CA 2344066

The invention relates to a device and a method for separating at least two spatial areas (1, 2) and for reducing the transmission of airborne particles between the spatial areas in order to protect persons and/or products (26) from the airborne particles, the person being located at least in part in the first spatial area (1) and the products (26) in the second spatial area (2), and at least one planar air jet (13) of purified air being used for the separation, wherein at least one low-turbulence displacement stream (14) is generated with purified air near the at least one air jet (13) in at least the second spatial area (2), said at least one displacement stream being directed in essentially the same direction as the at least one air jet (13).

L'invention concerne un dispositif et un procédé permettant de séparer au moins deux zones spatiales (1, 2) et de réduire le transfert des particules en suspension dans l'air entre ces deux zones spatiales en vue de protéger les personnes et/ou produits (26) des particules en suspension dans l'air, la personne se trouvant au moins partiellement dans la première zone spatiale (1) et les produits (26) dans la deuxième zone spatiale (2). Pour cette séparation, on utilise au moins un jet plat (13) d'air purifié. L'invention est caractérisée en ce que l'on produit à proximité du ou des jet(s) d'air (13) au moins un courant de déplacement (14) pauvre en turbulences dans au moins la deuxième zone spatiale (2), le ou les courant(s) de déplacement étant dirigé(s) essentiellement dans la même direction que le ou les jet(s) d'air (13).
