FNA FILTERS

Nylon filter cartridges of the FNA series due to the type of impurities removed belong to the group of mechanical filters with an absolute filtration efficiency of 99.98%. They are used for removing suspensions, rust and solid sludge from liquids.

Perfect for applications where effective protection against such contaminants is required. They protect the equipment, installations, systems and fittings, prolonging their service life. The filter is made entirely of pure high-quality polyamide 6.6, FDA-approved. It retains all the advantages of the original material including: high chemical, mechanical and thermal resistance. Cartridges made of polyamide 6.6 enable contact with almost all types of liquids, in particular with organic solvents, fuels, vegetable oils and mineral oils. The internal filter structure is obtained without the addition of any plasticizing agents, adhesives or other binder components. Due to “melt-blown” production technology, these cartridges offer excellent efficacy, and in addition small flow resistance, very high absorption capacity and stiffness of the whole structure. They operate correctly even at high differential pressures. The FNA cartridges use their entire volume for filtration and therefore they have a very long service life, while offering high performance and constant efficiency. In addition, they have an inner core made of fibreglass reinforced polyamide, which significantly increases their resistance to pressure spikes. In the case of mechanical damage to the cartridge, the core also prevents the release of fibres to the filtered liquid. Due to filtration effectiveness, FNA cartridges belong to the group of the so-called absolute filters. This means that the filtration efficiency for example for a particle size of 1 micron is over 99. 98%, that is only 1 in 5000 particles of a given size can pass through the filter. For larger particles, the efficiency is, of course, 100%. FNA cartridges are used primarily for treatment of non-polar liquids for semi-industrial and industrial purposes.
