Abstract

La présente invention concerne un filtre constitué d'éléments filtrants (33) dotés de brides terminales (35,36) reliées ensemble de manière étanche. Le joint étanche peut être maintenu au moyen d'une tige (56) disposée dans le sens de la longueur et traversant des ouvertures (55) dans les brides terminales, l'une des extrémités de cette tige assurant de manière réversible la fixation des éléments filtrants, l'autre extrémité étant fixée au boîtier. Les éléments filtrants peuvent être logés dans une enveloppe (101) et une vis de pression (107) située dans l'enveloppe peut servir à appliquer une force sur lesdits éléments filtrants pour maintenir l'étanchéité des joints. Le filtre peut être équipé d'un épurateur (80) capable d'aspirer la matière déposée sur le filtre.
