Abstract
A filter assembly and cage and/or capsule apparatus including upstream and downstream and optional intermediary supports having modified features to maximize fluid flow through the filter assembly. The cage apparatus has a plurality of posts with stacked ridges that function as cap engaging teeth. A cage end cap is formed with a plurality of slots corresponding in configuration and position to the plurality of posts. The combination of slots and ridges interact to create a locking mechanism to adjustably secure the end cap to the cage and to generate the necessary compression to seal the enclosed filter discs and supports. The upstream supports are formed with channels in an outer ring and optional channels in radially extending ribs to improve fluid ingress and transfer to the filter discs. The downstream supports are formed with channels or tunnels in an inner ring to facilitate filtrate egress into a filter assembly outlet.
