I am interested in KFM.F4 Please call me back

KFM.F4 Capsules are produced on the basis of hydrophobic fluoroplastic (PTFE) membrane especially developed for finish treatment of gases and air in the critical contact with product. KFM.F4 Capsules are used for sterilizing filtration of gaseous media in medicine, microbiological industry, pharmacy, food and other industries.

KFM.F4 are disposable filters.

Features and applications

Main applications:

  • Sterilizing filtration of compressed air and gases, CO2. 
  • Removal of particles and “mist” in the laboratory air supply.
  • Ventilation of containers (“tank breathing”).
  • Polishing and sterilization of non-aqueous media, aggressive liquids compatible with filter’s materials.
Specifications

Construction and materials

KFM.F4 is a one-piece filter consisting of a polypropylene outer body with a cartridge-type membrane element pressed into it with a filtering surface area from 0.07 (mini-capsules) to 0.4 m².

Standard KFM.F4 are manufactured with two types of connections: threaded conical 1/2 "and sanitary flange type triclamp. Capsules are produced with hygienic openings for air release (1/4" outlet valve).

Sanitization and sterilization

Sterilization of Capsules is performed by autoclaving at temperature 126°С for 30 minutes after attainment of set-point temperature.

KFM.F4 Capsules are able to withstand at least 30 sterilization cycles by autoclaving at P = 0,1 MPa and t=126 ± 1° С. Note! It is prohibited to sterilize Capsule by steam-in-line.

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

Safety

Quality and Certification 

All membrane filter elements used for production of KFM.F4 Capsules are subjected to wash out from organic and mechanical impurities with high-purity water and to 100% integrity control.

KFM.F4 Capsules are added to the Register of Medical Devices of the Ministry of health of the Russian Federation.

The Capsules 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.
