FLUID-FILTERING FILTER ELEMENT USING FOLDING FILTER MEDIUM

PROBLEM TO BE SOLVED: To provide stability and desirable fluid characteristics of air streams by reducing cost in a fluid-filtering filter element.SOLUTION: This invention relates to a filter element 20 for filtering a fluid 18, in particular, air and has a filter element using a folding filter medium 26 where a folding edge 32 of a folding part 28 defines a filter element inflow surface 40 on the unprocessed side, and filter element outflow surface 42 on the clean side. The filter element 20 has at least one filter medium stabilization element 48, and the filter medium stabilization element 48 has a stabilization part 50 having an outer shape 51 adapted to the outer shape 53 of the filter medium 26. The stabilization part 50 is positioned on contact with the filter medium 26 to stabilize the filter medium 26. The filter medium stabilization element 48 is positioned on the opposite side of the stabilization part 50 to project from the inflow surface 40 on the unprocessed side and from the outflow surface 42 on the clean side. Further, this invention relates to a filter using the filter element 20.SELECTED DRAWING: Figure 3 【課題】流体濾過用フィルタエレメントにおいて、コストを低減し且つ安定性及び好ましい気流の流動特性を得られるようにする。【解決手段】本発明は、流体１８、特に空気を濾過するフィルタエレメント２０に関し、折り畳み部２８の折り畳みエッジ３２が未処理側でフィルタエレメントの流入面４０を、清浄側でその流出面４２を定義された折り畳み濾材２６を用いたフィルタエレメントを有する。フィルタエレメント２０は少なくとも１つの濾材安定化エレメント４８を有し、濾材安定化エレメント４８は、濾材２６の外形５３に適合する外形５１を持つ安定化部５０を有し、安定化部５０は濾材２６を安定させるべく濾材２６と接して位置し、濾材安定化エレメント４８は、安定化部５０の反対側に位置し、未処理側で流入面４０から突き出し、清浄側で流出面４２から突き出す。また、本発明は当該フィルタエレメント２０を用いたフィルタに関する。【選択図】図３
