Abstract
The invention relates to a method and a device for separating at least two physical areas (1, 2) and for reducing the transmission of air-borne particles between said physical areas so as to protect persons and/or products (26) from said air-borne particles. The persons is located at least partly in the first physical area (1) and the products (26) in the second physical area (2) and at least one flat jet (13) of purified air is used to separate the two areas. The invention is characterized in that at least one low-turbulence displacement air stream (14) of purified air is generated at least in the second physical area (2) near the at least one air jet (13) and said at least one displacement air stream is directed primarily in the same direction as the at least one air jet (13).
