Patent attributes
Filter cartridges and manifold blocks for filter manifold systems are described. The filter cartridges include flanges surrounding openings at first and second ends of the filter cartridge, with face seals in the flanges. Manifold blocks include end blocks, at least one of which is movable so that the distance between the end blocks can be changed. When a filter cartridge is installed into the manifold by engagement of the flanges with slots in the manifold end blocks, a fluid pathway is formed through a first manifold end block, into the filter cartridge, through the filter cartridge, out of the filter cartridge and into a second manifold end block. The fluid pathway is sealed by the face seals where the flow is from a manifold end block into or out of the filter cartridge.
