ABSTRACT:
A filter apparatus including a plurality of demountable filter cartridges which each include a replacement filter element. The cartridges are mounted in the upper portion of a bi-level partition that extends across a tank having an inlet below the partition and an outlet above the lower portion of the partition at a height to be bisected by the upper surface of the upper portion of the partition. A plurality of filter apertures through the partition each receive a cartridge and each cartridge is held in place via studs that screw into the partition and received in channels formed in a header portion of the cartridge so that the cartridge can be inserted into an aperture and turned to engage the shanks of the studs with the channels in the cartridge header. The headers of the cartridges are constructed in two parts and connected by a tubular connector having threads of opposite senses on its periphery and in its bore to be screwed into one part of the header and over a threaded projection on the other part of the header to clamp the two pieces of the header together about an O-ring that seals the cartridge to the aperture wall.
