Abstract

A filter arrangement for use with a vessel that receives fluid includes a body engageable with the vessel. The body has an inlet port, an outlet port, a body cavity, a first fluid path disposed between the inlet port and body cavity, and a second fluid path disposed between the body cavity and the outlet port. A filter is disposed at least partially in the body cavity, and includes a filter cavity and filter media for filtering the fluid. A valve is associated with the body for allowing the fluid to flow into and out of the vessel. When the fluid flows into the vessel, the fluid flows through the filter cavity and along the first fluid path without flowing through the filter media. When the fluid flows out of the vessel, the fluid flows along the first fluid path, through the filter media and along the second fluid path.
