6 DESCRIPTION Model Number System. Refer to the box at right. The one or two digit Series Designator relates to the approximatemicron rating of eachmodel coalescer cartridge. Note that this is a nominal rating and should be used for reference only. The “0”, “2”, and “4” Series allfiberglass cartridges are rated at 25, 5, and 3microns respectively. The “2” and “4” Series are commonly used with diesel and other fuel oils, and are a compromise between filtration efficiency (cartridge life) and water removing capability. They coalesce gross water, but normally do not remove fine water haze. The all-fiberglass “6” Series was originally developed for jet fuel service (the original MIL-F-8901 specification). With a 2-micron rating, it has proven to be themost cost effective design in some jet fuel applications. “6” Series cartridges are also used in gasoline filtration service. However, it should be noted that the powerful detergent additives inmost automotive gasolines reduce the coalescing capability of this and other cartridge designs. “83” Series Cartridges. The 1-micron rated “83” Series is a pleatedmedia/fiberglass cartridge. The very practical “83” Series cartridges have become themost widely used design in applications including gasoline, condensate, and insulating oil filtration. “85” and “87” Series Cartridges. The “85” Series is rated at 0.5-micron while the “87” Series is rated at 0.3micron. Both incorporatemulti-layered pleated media. The “85” Series has consistently shown superior dirt holding capacity in the field. JF5 Series Coalescers. JF5 Series Cartridges are Parker Velcon’s newest design. Combined with V5N5 Series Separators, they offer higher flow rates and extended service life. EI*1581FifthEditionCartridges. I-6xxC5 (TB), I-6xxMM, and I-6xxA4 Series of coalescers incorporate a multi-layeredpleatedmediadesigned toprovide superior dirt holding capacity in the field, combinedwith 0.4micronefficiency. The I-6xxC5 (TB) replaces both the I-6xx85 (TB) and I-6xx87 (TB) cartridges. These cartridges are available in either threadedbaseor open-end configuration.

They are offered in lengths of 11”, 14”, 22”, 28”, 33”, 38”, 44”, and 56”. However, not all series are available in all lengths or in both end cap designs. 4” diameter cartridges are also offered for use with older equipment. They are available in a variety of lengths ranging from 8 to 40 inches. *EI (Energy Institute) is the new specification authority. API (American Petroleum Institute) is no longer involved in aviation fuel filtration specifications.
