Title
(EN) FILTER ELEMENT HAVING SEALING MEMBERS AND METHODS
(FR) ENSEMBLE FILTRE COMPORTANT DES ELEMENTS D'ETANCHEITE ET PROCEDES ASSOCIES
Abstract
(EN) A filter arrangement includes a media construction comprising a corrugated sheet secured to a flat sheet rolled into a coiled construction. A frame and a first seal member are provided. The frame secures the first seal member to the coiled construction. The first seal member is preferably oriented to form a radial seal with a housing. A second seal member is secured to the outer annular surface of the coiled construction. The second seal member includes a gasket extension having first and second opposite ends; an attachment portion; and a protrusion extending from the attachment portion. The second seal member is preferably oriented to form an axial seal with a housing. Air cleaners preferably utilizing filter arrangements as described herein operably installed within housings. Methods of installing, filtering, assembling, and servicing preferably include arrangements as described herein.
(FR) L'invention concerne un ensemble filtre qui comprend un moyen de filtration comportant une feuille ondulée fixée à une feuille plane enroulée de manière à former une structure en spirale. Cet ensemble comprend un châssis et un premier élément d'étanchéité. Le châssis fixe le premier élément d'étanchéité à la structure en spirale. Le premier élément d'étanchéité est de préférence orienté de façon à former un joint d'étanchéité radial avec un logement. Un second élément d'étanchéité est fixé à la surface annulaire extérieure de la structure en spirale. Le second élément d'étanchéité comprend un prolongement de joint comportant une première et une seconde extrémité opposées; une partie de fixation; et une partie saillante s'étendant de la partie de fixation. Le second élément d'étanchéité est de préférence orienté de façon à former un joint d'étanchéité avec un logement. L'invention concerne également des filtres à air qui utilisent des ensembles filtre comme celui décrit ici, installés de manière fonctionnelle à l'intérieur d'un logement. L'invention concerne en outre des procédés d'installation, de filtration, d'assemblage, et d'entretien faisant appel de préférence aux ensembles faisant l'objet de cette invention.
