Abstract
A filter apparatus has a housing, an inlet port on one side of the housing and an outlet port on an opposed side of the housing. Sheet media is disposed in the housing having a first opening through the sheet media. Also dispersed in the housing is a bag media comprising an enclosed bag with a second opening into the bag. The first opening and the second opening are connected in fluid communication with each other and the sheet media is disposed before the bag media in the direction of flow through the housing so that both media are mounted inside the housing. Some fluid entering the inlet passes through both openings and through the bag media and into the outlet, and other fluid entering the inlet passes through the sheet media and then to the outlet.
