  • Patent number: 5141638
    Abstract: A filtrating apparatus is disclosed in which a filter unit and a washing unit for effecting a fluid washing are unified into one system. A plurality of filter elements of main filters provided in the filter unit are made of sintered material containing metallic fiber. A nominal filtration rating of the filter elements is greater than 0.3 .mu.m but smaller than 2 .mu.m. Accordingly, it is possible to ensure the smooth filtration of beer funguses without any necessity of interchanging filter elements. It is therefore possible to reduce a running cost and filtration cost and to save a space for the apparatus.
