All the updates on JIG's work to phase out SAP-based Filter Monitor technology from jet-fuel handling applications. Starting with Bulletin 105 to the latest Field Trial updates.
A Joint Industry Field Trial programme was started by JIG in cooperation with IATA and A4A to conduct operational trials on new filtration technology developed by the manufacturers and qualified to a relevant EI (Energy Institute) Specification. The Field Trials have been running since July 2019 and have so far resulted in the adoption of Electronic Water Sensor and Dirt Defence filter combinations for into-plane use. (Bulletin 130). Further details on new technologies being field trialled or in development can be found below.

LATEST FIELD TRIAL INFORMATION (May 2022)
PARKER WATER BARRIER FILTER
As indicated in Technical Newsletters, the Joint Industry Field Trial Group have been working with Parker-Velcon to better understand and correct some potential structural weaknesses in the elements that can in certain conditions reduce their level of performance.
Following some recent testing, the manufacturer has decided to redesign the open end cap to improve performance and reliability. Such a redesign requires at least a partial requalification to the EI1588 Specification. JIG has indicated in Bulletin 143 and Technical Newsletter #11 that it will continue evaluation of this technology after the proposed modifications have been made and qualified, but will not be adopting the current version into JIG Standards.
FILTER ELEMENT PERFORMANCE IN FIELD TRIALS
The Field Trials for the Water Barrier Filter (CDFX) produced by Parker Velcon have shown so far that the technology is effective in removing water from fuel. However, it is also showing variable service life due to reaching maximum differential pressure (dP).
The technology has rapidly reached maximum dP at locations where the fuel was confirmed on-specification and other filtration technology in use at the same location was not affected. A total of 12 sets of elements has already reached the maximum 22psi.
Laboratory work conducted by Parker has revealed ultra-fine particulate build up on the filtration media. This is the presumed cause of premature high dP, though the underlying sources and likely occurrence of particulate build-up remain unknown.
Whilst the Trials may not reflect conditions experienced at all locations, Operators considering this technology should be aware that the achieved volume throughput, if repeated at a major hub location, would require very frequent change-out of elements.
FACET WATER CONTAINMENT TECHNOLOGY
This technology remains in product development stage. Progress has been presented to Industry Groups on various occasions and the manufacturer is continuing to work with the EI and the engine/airframe OEMs on questions that have been raised. There is still no Qualification Standard written by the EI for this technology, meaning that this technology – or a further development of the concept – will not be adopted into the Standards in the next 1-2 years and may never be.
JIG has set a date of July 2023 to no longer reference EI1583 qualified Filter Monitors in the Standards (Bulletin 132).
Field Trials are continuing and this page will be regularly updated on progress. JIG publishes periodic Technical Newsletters (link to TN #11) to keep members informed about the Field trials and any other information related to filter-monitor phase out.
