Abstract:
A recharge and filter cartridge, comprising:a ring of filter media having a first end, a second end, and circumscribing a central cavity, a cylindrical weir inwardly bounding and extending along at least a portion of the length of the media, and a flow passage along the length of the media allowing fluid flow between the media and the central cavity internally of the weir; a first end cap fixed to the first end of the media ring and a second end cap fixed to the second end of the media ring; and a recharge canister supported in the central cavity of the ring of filter media between said first and second end caps, and a flow path between the recharge canister and the weir, a first seal for sealing the recharge canister around its periphery to the weir at an axial location along the canister such that fluid passing radially through the filter ring and through the flow passage is directed against one end of the recharge canister, the recharge canister including a flow opening through an annular sidewall of the canister to allow fluid to pass from the one end of the recharge canister into the flow path between the recharge canister body and the weir, the flow path extending to an outlet opening in the second end cap.
