	Monitor Change Out Pressure Facet Engineering, 1 June 2007 The Facet bulletin issued October 2006 (see below) addressed lowering the differential pressure for change out of monitors to 15 psi because of the concerns over media migration. Substantial work has been done since then regarding media migration on monitors both at the beginning and end of cartridge life. The results of these tests indicate that the potential for media migration has been substantially lowered with the addition of numerous manufacturing changes. In addition, quality control testing is now being performed with the sole purpose of identifying media migration. Based on this information, the change out pressure for 2 inch monitors and 6 inch outside-in (FG-O) can be returned to 22.5 psid (1.5 bar). To date, there is insufficient test data on 6 inch inside-out (FG-I) monitors to draw the same conclusion, so the change out pressure for FG-I series 6 inch monitors will remain at 15 psid.

March 2007	Key Points Summary of API 1581 5th Edition. (Facet, March 2007) Nine key points explained on major and minor differences between API 1581 3rd Edition and the current API 1581 5th Edition. For more specific questions, call us for assistance. Click here to read the full white paper.
December 2006	VF21-22 Series Housings with Pre-blended Fuel. (Facet, 22 Dec 2006) Recent testing utilizing stock CC-21-7 and CC-22-7 coalescers indicate performance meeting API 1581 effluent criteria can be achieved at reduced flow rates when compared with fuel without FSSII. The tests were performed on Category M type fuel in accordance with the specification and utilizing the S-LW criteria for 0.5% water maximum. The recommended flow rates are: - VF21 housing using CC-21-7 coalescer element 15 GPM - VF22 housing using CC-22-7 coalescer element 22 GPM Development continues on new coalescer models for pre-blended fuel that will allow higher flow rates.

October 2006	WARNING on Use of Aviation Fuel Filters (Fuses) 'Qualified to" IP 1583 4th Edition or Earlier Editions (Issued by IP - 19th October 2006). Aviation fuel filter monitors (fuses) containing water absorbent polymer have been used for many years to prevent water and dirt being delivered to aircraft during refueling operations. In recent years it has been determined that FILTER MONITORS 'QUALIFIED TO' IP 1583 4TH EDITION OR EARLIER EDITIONS CANNOT BE REGARDED AS FAIL-SAFE DEVICES FOR PREVENTING WATER BEING DELIVERED TO AIRCRAFT. IT HAS ALSO BECOME APPARENT THAT WATER ABSORBENT POLYMER FROM SUCH ELEMENTS MAY MIGRATE DOWNSTREAM. However. in many operations filter monitors continue to form on component in the comprehensive system to control dirt and water in aviation fuel. RECOMMENDED ACTION TO BE TAKEN BY FILTER MONITOR USERS........read more Click here to read the enitre DRAFT Release from the IP.
July 2006	Shell Aviation AOTB 2006/03. Filter monitors: Restrictions for use. Filter monitors are currently the preferred filter type for into-plane use because of their ability to remove dirt and absorb water from fuel. However, recent performance issues have led to further restrictions on their use, in particular the requirement to avoid using filter monitors with jet fuels doped with FSII.

July 2006	Facet’s New 5th Edition Qualified Coalescer/Separator Cartridges. (Facet, July 2006) This new technology allows Facet customers to convert their existing 3rd edition vessels to 5th edition without reducing the flow rate. We can also offer 5th edition vessels equivalent in size to 3rd edition vessels. Flow rates are slightly less when using Teflon® separators.
May 2006	Velcon Filters, Inc. Recommends Discontinuing the Use of Water Absorbing Cartridges with Pre-Mixed Fuel Containing Anti-Icing Additives. (Velcon, 30, May 2006) During the Coordinating Research Council (CRC) meeting in May of 2006 it became clear to Velcon that although very clear guidelines exist for the safe operation of pre-mixed fuel, it has proven difficult for operators to ensure that the water absorbing cartridges are being operated correctly. Following the CRC meeting ...Velcon Filters, Inc. has concluded that effective immediately, the use of water absorbing cartridges with commercial fuels (Jet A and Jet A1) continuing anti-icing additives should be discontinued.

March 2006	Technical Bulletin - IP 1583 Monitor Specifications Update (Facet, 13 March 2006) Recent incidents in the aviation industry have indicated Fuel System Icing Inhibitor (FSII) adversely affects the water removal properties of filter monitors and has also been implicated in media migration............ The USAF identified problems with monitors in JP-8 fuel and had aircraft incidents related to media migration of CMC, an adsorbent NOT PRESENT IN FACET MONITORS.
