Abstract

Disclosed is an airborne contaminant abatement apparatus (100) comprising an air mover having an air mover inlet and an air mover outlet and configured to create an airflow when operating; a filter disposed in fluid communication with the airflow and configured to remove airborne contaminants therefrom; a supply air passage (120) disposed in fluid communication with the air mover outlet and a vent (130); the vent disposed along at least a portion of a boundary of a plurality of spaces to be occupied, wherein the vent is configured to accelerate the airflow passing therethrough to create an air curtain (200) extending from the boundary; a return air passage (160) configured to receive the airflow at a return port (160) and direct the airflow to the air mover inlet.
