Title (EN) POLYGONAL FILTER ELEMENT WITH RADIUSED CORNERS
(FR) ELEMENT FILTRANT POLYGONAL A COINS ARRONDIS
Abstract: front page image
(EN)A filter element for removing contaminant from a dirty stream, such as an air filter element for removing and/or coalescing liquid contaminant from an incoming dirty air stream. The filter element has a polygonal shape, with radiused corners. Such a shape mitigates pleat bunching, reduces airflow resistance, thus increasing in the volume of incoming air when compared to conventional cylindrical filter elements having the same surface area and pleat heights. Examples of polygonal shapes include rectangular (including square) and triangular. The filter element may be tapered.
(FR)L'invention concerne un élément filtrant destiné à éliminer un contaminant d'un flux pollué, comme un élément de filtre à air destiné à éliminer et / ou à coalescer un contaminant liquide issu d'un flux d'air pollué entrant. L'élément filtrant présente une forme polygonale à coins arrondis. Une telle forme atténue le tassement des plis, réduit la résistance au flux d'air, augmentant ainsi le volume d'air entrant par comparaison aux éléments filtrants cylindriques conventionnels de même aire surfacique et de même hauteur de plis. Parmi les formes polygonales, on peut citer les formes rectangulaire (notamment carrée) et triangulaire. L'élément filtrant peut être effilé.
