Patent ID: 8075775

Claim:
A replaceable filter leaf apparatus for use in an associated filter system including a housing having a cavity with fluid inlet and outlet ports for conducting a flow of fluids into and out from the housing and having a manifold operatively coupled with the outlet port, the filter leaf apparatus comprising: a drainage grid member defining a plane and comprising at least one channel for directing a fluid to flow in one or more directions substantially parallel with the plane defined by the drainage grid member; a porous filter media disposed adjacent the drainage grid member for filtering the fluid entering the grid member; and, a nozzle adapter member operatively coupled with the drainage grid member and the porous filter media, the nozzle adapter member defining an elongate passageway for conducting fluids therethrough along a first direction within the nozzle adapter member, the nozzle adapter member adapting the filter leaf apparatus for selective slidable connection with the manifold of the associated filter system in a second direction substantially perpendicular to the first direction, wherein a sealing portion of the nozzle adapter member is configured to generate a seal in a sealing plane between a margin surface surrounding an outlet of the elongate passageway of the nozzle adapter member and the associated manifold by biasing the nozzle adapter member against the associated manifold along an axis substantially perpendicular to the sealing plane.
