IMPROVED COMPOSITE FILTER ELEMENT

摘要

A combination filter element comprising a bundle of hollow microporous fibers (48) housed within an extruded carbon block (44), wherein the carbon block is fabricated to balance particle retention capacity against absorption capacity to provide a composite filter with desirable pressure drop, filter life, and particulate and chemical contamination reduction, and a filtration device, in which the combination filter element may be employed, having a base portion (14) including a sump (32) which has an inlet (28) and an outlet (30) for receiving the filter element.
