Patent ID: 8883003

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 comprising two bearing surfaces arranged on respective opposite sides of said manifold; two clamping plates each facing a respective bearing surface, through which bearing surfaces 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 surfaces; at least one guiding rod which extends between said manifold and said clamping plates and at least one actuator, 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 plates have a starting position in which said plates are away from said set of at least one filter cassette and a clamped position in which said plates are 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 plates are configured such that said actuator drives said clamping plates via said guiding rod to their 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; and wherein said body of said actuator is movably mounted in a sleeve fixed to said manifold.
