FILTERINDRETNING, OG FILTERAPPARAT AF SAADANNE FILTERINDRETNINGER

摘要

A filter device for filtering out particles from an aeriform, flowing medium has a substrate 22 and a filter coating applied to the substrate 22. The filter coating is a filter liquid 36 that wets the substrate 22. At least one such filter device 20 is fitted in a housing 12 in order to form a filter apparatus 10. The housing 12 has an inlet opening 14 and an outlet opening 16 for the medium to be filtered. In order to obtain effective wetting of the air-permeable substrate 22 of at least one filter device 20 of the filter apparatus 10, an irrigation unit 44, which is flow-connected to the filter devices 20 and flow-connected to a collecting chamber 38 for the filter liquid, is fitted in the housing 12. A pump 47 serves for circulation of the filter liquid 36 between the collecting chamber 38 and the irrigation device 44. <IMAGE>
