PROBLEM TO BE SOLVED: To reduce maintenance cost by prolonging a life of a filter element provided in a filter apparatus thereby reducing replacement frequency.SOLUTION: A lot of long and bottomed cylindrical filter elements 22 are spaced in parallel in a housing, the cylindrical filter element 22 is supported on a partition plate 18 at an upper part, and positioned to a positioning plate 26 at a lower part. A spacer plate 30 is horizontally set at an intermediate portion of the cylindrical filter element 22. Semicircular concave parts 34 are formed in an engraved manner in an outer peripheral edge 30a of the spacer plate 30, and round holes 32 are drilled at inside portions. An interval I allowing the cylindrical filter elements 22 to be arranged therein is provided between the outer peripheral edge 30a of the cylindrical filter elements 22 and a body inner face 12a. |
