摘要

Invention Patent: B "PROCESS AND PROVISION FOR THE PROTECTION OF PERSONS AND/OR PRODUCTS AGAINST PARTICULAR AIR CARRIED" D . This invention refers to a device and a process for the separation of at least two physical spaces (1, 2) and for the reduction of the transmission of airborne particles between physical spaces, for the protection of persons and/or products (26) from airborne charged particles where the person is at least less partly in the first physical space (1),and products (26) in the second physical space (2),in which at least one purified air laminar air jet (13) is used for separation, characterised by the fact that it is generated with purified air in at least the second physical space (2) at least one low turbulence displacement air current (14) near at least the single air jet (13),where the single displacement air current is directed predominantly in the same direction as the single air jet (13).
