Abstract

Device for maintaining an area free of dust and bacteria in a room by means of several air curtains surrounding the area under a simultaneous supply of ventilation air to the said area separated by the curtains, said device having means for an even distribution of the ventilation air supplied to the interior of the area, while the means for producing the air curtains surrounding the area comprise one or more exhaust nozzles located next to each other to produce a corresponding number of air curtains, whose air is then discharged together with the ventilation air supplied to the area, said exhaust nozzles being placed in a wall, which faces the area, of a distribution channel that surrounds it and has several sides, preferably straight, that they delimit it, the nozzles being at a corresponding number of angles, characterized by the fact that there is an impulse organ ion to separately produce a burst of air preferably much more powerful at each angle between the pair-matched exhaust nozzles to balance, by ejector action, the contraction forces of two adjacent sides of the air curtain and to secure a curtain full air around the area also at the angles.
