Thanks to unique technology of production the cartridges ensure filtration efficiency level of 99,98 % for particle size encoded in the identification markings. FRA cartridges consist of two layers of fibres wound on a polypropylene core. The outer layer serves as a pre-filter, and the inner layer acts as a final filter.

The FRA class absolute filter cartridges are made of polypropylene. Thanks to unique technology of production the cartridges ensure filtration efficiency level of 99,98 % for particle size encoded in the identification markings. FRA cartridges consist of two layers of fibres wound on a polypropylene core. The outer layer serves as a pre-filter, and the inner layer acts as a final filter. This also applies to the filters with filtration performance of 0,5μ, 1μ, 3μ, 5μ, other filter cartridges have only one layer.

Perfect for applications where effective protection against such contaminants is required. They protect the equipment, installations, heating systems and fittings, prolonging their service life. The filter is made entirely of pure high-quality polypropylene, FDA-approved. It retains all the advantages of the original material including: high chemical, mechanical and thermal resistance. 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 FRA cartridges use their entire volume for filtration and therefore they have a very long service life, while offering high performance and constant efficiency. Additionally, they have an inner core, 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, FRA 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%. FRAP cartridges are used primarily for water treatment for semi-industrial and industrial purposes. They are used with Standard and Hydro series filter housings, type FP2 and FP3 as well as industrial steel housings.
