Title (EN) FILTERING
(FR) FILTRAGE
Abstract:
(EN) filter unit (22) for fitting in a filter housing (12, 14), said filter unit comprising a plurality of elements (34, 36, 38, 40) including at least one filter element (34, 36) and one hydrophobic element (38) and scrim means (42, 44) substantially enclosing said elements, opposed edge regions of said scrim means being joined together such that said elements are maintained in a predetermined juxtaposed relationship by said scrim means. The assembly of the elements into a filter unit with the elements maintained in the desired relationship by the scrim means facilitates the assembly of filter apparatus incorporating those elements.
(FR) La présente invention concerne une unité de filtre (22) se montant dans un logement pour filtre (12, 14). Cette unité de filtre est constituée de plusieurs éléments (34, 36, 38, 40) comprenant au moins un élément de filtre (34, 36) et un élément hydrophobe (38) ainsi qu'un organe en non-tissé (42, 44) contenant les éléments de filtre. Les bordures opposées de l'organe en non-tissé se rejoignent de façon à maintenir les éléments de filtre dans une relation de juxtaposition prédéfinie, sous l'effet de l'organe en non-tissé. Lorsque ces éléments sont montés dans l'unité de filtre, le maintien par l'organe en non-tissé des éléments de filtre dans la relation voulue, facilite le montage de l'appareil filtrant intégrant ces éléments.
