Abstract

Filtermodul für Reinraumdecken und -wände oder dergleichen, das entweder von einem Druckraum (26) und einem diesem vor­ gelagerten, auf Unterdruck gehaltenen Decken- bzw. Wand­ hohlraum (9) gebildet ist oder von einem mit einem Anschluß­ stutzen versehenen Druckkasten, der in einem auf Unterdruck gehaltenen Decken- bzw. Wandhohlraum einsetzbar ist. Beide Varianten enthalten ein Schwebstoff-Filter (10), das über Spann- und Dichtungselemente (17/18 und 21) austauschbar ge­ gen den Druckraum (26) bzw. den Druckkasten festlegbar ist. Dabei sind mindestens zwei Dichtungsbereiche (13) und (15) zwi­ schen dem Rahmen (11) des Schwebstoff-Filters (10) und dem Druckraum (26) bzw. dem Druckkasten angeordnet, die zwischen sich einen Abstandsbereich eingrenzen, der lediglich in den Decken- bzw. Wandhohlraum (9) hinein offen ist. Dadurch wird bewirkt, daß bei auftretenden Lecks die Leckluft vom Rein­ raum weg in den Decken- bzw. Wandhohlraum (9) strömt. Durch die unterhalb des Rechteckrahmens (38) befestigten Gewebe­ bahnen (41) strömt die gefilterte Reinluft mit konstanter Strömungsgeschwindigkeit ohne das Aufwirbeln von Schweb­ stoffen in den Raum ein. Filter module for clean room ceilings and walls or the like, either from a pressure chamber (26) and this one stored ceiling or wall kept under negative pressure cavity (9) is formed or by one with a connection provided pressure box, which is in a vacuum held ceiling or wall cavity can be used. Both Variants contain a particulate filter (10) that over Clamping and sealing elements (17/18 and 21) interchangeable ge the pressure chamber (26) or the pressure box can be fixed. At least two sealing areas (13) and (15) are between rule the frame (11) of the particulate filter (10) and the Pressure chamber (26) or the pressure box arranged between limit a distance range that only in the Ceiling or wall cavity (9) is open. This will causes leaking air from the clean if leaks occur flows away into the ceiling or wall cavity (9). By the fabric attached below the rectangular frame (38) lanes (41), the filtered clean air flows at a constant rate Flow speed without whirling up levitation fabrics in the room.
