Abstract

Cette invention concerne un filtre pour la filtration de liquides comprenant un boîtier de filtre monolithique comportant un orifice d'admission à une extrémité et un orifice d'évacuation à l'extrémité opposée. Le boîtier de filtre comporte un premier accouplement à fermeture autonome monté sur l'orifice d'admission et un second accouplement à fermeture autonome monté sur l'orifice d'évacuation. Les premier et second accouplements à fermeture autonome servent à raccorder des tuyaux souples pour le transport de liquides vers et depuis le filtre. Les accouplements comprennent chacun des première et seconde soupapes respectives qui sont conçues pour se fermer quand les premier et second accouplements sont désaccouplés. À l'intérieur du boîtier se trouve un milieu filtrant. Le boîtier de filtre et le milieu filtrant forment une unité scellée.
