Die auf dem Filter abgeschiedenen Bakterien werden durch die UV-Bestrahlung abgetötet. Die Schwebstoffilter können während ihrer vollen sogenannten Standzeit in der Filteranlage verbleiben, wobei unter "Standzeit" eines Schwebstoffilters die Zeit verstanden wird, während der der Widerstand des Schwebstoffilters gegen den Luftdurchgang unter einem bestimmten Grenzwert bleibt. Aufgrund der zunehmenden Abscheidung von Staubteilchen nimmt der Luftwiderstand des Schwebstoffilters mit der Zeit zu. Die Standzeit der Schwebstoffilter gemäß dem Hauptpatent ist somit nur durch die zunehmende Verschmutzung des Filters und den dadurch ansteigenden Luftwiderstand bedingt. Nach dem Hauptpatent können für die Belüftung beispielsweise von Kranken häusern und sterilen Räumen Schwebstoffilter mit der gleichen Standzeit benutzt werden, wie es in der Technik allge mein üblich ist.The bacteria deposited on the filter are carried through the UV radiation killed. The particulate filters can remain in the filter system during their full so-called service life, with the "service life" of a particulate filter the time is understood during which the resistance of the particulate filter to the passage of air is below remains a certain limit. Due to the increasing deposition of dust particles, the air resistance increases of the particulate filter increases over time. The service life of the particulate filter according to the main patent is therefore only due to the increasing contamination of the filter and the resulting increase in air resistance. According to the main patent can be used for the ventilation of hospitals and sterile rooms, for example, with the same filter for particulate matter Stand time can be used, as it is my common practice in technology.
Gemäß einer weiteren Ausbildung nach dem Hauptpatent kann das Schwebstoffiltermaterial aus hydrophobem Glasfaserpapier bestehen.According to a further embodiment according to the main patent, the suspended matter filter material can be made of hydrophobic glass fiber paper exist.
