Abstract:
A water separator and particulate filter with a first or outer stage configured to coalesce water from fluid such as fuel, and a second or inner stage configured to separate coalesced water from the fluid and also remove fine solid contaminants from the fluid. The coalescing stage includes a pleated cylinder of polymeric media. The pleated cylinder has pleat valleys and downstream pleat tips, and release sites defined at the downstream pleat tips. The separator stage includes a non-pleated cylinder of polymeric media surrounding and in contact with outer pleat tips of a multi-layer pleated cylinder.
