Abstract
A screen for improving the environment of separate working areas in a working place having a plurality of such working areas, e.g. a factory floor, a workshop, an office or the like, is provided with a mechanism for connecting the screen to an air-supply line and exhibits at least one perforated side surface. The screen is hollow and accommodates a perforated supply and distributing pipe for fresh air. So as to evenly distribute the air, the pipe in a preferred embodiment has a number of nozzles which project into the path of the main-flow in the pipe and deflect uniform part flows therefrom in a direction substantially transversally of the direction of the main-flow and at substantially the same speed as the speed of the main-flow before the first nozzle. The screen may serve as a combined acoustic and air-supply screen which enables personnel to work close to the screen without being subjected to draughts.
