Parker Velcon CO-718 Clay Canister Cartridges

The Parker Velcon CO-718 Series cartridges are intended for use in all clay treatment vessels designed for nominal 7” x 18” cartridges. The treatment/purification medium is a special blend of Low Volatile Materials (LVM) fuller’s earth compounded to provide the optimum balance between adsorptive capacity and water resistance. With their ability to prevent channeling and their high particle structure stability, the cartridges assure reliable performance and long life in the most exacting process applications.

Jet Fuel Treatment

One of the most common uses for clay cartridges is to remove surfactants from jet fuels. Surfactants can carry over from the refinery process or be picked up when the jet fuel travels through multi-product pipelines (corrosion inhibitors, gasoline additives, etc.). Surfactants will eventually disarm filter/separators, which are primarily designed to remove water from the jet fuel. By removing surfactants from the fuel, the clay cartridges protect the downstream filter/separators. Since clay removes the surfactants by an adsorbent (adhering) action, the fuel residence time, or time in contact with the clay, is very important for proper fuel treatment. Normally, a flow rate of about 6.5 gpm per 7” x 18” cartridge is ideal for jet fuel.


CO-718CE is a rugged canister cartridge featuring aluminized steel endcaps and center-tube, polyester felt outerwrap and both interior and exterior media migration barriers. A wire bail provides for easy installation and removal. Buna-N gaskets at each end assure tight sealing. The improved construction offers high resistance to transit or handling damage and to differential pressures up to 100 psi.
