Abstract

An air passage device for installation into a mounting opening in a wall of a housing for components generating waste heat, such as a switching box, has a base housing with a fan support for a fan and a design cover with a fan grid having sheet elements. At least one swivellable sheet element or at least one flexible, tongue-shaped side wall section, separated from the remaining side wall surface of the side walls of the design cover by slits running transversely to the longitudinal direction of the side wall, is formed in the region of the upper side wall of the design cover facing away from the swivel axis for swivelling the design cover. The sheet element and the tongue-shaped side wall section are constructed as a detachable and lockable detent connection, able to be actuated by a finger, between the design cover and the base housing.
