Description The PetroClear® model 40510D utilizes a 10 micron (nominal) cellulose media to remove particulate from gasolines plus water sensing in neat gasoline and phase separation detecting capabilities for Ethanol blended gasoline. Removes particulate 10 microns (nominal) or larger. It utilizes a super absorbent media for sensing water in neat gasoline and a chemical core assembly to detect and react to phase separation in Ethanol blended fuel. Once the PetroClear® model 40510D has absorbed 5.9 ounces (175 mil) of water from neat gasoline, flow will be noticeably slow. The chemical center core assembly detects and reacts to phase separation and significantly restricts flow through filters.
