Abstract
An air barrier system is disclosed that allows the isolation of a central volume or one volume from another without the use of physical barriers. Toroidal vortices are formed at opposing end or ends of the volume to be isolated and prevent transport inward and outward. Contemplated applications include air curtains, oxygen tents, cleanrooms and testing chamber apparatus.
