NETTERSHEIM, GERMANY … Eaton's LOFTOP™ and LOFTREX M™ depth filter cartridges ensure the safe and efficient filtration of demanding media such as process chemicals, fine chemicals, acids, alkalis and solvents, as well as paints, lacquers and resins. The Filtration Division of the energy management company Eaton is now expanding its range to include filter cartridges that use polyester as the filter material for particularly high chemical resistance. The new melt-blown polyester depth filter cartridges are not only suitable for a variety of aggressive media, but also provide an alternative to filter cartridges that are bonded with phenolic resin. The entire LOFTOP and LOFTREX M filter cartridge range is now available with polypropylene (PP), polyamide 6.6 (PA) or polyester (PES) filter material.
The filter cartridges are available in different lengths and with all common adapter configurations and sealing materials so that they can be used safely in a wide range of applications and filter housings. LOFTOP depth filter cartridges offer absolute retention rates from 0.50 to 120 μm with a retention efficiency of 99.98%. LOFTREX M depth filter cartridges offer nominal retention rates from 1 to 150 μm with a retention efficiency of 95%.
Demanding applications require suitable filter media
When choosing a suitable filtration system, the chemical resistance of filter materials is one of the most important factors for users in many industries, particularly the chemical production industry. In this industry, many processes involve filtering demanding or aggressive media that would damage unsuitable filter materials. "In the chemical industry, everything interacts with everything else," says Alexander Bachmann, describing the challenge. The senior application engineer of Eaton's Filtration Division states: "For media such as paints and solvents, it is necessary to ensure both chemical and thermal resistance—even in the case of aggressive properties." For various media, these requirements can be fulfilled by filter cartridges that use polyester as the filter material.
"By expanding our filter cartridge range, we can provide users with additional and, above all, reliable options for their filtration processes," continues Bachmann. For example, manufacturers and producers of paint resins have so far relied on filter cartridges bonded with phenolic resin for filtration. Although these filter cartridges offer the necessary chemical resistance, their manufacturing process and disposal means that they are becoming increasingly incompatible with stricter environmental requirements. "Melt-blown polyester filter cartridges provide users with an alternative to filter cartridges that are bonded with phenolic resin," says Bachmann.
Reliable filter materials for all requirements
No matter whether the filter material consists of PP, PA or PES, Eaton's LOFTOP and LOFTREX M depth filter cartridges offer a solution to the many challenges of filtering media safely and reliably in the chemical and other industries. They are made of high-purity microfibers, which are blown in a controlled manner onto an inner core and thermally bonded in the same process step without the use of additives. The filter cartridges do not contain any adhesives or binders. They are individually sealed in foil to reliably prevent cross-contamination prior to installation, and offer a high dirt-holding capacity in a wide range of applications.
