Title (EN) LAYERED FILTER STRUCTURE COMPRISING SHORT METAL FIBERS
(FR) STRUCTURE DE FILTRE EN COUCHES A FIBRES METALLIQUES COURTES
Abstract: front page image
(EN)The invention relates to a layered filter structure, said filter element comprises - a first layer, said first layer comprising a porous metal layer; - a second layer, said second layer comprising a self-supporting layer of sintered short metal fibers. The first and the second layer are sintered together. The layered filter structure is in particular suitable as surface filtration medium, for example for the filtration of liquids or gases.
(FR)L'invention concerne une structure de filtre en couches, qui comprend: une première couche renfermant une couche métallique poreuse; une seconde couche renfermant une couche autoportante de fibres métalliques courtes frittées. Ces première et seconde couches sont réunies par frittage. Ladite structure est particulièrement indiquée comme moyen de filtration superficielle, par exemple pour la filtration de liquides ou de gaz.
