Abrégé

The present invention relates to an air curtain device for realising an air curtain, with in use a substantial vertical air flow, and a method for providing such air curtain. The air curtain device according to the invention comprises: - a housing substantially extending along an opening in a wall and comprising air displacing means; - at least one air inlet for supplying air to the housing; - at least one primary outflow opening configured for achieving a primary air curtain with a primary height, a primary length, and a primary width, the primary outflow opening extending substantially parallel to the opening at a certain distance thereof; and - at least one secondary outflow opening configured for achieving at least one secondary air curtain substantially perpendicular to the plane defined by the opening such that it substantially closes a gap resulting from providing the air curtain at the certain distance of the opening in the wall and in use provided at or close to an end of the primary air curtain, such that in use in a horizontal plane an L-shaped or U-shaped air curtain is achieved.
