KFM.F Capsule filter for filtration of gas and air

KFM.F Capsules by Technofilter RME Ltd are produced on the basis of fluoroplastic hydrophobic membrane F42 and are used for finish treatment of gaseous media in medicine, microbiological industry, pharmacy, food and other industries, for removal of mechanical impurities and microorganisms with the size above or equal 0.45 μm.

Main applications

  • For finish filtration of compressed air and gases, CO2
  • For removal of particles and “mist” in the laboratory air supply.
  • For ventilation of containers (“tank breathing”).
  • For protection of air used in different devices.
  • For polishing and sterilization of non-aqueous media, aggressive liquids compatible with filter’s materials.

Sterilization by autoclaving


Sanitization and sterilization

Sterilization of Capsule filters is performed by autoclaving at temperature 121°С for 30 minutes after attainment of set-point temperature.

KFM.F Capsule filters are able to withstand at least 50 (много) sterilization cycles by autoclaving at P = 0,1 MPa and  t=126 ± 1о С. Note! It is prohibited to sterilize Capsule filters by steam-in-line.   

KFM.F4 Capsules are compatible with wide variety of chemical substances.

For detailed instructions on operation Capsules please contact technical specialists of Technofilter RME Ltd. 

Quality and safety

All membrane filter cartridges used for production of KFM.F Capsule filters are subjected to wash out from organic and mechanical impurities with high-purity water and to 100% integrity control.  

Capsules produced by Technofilter RME Ltd are added to the Register of Medical Devices of the Ministry of health of the Russian Federation.

Capsule filters are certified for use in Medical Industry and Sanitary and Epidemiological Station, they are authorized to use in Food industry. Safety of filter cartridges is determined by a series of sanitary and chemical tests, and toxicology tests in compliance with GOST R ISO 10993.1-99, GOST R ISO 10993.5-99, GOST R ISO 10993.10-00.
