Filter cartridges are used for drinking and process water purification, alcoholic and non- alcoholic beverages, juices, beer, milk, vegetable and mineral oils, and liquid paint and varnish materials from mechanical particles larger than 0.5 microns of. It are applied as pre-filters to protect following filters, reverse osmosis, ultrafiltration and other equipment, also as the final stage of cleaning.

Structure of the filter cartridge

The filter cartridge for liquids purification from mechanical impurity is a multilayered cylindrical design from nonwoven polymeric fibrous fabric with the variable pore size over the filter layer.

Structure of the filter cartridge is formed by of the analysis of particle size distribution of solid particles in the liquid and technological parameters of process of a filtration. Each structural element provides compliance of a certain parameter of the filter cartridge with the specified requirements. This approach allows to adapt the filter cartridge to specific operating conditions and to provide an optimality of his characteristics.

Modern processing equipment with high extent of automation allows to carry out quickly multiple parameter optimization of structure of the filter cartridge. In combination with continuous control of parameters of the filtering elements, it allows to receive high-quality products for the most various scopes.

We recommend filter elements for:

  • drinking, technological and turnover water;
  • alcoholic and soft drinks, juice, beer;
  • chemical reactants, acids, alkalis, organic substances, galvanic solutions, removal of firm catalysts, etc.;
  • liquid varnishes and paints;
  • vegetable and mineral oils;
  • air and gases in case of normal and raised (to 80 °C) temperature;
  • for removal of opalescence and colloids from various liquids.

Distinctive features of our filter cartridges:

      • the regulated change of pore size of a deep filter layer allows to make the filter cartridges combining the finish filter and the prefilter;
      • multilayer porous structure provides increased dirt holding capacity;
      • lack of migration of fibers from a filter-bed;
      • high chemical resistance to a wide range of chemical reagents;
      • low content of the extracted substances binding absence, lubricants and surfactants in case of production;
      • broad range of working temperatures (to +80 °C);
      • low cost;
      • when filtering water solutions the preliminary gidrofilization isn't required;
      • a wide range of filter cartridges with removal rating from 0,5 to 100 μm;
      • the nomenclature of the filtering elements of various length for ensuring required performance of process of filtering.
