Abstract:
(EN) There is disclosed a multi-chamber enclosure (1) which comprises an external frame (2) and a flexible cover (30) suspended from and hanging within the frame, the cover including a first opening (48) for providing access to and from a clean environment and a second opening (43) for providing access to and from a hazardous environment, and at least one flexible partitioning wall (40) which divides the enclosure into two or more chambers and which includes an aperture therein for providing access between the internal chambers. Two closure flaps (41a) and (41b) overlap the aperture in the partition wall (40), one being located on the upstream side of the partitioning wall and the other being located on the downstream side with respect to the intended direction of through flow of air through the enclosure in a direction from the clean end of the enclosure to the dirty end.
(FR) Enceinte (1) à chambres multiples comprenant un cadre externe (2) et une couverture souple (30) suspendue au cadre à l'intérieur duquel elle pend, la couverture comprenant une première ouverture (48) destinée à assurer l'accès à un environnement propre et hors de celui-ci, une seconde ouverture (43) destinée à assurer l'accès à un environnement très dangereux et hors de celui-ci, ainsi qu'au moins une paroi (40) de cloisonnement souple divisant l'enceinte en deux chambres ou plus, une ouverture étant ménagée dans ladite paroi, assurant l'accès entre les chambres internes. Deux volets de fermeture (41a) et (41b) chevauchent l'ouverture se trouvant dans la paroi (40) de cloisonnement, un étant situé du côté amont de la paroi de cloisonnement, l'autre étant situé du côté aval par rapport à la direction voulue du courant d'air de passage à travers l'enceinte, dans une direction allant de l'extrémité propre de l'enceinte jusqu'à l'extrémité sale.
