발명의 명칭: (EN) PLEATED FILTER ELEMENT COMPRISING PLEATED FILTER MEDIA WITH EDGE DAMS, AND METHOD OF MAKING AND USING
(FR) ÉLÉMENT DE FILTRE PLISSÉ COMPRENANT DES MILIEUX FILTRANTS PLISSÉS AVEC DES BARRAGES DE BORD, ET PROCÉDÉ DE FABRICATION ET D'UTILISATION
요약서:
(EN) A pleated filter element comprising a pleated filter media comprising a plurality of oppositely-facing pleats with a pleat direction and with a plurality of upstream and downstream pleat tips and pleat valleys, wherein the pleated filter media comprises two corrugated edges and two noncorrugated edges. The first (second) corrugated edge of the pleated filter media comprises an edge dam of hardened adhesive that occupies the upstream and downstream pleat valleys at a location laterally inwardly proximate the first (second) corrugated edge and that extends along an entire longitudinal extent of the pleated filter media. The pleated filter media is a multilayer media comprising an organic polymeric nonwoven web, that exhibits a Percent Penetration of less than 5, laminated with a fiberglass prefilter layer that is disposed upstream of the primary filtration layer and that exhibits a Percent Penetration of greater than about 70.
(FR) Un élément de filtre plissé comprend un milieu filtrant plissé comprenant une pluralité de plis à l'opposé l'un de l'autre ayant une direction de pli et avec une pluralité de pointes de pli amont et aval et de vallées de pli, le milieu filtrant plissé comprenant deux bords ondulés et deux bords non ondulés. Le premier (second) bord ondulé du support de filtre plissé comprend un barrage de bord d'adhésif durci qui occupe les creux de pli amont et aval à un emplacement latéralement vers l'intérieur à proximité du premier (second) bord ondulé et qui s'étend le long d'une étendue longitudinale entière du milieu filtrant plissé. Le milieu filtrant plissé est un milieu multicouche comprenant une bande de non-tissé polymère organique, qui présente un taux de pénétration inférieure à 5, stratifié avec une couche de préfiltre en fibre de verre qui est disposée en amont de la couche de filtration primaire et qui présente un taux de pénétration supérieure à environ 70.
