Abstract:
Dynamic separation device comprising:at least one buffer zone with controlled atmospher configured to connect a first zone and a second zone;first dynamic confinement means provided between the at least one buffer zone and the first zone to be configured to create a first air curtain between the at least one buffer zone and the first zone;second dynamic confinement means provided between the at least one buffer zone and the second zone to be configured to create a second air curtain between the at least on buffer zone and the second zone; andeach of the first and second air curtains comprising a first relatively slow clean air jet and a second relatively fast clean air jet, the first relatively slow clean air jet including a tongue which substantially separates the at least one buffer zone from the first or second zones, the second relatively fast clean air jet being configured to flow on a side of the at least on buffer zone and next to the first relatively slow clean air jet in a same direction as the first relatively slow clean air jet.
