MULTI-SECTION POROUS LIQUID FILTER WITH NON-MECHANICAL GAS VENT

摘要

Embodiments of the present invention provide filters and method for their use that introduce two sections, one filtration section and one venting section, in a single filter. The filtration section allows water to penetrate, and the venting section does not allow water to penetrate, but does allow air to penetrate. Because the venting section does not allow water to penetrate, the air will not need to overcome the bubble point pressure to move through the venting section. The venting section also provides a low pressure air pathway for the air but not water.
