The BSE class absolute filter cartridges are made of polypropylene. Thanks to unique technology of production the cartridges ensure filtration efficiency level of 80 % for particle sizes encoded in the identification markings. BSE cartridges consist of a single layer of fibres wound on a polypropylene core. Filters are also available in a coreless version.

BSE cartridges consist of a single layer of fibres wound on a polypropylene core. Filters are also available in a coreless version.

Perfect for applications where effective protection against such contaminants is required. They protect household appliances, 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 BSE cartridges use their entire volume for filtration and therefore they have a very long service life, while offering high performance and constant efficiency. BSE series cartridges are available with core or in a coreless version. The inner core 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, BSE cartridges belong to the group of the so-called economic filters. This means that the filtration efficiency for example for a particle size of 1 micron is over 80. 00%, that is only 1 in 5 particles of a given size can pass through the filter. BSE cartridges are mainly used in water treatment for household needs. In contrast to the FRE series filters, they have a larger filtration volume, absorbency and durability.
