sub-drain block for a filtration system, retainer for a filtration medium and filter system

摘要

The present invention relates to a filtration system having a filter media sealing retainer including: at least one sub-drainage block for a filtering system, filter media retainer and filter system having an upper wall, a lower wall and a pair of side walls extending between the upper wall and the lower wall; a retainer for a filter means mounted over the upper wall of the at least one sub-drainage block; and at least one rib positioned between the sub-drainage block and retainer for a filtering means. at least one rib forms a seal between the sub-drainage block and retainer for a filter means and prevents the filtering medium from entering the sub-drainage block. at least one rib may be monolithically formed in at least one sub-drainage block. alternatively, the at least one rib is monolithically formed in the retainer for a filtering means. the rib is deformable and bites a surface over the assembled part to reduce or eliminate the need for a separate seal. ?? ?? ?? ?? 1/1
