Description The PetroClear® model 40530A utilizes a 30 micron (nominal) cellulose media to remove particulate from Ethanol blended gasoline. Removes particulate 30 microns (nominal) or larger. The “Alert” models 40510A and 40530A are designed to detect and react to phase separation in Ethanol blended gasoline. The maximum flow rate for PetroClear® models 40510A and 40530A is 25 gpm (94.6 lpm). Maximum operating pressure is 50 psid (3.4 bar). Collapse pressure is 150 psid (10.3 bar). Maximum operating temperature is 250°F (139°C). The chemical center core assembly detects and reacts to phase separation and significantly restricts flow through filters.
