closed air circulation (30) is connected with the outside air. On the other side another closed air circulation (17) is provided, connected with the chamber, the air of which is to be dried.
