<p>A liquid filter (11) has a housing (13) with a bottom and a top (17). A vertical partition (27) divides the housing into an inlet chamber (29) on one side and outlet chamber (43) on the other side. One type of filtration material is located in the inlet chamber. Another type is located in the outlet chamber. The inlet to the inlet chamber is located in the bottom of the housing and results in an upward flow through the inlet chamber. The outlet chamber has an outlet located in the bottom. A port (41) locates at the top of the partition. This results in a downward flow through the outlet chamber.</p> |
