Abstract

Air-extraction device for conditioning the atmosphere of a railway vehicle and for temporarily pressurising this atmosphere. It comprises at least one axial fan (1), the blades (10) of which have symmetrical leading-edge and trailing-edge profiles, and enabling it to rotate in both directions, and a drive motor (2) capable of rotating in both directions. <IMAGE>
