The FW filter cartridges work by chemically locking water into the media and holding it in suspension, preventing downstream contamination, even when surfactants or water dispersing fuel additives are mixed in. The FW filter cartridges will remove water down to less that 5 ppm, with each filter cartridge holding up to four litres of water and up to 196 grams of solids.
Parker Racor FW cartridges are compatible with industry standard filter vessels sized for 5 x 12, 6 x 14, 7 x 18 and 8 x 22 cartridges, and are interchangeable with many industry replacement elements.
