• Recommended change out pressure: 25 psid (1.7 bar)
• Water absorbance and particulate retention will increase differential pressure to the change out pressure
• Buna-N sealing materials are standard
• Maximum operating temperature 150°F (65°C)
• All AD products will remove free and emulsified water from both diesel and biodiesel fuels to levels below 50ppm
• The water absorbing technology used in AD filters is not effective in the presence of fuels containing high concentrations of alcohol
  
  
  DI & DSO Series
  Particulate and Water Removal from Diesel Fuel
  
  Features
• All filter components are compatible with petroleum based diesel fuels
• Downstream free-water level typically below 50ppm
• Recommended change out pressure: 25 psid (1.7 bar)
• Buna-N sealing materials are standard
• Maximum operating temperature 150°F (65°C)
• 6" (15.2 cm) outer diameter
• DI - coalesce flow direction - inside to outside
• DSO - separator flow direction - outside to inside
• Water coalescing is not effective in the presence of fuels containing high levels of surfactants/alcohols or unrefined biofuels
• Detergents and additives inhibits the ability of coalescers to effectively remove water by reducing Interfacial Tension and can eventually disarm coalescers

CO-718 Series Cartridges for Fuel and Oil Treatment

The Velcon CO-718 Series elements 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 elements assure reliable performance and long life in the most exacting process applications.

For further information on clay and how to deterrmine when the clay elements should be changed see data sheets.

Field Proven: CDF Replacement Cartridges Assure Clean Dry Fuel Delivery

The Velcon CDF^® P Series cartridges are designed to provide superior performance and reliability in standard fuel monitor housings through a unique, patented combination of media that absorbs water, filters solids that may be present in the fuel, and provides for reduced static charge.

The cartridge has injection molded endcaps that are bonded to the media and an O-ring seal on the outlet end. This minimizes the possibilities of bypassing contaminated fuel or transmission of water downstream at low flow rates.

As the cartridge removes water and/or dirt from the influent fuel there will be an increase in the pressure differential along with a decrease in flow rate. These changes are the result of flow restriction caused by dirt filtration or water absorption in the media. The rate of these changes depends on the quantity of water or dirt contaminants present.

• CDF-P Series are qualified to IP 1583 6th Edition, a specification for Aviation Fuel Filter Monitors.
• Improved Salt Water Performance.
• Conductive End Caps and adhesive for reduction of static charge within the vessel.
• O-Ring Seal minimizes the possibility of bypassing contaminated fuel at differential pressures up to 175 psi.
• Rugged Construction, collapse strength exceeds 175 psi differential pressure.

Caution
Do not use with pre-mixed fuel containing anti-icing additives.

Removes Water and Dirt from Jet Fuel and Avgas Outside-to-In Flow Cartridges

Patented (US Patent no. 4,242,206) Aquacon Filter Cartridges have a unique high-capacity inner filter media which removes all free and emulsified water from hydrocarbon fuels down to less than 5 ppm in the effluent. Absorbed water is chemically locked into this media.

When a cartridge reaches its water holding capacity, its accordion pleats swell and cause an increase in the differential pressure which signals the operator to change the cartridge.

Solid contaminants are removed by the cartridge’s two particulate filter media layers. The pleated accordion style design provides a large surface area for maximum dir t holding capacity. Models are offered for particulate filtration down to 1/2 micrometer size with 98% plus efficiency. Performance is not affected by the presence of common surface active agents.

Compact Aquacon Cartridges are quick and easy to install. Models are available to fit most existing standard housings.

• Free and emulsified water to less than 5 ppm
• 1/2 micrometer particulate removal
• Provides protection against “slugs” of water
• Pressure increase signals cartridge change
• Use with existing filter housings

1/2 micron rated Aquacon Cartridges are recommended for use with jet fuel and avgas. Effluent quality meets requirements for IP-1583 6th Edition.

Caution
Do not use with pre-mixed fuels containing anti-icing additives.

Use form for cartridge changeout at flowrates less than rated flow.

Filter/Separator 2nd Stage Elements.

Separator Cartridges are employed as the second stage in filter/ separator vessels. Their sole function is to repel coalesced water drops produced by the first stage cartridges while allowing hydrocarbon fluids to pass through. Water drops settle into the filter/ separator sump and are not carried downstream. All particle filtering is done by the first stage coalescer cartridge.

• Optimum 2nd stage water removal.
• Choice of Teflon^® Coated Screen, Synthetic or Pleated Paper Media.
• Field proven performance.
• Largest selection of replacement elements.
• TCS medium is 200 mesh stainless steel screen coated on both sides with green Teflon. The screen is lockseam folded and fastened with an internal aluminum clip.
• End caps and tubes are aluminum.
• Gaskets are Buna-N.
• Pleated medium is silicone treated resin impregnated paper with a protective outer aluminum screen jacket.
• pH range is 5 to 9.
• Maximum operating temperature is 200°F.
