Filtration installations





Hydrophobic cartridge filter elements having an absolute filtration rating for sterilizing filtration of compressed gases, air and carbon dioxide in Medical, BioPharmaceutical, Food, Electronic and other industries.

Filter material

Pleated hydrophobic membrane PTFE. Core, outer shell and end parts: polypropylene having increased heat resistance. O-rings: silicon (optionally Viton, fluorine rubber).

Main applications
  • Sterilizing filtration of air and gases that enter into critical contact with the product
  - in air supply systems
  - in storage tanks to create sterile breathing conditions
  - upstream of filling machines
  - at the points of entry and exit of bioreactors
  • Sterile filtration of fermenters
  • Sterile blowout of equipment
  • Filtration of liquid aggressive media (acids, alkalies, solvents, process liquids) in the pH range 1 to 13



Advantages for customers

Membrane made of polytetrafluoroethylene (PTFE)

Broad chemical compatibility. Excellent heat resistance

Special structure of the membrane

  • Excellent filtration characteristics, comparable to those of the best world analogues
  • High flow rate and low flow resistance
  • Increased dirt holding capacity and extended service life

High strength of the filter element

  • Reliable retention of integrity in severe operating conditions
  • Capable of withstanding multiple sterilization cycles at 134°C
  • Complete retention of bacteria and aerosol particles in compressed air and gas flows
  • Guaranteed retention of integrity after numerous sterilization cycles

100% integrity control

  • Integrity control is performed in the ‘dry' mode for aerosol particles and in the ‘wet' mode by the diffusion test. Guaranteed integrity and effective operation of the device
