12 Inside-Out-Flow Filter FI Series - Specialized Filters for Use in Filter/Separator Vessels The Parker Velcon FI Series of Inside-to-Out flow filter cartridges are specially designed to replace the coalescer elements in filterseparator vessels. The FI filter cartridges are excellent choices to reduce filtration costs when flushing new systems, or when a filter/separator vessel is used to remove particulate matter only and not water. (Many surplus F/S vessels in the field have been used as pre-filter/micronic vessels.) The FG suffix, all fiberglass filter elements (e.g., Fl-644FG5), are intended for colloidal or slimy type matter; whereas the PL suffix, pleated paper filter elements (e.g., FI-644PLF5), are intended for normal particulate matter. 98% filtration efficiencywith micron ratings from 1/2 and higher Thermoset Adhesive Material – Durable endcap-tomedia bond prevents internal bypassing Buna-N Gaskets – The best general gasket material available, assures positive seals Coated Steel Components – Resist corrosion from most industrial fluids 75 psi Burst Strength– Heavy gauge carbon steel endcaps and outer reinforcing give safety margin against pressure surges APPLICATIONS All Hydrocarbon Fuels Glycols Water Emulsion Coolants Toluol Insulating Oils Synthetic Oils Cutting Oils Degreasing Fluids Naphtha Ethyl Alcohol Lube Oils Hydraulic Oils SPECIFICATIONS 75 psi Burst Strength 98% Nominal Filtration Efficiency 5 - 9 Operating pH range 160°F Maximum operating temperature Micron Ratings from 0.5 Inside-to-Out Flow Change out at 15 psid for Aviation applications FI-644PL1/2TB Please note: Cartridges may not look exactly like those shown in photo.
