Patent ID: 8877052

Claim:
A device for filtration with a set of least one filter cassette comprising: a manifold providing fluid connection and mechanical connection comprising at least one flow inlet for a fluid to treat, at least one flow outlet for a treated fluid and a network for conveying said fluid to treat and said treated fluid, said manifold having a bearing surface for a said filter cassette, through which bearing surface emerge cassette feed ports and cassette return ports communicating with said conveying network, which cassette feed ports and cassette return ports are configured to communicate with conduits formed in a said filter cassette bearing against said bearing surface; a clamping plate; and at least one guiding rod which extends between said manifold and said clamping plate and at least one actuator, for driving and guiding said clamping plate parallel to and facing said bearing surface, which is provided with a body and a member moveable relative to said body, which moveable member has an extended position and a retracted position in which said moveable member has been moved through a predetermined travel relative to its extended position, by virtue of which the clamping plate has a starting position in which said clamping plate is away from said set of at least one filter cassette and a clamped position in which said clamping plate is approached and compresses said set of at least one filter cassette against said manifold; wherein said body is carried by said manifold; said moveable member carries said guiding rod; and said actuator, said guiding rod and said clamping plate are configured such that said actuator drives said clamping plate via said guiding rod to its clamped position in which said moveable member is in an intermediate retracted position in which said moveable member has moved through a shorter travel than said predetermined travel relative to its extended position; said device further comprising at least one holding and guiding rod for holding and guiding said set of at least one filter cassette which is carried by said manifold and which extends through at least one aperture formed in said clamping plate; and wherein said body of said actuator is movably mounted in a sleeve fixed to said manifold.
