Parker Velcon 2" CDF Fuel Monitor Cartridges

The Parker Velcon CDF® P Series cartridges provide superior performance and reliability in standard fuel monitor housings through a unique, combination of media that absorbs water and filters solids that might be present in the fuel while helping reduce static charge build-up inside the vessel.

The injection molded endcaps bond with the media and with the O-ring seal on the outlet end. This minimizes the possibility of bypassing contaminated fuel or transmission of water downstream at low flow rates.

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

EI Specification 1583 6th Edition Information

Velcon's new CDF®-P Series Cartridges incorporate several structural features due to requirements of the Sixth Edition of EI 1583. Some of these include:

Increased product conductivity to decrease the risk of electrostatic discharges
Improved media structure to lower the risk of media migration
Lower initial DP - a major factor for installations that require changing cartridges at 15 PSID
New structure that provides longer cartridge life in the presence of small amounts of water

Some of the new requirements of the sixth edition of EI 1583 are:

18 lab qualification tests vs. 14 for the 4th edition
Testing salt resistance
Testing for cartridge conductivity
Testing for structural integrity
Testing for any trace SAP migration
Water slug test at low flow (10% of rated flow)
Low water (50 ppmv) at low flow (10% of rated flow)

Parker Velcon CDF® Fuel Monitor Cartridge Applications

Parker CDF® Fuel Monitor Cartridges are specifically designed for use in aviation fuel handling systems, where the highest levels of cleanliness and water removal are essential. These cartridges have historically been used in a range of point-of-use filtration applications to ensure fuel quality and safety prior to aircraft fueling.

Typical applications include:

Into-Plane Fueling – Final filtration before fuel is delivered to the aircraft
Fuel Hydrant Carts and Dispensers – Mobile fueling units at airports
Refueler Trucks – Onboard filtration systems for jet fuel delivery
Fixed Base Operations (FBOs) – Filtration at storage and dispensing points
Fuel Storage Facilities – Ensuring water and particulate removal from bulk storage tanks

While the CDF® series was widely used in these applications, it is important to note that due to changes in industry standards, they are being phased out and replaced with EI 1588-compliant alternatives, such as the Parker CDF-X™ Series, which provide enhanced safety and environmental compliance.

Parker CDF® Fuel Monitor Cartridge Q & A

+ What are Parker CDF® Fuel Monitor Cartridges, and how do they function?

Parker CDF® Fuel Monitor Cartridges are designed for aviation fuel filtration, combining water-absorbing media with particulate filtration. They utilize super absorbent polymer (SAP) technology to remove free and emulsified water from jet fuel, ensuring clean and dry fuel delivery. As water is absorbed, the cartridge swells, increasing differential pressure and signaling the need for replacement. Additionally, they filter out solid contaminants and reduce static charge buildup within the vessel.

+ Are CDF® Fuel Monitor Cartridges still approved for aviation fuel use?

No, CDF® Fuel Monitor Cartridges containing SAP are no longer certified for aviation fuel applications. The Energy Institute (EI) has phased out EI 1583-certified SAP-based monitors due to concerns over SAP migration into aircraft fuel systems. Operators are advised to transition to EI 1588-compliant alternatives, such as the Parker CDF-X™ Series, which utilize barrier technology to remove water without SAP.

+ What are the key features and specifications of CDF® Fuel Monitor Cartridges?

Micron Rating: 0.5 µm for particulate filtration.
Collapse Pressure: Exceeds 175 psi differential pressure.
Operating Temperature: Maximum of 160°F (71.1°C).
Water Holding Capacity: For example, the CDF-230P model holds approximately 120 ml of water.
Construction: Injection-molded end caps bonded to the media with an O-ring seal to prevent bypass.
Standards Compliance: Previously qualified to EI 1583 6th and 7th Edition specifications.

+ When should a CDF® Fuel Monitor Cartridge be replaced?

Replacement is recommended when the differential pressure across the cartridge reaches 25 psi (1.72 bar), indicating that the cartridge has absorbed its maximum water capacity or is clogged with particulates. Regular monitoring of differential pressure is essential to ensure optimal performance and prevent fuel flow restrictions.

+What is the recommended replacement for CDF® Fuel Monitor Cartridges?

The Parker CDF-X™ Series is the recommended replacement for CDF® Fuel Monitor Cartridges. These filters employ innovative barrier technology to repel water without using SAP, aligning with current EI 1588 standards. They are designed as drop-in replacements, compatible with existing 2-inch monitor housings, facilitating an easy transition without the need for equipment modifications.
