Abstract: A breathing zone ventilation system for providing a protective air barrier between closely spaced individuals within a local environment. The breathing zone ventilation system includes a plurality of seats. An air control module has a housing defining an interior cavity, a blower, and at least one air tray stage. The housing has an inlet in communication with an air inlet and outlet. The blower, contained within the housing, is configured to develop a high velocity airflow into the air inlet, defining a downdraft air curtain. The at least one air tray stage is disposed between the blower and the outlet and has a frame defining an air tray enclosure. A plurality of baffles are disposed in a spaced apart relation within the air tray enclosure to define a labyrinth pathway between the blower and the outlet. The outlet may be configured to vent clean air within the local environment.
