Filter Cartridge FO-644A3TB

Coalescer cartridges are employed as the first stage in filter/separator vessels for hydrocarbon fluids. They perform two functions: (1) coalesce (combine) highly dispersed, emulsified water particles into larger water drops and (2) filter-out particulate contaminants.

Product Features:

• Cost effective particle and emulsified water removal from hydrocarbon fluids
• Easy installation and replacement with one-piece design
• Choice of Threaded Base or Open End cartridges
• Choice of All-Fiberglass Media or Combination Fiberglass and Pleated Media
• Field proven performance
• Ongoing qualification testing to meet changing commercial and military requirements
• Used as a first-stage cartridge in Filter/Separatos
• Remove particulates and coalesce water into large water drops
• Also available in screw base design

Model Number System. Refer to the box at right. The one or two digit Series Designator relates to the approx­imate micron rating of each model coalescer cartridge. Note that this is a nominal rating and should be used for?reference only.

The “0”, “2”, and “4” Series all-fiberglass cartridges are rated at 25, 5, and 3 microns 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 the most 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 in most automotive gasolines reduce the coalescing capability of this and other cartridge designs.
“83” Series Cartridges. The 1-micron rated “83” Series is?a pleated media/fiberglass cartridge. The very practical “83” Series cartridges have become the most 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 0.3 micron. Both incorporate multi-layered pleated media. The “85” Series has consistently shown superior dirt holding capacity in the field.

JF5 Series Coalescers. JF5 Series Cartridges are Velcon's newest design. Combined with V5N5 Series Separators, they offer higher flow rates and extended service life. See data sheet #1923 for more info.
