HFS-251 Filter Separator Series

The single stage filter separator is a system designed and manufactured for the most rapid and efficient removal of water and solids from fuels, light oils, and solvents. Basic design includes 150# carbon steel construction, liquid level gauge, pressure gauges on inlet and outlet and manual vent/drain valves.

Single stage filter separators are ideal for lower flow applications where a coalescing element with a surrounding outer sock or our Teflon™ coated screen that provides separation is used.

HFS-251 vessels are compact, light weight and able to handle flow rates up to 150 GPM. These low profile vessels are ideal for mobile and marine applications where equipment has to be moved often and available working space is limited.
