Abstract

PURPOSE:To make efficient the installation space and to change the ratio of a filter medium by connecting cartridges packed with the filter medium in parallel by connectors, simultaneously installing a pass closing part and connecting a cartridge packed with a different filter medium in a connector pass in series. CONSTITUTION:A filter consists mainly of active carbon cartridges 11, a hollow yarn cartridge 12 and upper and lower connectors 20, 30 by which the cartridges are connected in parallel from above and below. And fluid to be filtered is caused to flow in from a cap with an inflow port 26 to feed it to a pass 23 of the upper connector 20. At this time, since the pass 23 is closed by a pass closing plate 28, the fluid to be filtered is passed only through the active carbon cartridges 11 to flow in a pass 33 of the lower connector 30. And the primary fluid filtrate filtered by the active carbon is passed through a hollow yarn cartridge 12 and flows in the pass 23 of the upper connector 20 on the outflow port side of the pass closing plate 28. Then, the secondary fluid filtrate filtered by the hollow yarn flows out as it is from a cap with an outflow port 27.
