Title
(EN) PLEATED MEDIA FOR A CONICAL SHAPED FILTER ELEMENT
(FR) SUPPORT PLISSÉ POUR ÉLÉMENT FILTRANT DE FORME CONIQUE
Abstract
(EN)
A frusto-conical filter includes at least one layer of a filtering material, wherein one or more layers of the at least one layer of a filtering material comprises a plurality of pleats. Each of the pleats has a center axis which essentially maintains a constant distance from the center axis of its adjoining pleats. The media filter has a first end and a second end, the second end being spaced apart from the first end, and one of the first and second ends is larger than the other of the first and second ends. A method of making this media involves cutting out a frusto-conical section from a generically shaped media and aligning it in such a way as to maintain the constant distance of the pleats from the adjacent pleats.
(FR)
Un filtre tronconique comprend au moins une couche d'un matériau filtrant, une ou plusieurs couches de la ou des couches d'un matériau filtrant comprenant une pluralité de plis. Chacun des plis a un axe central qui maintient sensiblement une distance constante à partir de l'axe central de ses plis adjacents. Le filtre à support a une première extrémité et une seconde extrémité, la seconde extrémité étant espacée de la première extrémité, et l'une des première et seconde extrémités étant plus grande que l'autre des première et seconde extrémités. Un procédé de fabrication de ce support consiste à découper une section tronconique à partir d'un support de forme générique et à l'aligner de manière à maintenir la distance constante des plis à partir des plis adjacents.
