The CLN class absolute filter cartridges are made of polypropylene. Thanks to unique technology of production the cartridges ensure filtration efficiency level of 95 % for particle sizes encoded in the identification markings. CLN cartridges consist of two successive layers of fibres forming a uniform filtration structure.

The CLN class absolute filter cartridges are made of polypropylene. Thanks to unique technology of production the cartridges ensure filtration efficiency level of 95 % for particle sizes encoded in the identification markings. CLN cartridges consist of two successive layers of fibres forming a uniform filtration structure. The outer layer serves as a pre-filter, and the inner layer acts as a final filter. The filter is also available in a single-layer version.

Perfect for applications where effective protection against such contaminants is required. They are designed in such a way as to stop the contaminant particles with extremely high efficiency, while maintaining low flow resistance and high absorbency. 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 CORELESS cartridges use their entire volume for filtration and therefore they have a very long service life, while offering high performance and constant efficiency. CORELESS (CLN) cartridges have a double layer structure. The outer layer with greater micronage acts as a pre-filter performing coarse filtration, while the main filtration is performed in the inner layer. This ensures better utilization of the filter volume, protects the outer layers against clogging and extends cartridge’s service life. Filters are also available in a single-layer version. Due to filtration effectiveness, CORELESS (CLN) cartridges belong to the group of the so-called nominal filters. This means that the filtration efficiency for example for a particle size of 1 micron is over 95%, that is only 1 in 20 particles of a given size can pass through the filter.
