AWSS filter cartridges are constructed from 316L grade stainless steel and assembled without the use of resins or adhesives. The filter media is TiG seam welded and the media, centre core and end fittings assembled using the same procedures. AWSS cartridges have an operating range of –150°C to +300°C and up to 25 bar differential pressure. Each AWSS filter cartridge is integrity tested prior to dispatch using a bubble point test in IPA. Media options SSMStainless steel mesh for filtration ratings 2 micron to 840 micron. These cartridges offer high permeability at low cost. SSFStainless steel fibre for absolute filtrationratings of 3, 5, 10, 15, 20, 30, 40 and 60microns. These cartridges offer highpermeability, low differential pressure, high dirt capacity and a beta 5000 absolute rating. SSPStainless steel powder for absolute filtration ratings of 15, 25, 40 and 60 microns. These cartridges are less permeable than the SSF product but are more robust, 100 bar differential pressure rating.

Typically, a flow of at least2 times the forward flow provides good cleaning. Ultrasonic cleaning Again, surface contamination can be removed by ultrasonic cleaning in a bath containing detergent, deeply embedded particulate may not be removed. Chemical cleaning A variety of chemicals (solvents, acids, caustic etc) can be used to dissolve the contaminant or process fluid if it has hardened on contact with air.

High temperature burnout In general, we do not recommend hightemperature burn out for sintered fibre cartridges. Contact European Filter Solutionsfor detailed advice. \\Sintered stainless steel fibre filter cartridges offer high permeability, high dirt holdingcapacity, and absolute micron ratings (beta 5000 99.98% efficient). The sintered fibre filter cartridges are available in plain cylindrical form (0.05m² filtration area per 10” length) or pleated (0.135m² filtration area per 10” length). Both pleated and cylindrical cartridges are fully welded to ensure cartridge integrity and avoid by-pass. Pleated filters are available with a handling cage if required. A full range of endcap styles are available, including 222, 226, DOE, fin, flanged and threaded options, all end caps are fully welded to the pleat pack. Beta 5000 absolute micron ratings (liquid) of 3.0 to 60 are available as standard. Maximum differential pressure in the normal flow direction should not exceed 25 bar, 3 bar in the reverse flow direction (withoptional handling cage), and fibre filters are suitable for operating temperatures between –150ºC and 300ºC. info@europeanfiltersolutions.com F: 01302 595555 www.europeanfiltersolutions.com AWSS Sintered Powder Filter Cartridges Sintered Powder Filter Cartridges Sintered powder filter cartridges are suitable for applications with high temperature and high differential pressure requirements. Although they are typically less permeable than the equivalent fibre product they are extremely robust and suitable for use in the most demanding operating conditions. The Sintered Powder filter cartwide range of materials, including stainless steel, titanium, nickel, bronze, Inconel, Monel and Hastelloy. Available in diameters from 13.5 to 135mm, continuous lengths up to 1500mm, and with a full range of sinter bonded endcaps including 222, 226, flanged, threaded, closed and fin.

High temperature burnout Contact European Filter Solutions for detailed advice. Sintered stainless steel powder is normally formed by compressing a controlled blend of metal particles into their “green” state and sintering them in a controlled atmosphere furnace into a rigid media. The resultant medium is typically between 2-3 mm thick, ungraded through its thickness and has a fairly tight pore size distribution. During the initial compression of the medium, the high pressures gives rise to a smooth surface finish and highdensity media with a maximum voidvolume of around 50%. This lowvoidage and high thickness leadsto low permeability.
