Pleated filtration media, media packs, filter elements, and methods for filtering fluid are provided which contain three dimensional flutes in the media surface, the flutes configured to improve filter performance. In certain embodiments the flutes have defined peaks that reduce masking between adjacent pleats, the flutes have ridges along their length to modify flute cross sectional geometry, and/or the flutes provide for volume asymmetry across the media
Linvention concerne des matériaux de filtration plissés, des ensembles de matériaux, des éléments de filtration et des procédés de filtration dun fluide. Les matériaux selon linvention contiennent des cannelures tridimensionnelles sur la surface des matériaux, les cannelures étant configurées pour améliorer les performances de filtration. Selon certains modes de réalisation, les cannelures possèdent des pics définis qui réduisent le masquage entre des plis adjacents, les cannelures ont des crêtes le long de leur longueur pour modifier la géométrie transversale des cannelures et/ou les cannelures confèrent une asymétrie de volume aux matériaux.
