Home - Products - Filter cartridges

"Technofilter" produces a wide range of filter elements of various types, from deep prefilter filters to sterilizing membrane filters for final cleaning, made in the form of standard filter cartridges, cartridges, mini-cartridges and capsules.

 Filter cartridges

The standard filtration cartridge of  Technofilter LLC is a cylinder with a diameter of 70 mm and a height of 250 mm with an internal perforated polypropylene casing around which layers of various filter materials are located. The outer perforated housing provides mechanical strength of the cartridge during filtration, washing and sterilization.

On the basis of standard elements, filter cartridges with a height of 500, 750 and 1000 mm are produced. Sealing of joints is carried out only by heat-sealing without the use of adhesives, excluding extraction of components.

To increase the surface area of the filtering surface, we use the corrugation technology, in which the layers of the filter material are superimposed on one another and are laid with corrugations around the perforated inner case.

For the first time in Russia the technology of corrugation in the manufacture of cartridge filter elements was developed and applied by the company "Technofilter".

Our corrugating technology allows us to achieve an increase in the area of the filtering surface of the filter element up to 1 m2 (for the element with a height of 250 mm) with the maximum access of liquid (or gas) to the entire area of the filter element, ensuring a high resource and dirt capacity of the product.

In addition to corrugated filter elements, we produce coiled and bulk cartridges.

Classification of produced cartridge filters by the mechanism of particle confinement

  • membrane (the surface confinement of particles predominates)
  • depth corrugated (combination of surface and depth mechanism)
  • deep fiber (particle retention occurs in the volume of the filter material)
  • sorption-filtering (particle retention occurs due to adsorption mechanisms)
  • mesh stainless steel (sieve retention mechanism)


Mini-cartridges are a reduced version of a standard cartridge with a diameter of 70 mm and a height of 100, 125 and 150 mm. Like the standard cartridges, mini-cartridges are produced on the basis of various filtration materials. Mini-cartridges are used in the same areas as standard cartridges, but when smaller volumes are to be filtered.

Capsule filters

Capsules are ready-to-use complete integral filters, which are mini-cartridges sealed in polypropylene holders. The design allows the use of capsules without the installation of a steel casing.

Capsules are designed for fast, efficient and economical filtration of small volumes of liquids and gases. Capsule filters allow small-scale pilot tests to be carried out early in the development of a filtration system to select the optimal combination of filters, especially for the treatment of difficult-to-filter solutions without investing in stainless steel equipment.

The capsule filter has a high-strength, hermetic polypropylene housing and is equipped with various filter materials with a wide range of pore sizes.

The filter capsule of the standard type consists of a polypropylene outer casing with a diameter of 92 mm with a cartridge-type element pressed into it with a height of 60 mm, 125 mm or 250 mm with a filter surface area from 0.2 to 0.85 m².

Mini Capsules

To filter small lots of expensive products and other applications, our company has developed a special design of a mini-filter.

Minicapsule - is a non-removable filter 100 mm high and 48 mm in diameter, consisting of a polypropylene outer casing with a membrane or corrugated cartridge element pressed into it with a filter surface area of up to 0.07 m² (700 cm2).
