    Process Filtration PRODUCT DESCRIPTION


    The (P)-SRF filter is a wrapped depth filter with inner and outer guard and end caps made from stainless steel. The retention rate is >/= 99,99998 % related to </= 0,2 m. The binder-free, three dimensional borosilicate depth media has a large void volume of 95 %. This ensures a high dirt containment capacity at a low differential pressure and a high flow rate. The filter media is inherently hydrophobic. Compressed Air Carbon Dioxide Fermentation Air Tank Ventilation Technical Gases

    (P)-SRF
    The wrapped sterile depth filter (P)-SRF is designed and developed for the following applications:

    Filtration of air and gases

    The (P)-SRF was developed for the safe sterile filtration of compressed air and other process gases. The filter element fulfils the high requirements in food (breweries, dairies, soft drinks) and pharmaceutical industries and works reliable even under extreme operating conditions. Based on the patented binder free micro fibre medium made of borosilicate, this depth type filter realises high particle holding capacity and long service life.

    Application areas Chemical industry Pharmaceutical industry Biotechnology Breweries Dairies Aseptic packaging Food industry Hospitals

    All

    requirements for Food Contact Use in accordance with CFR (Code of Federal Regulations) Title 21 and EEC/1935/2004. Several layers of the glass fibre medium are embedded in stainless steel supports and bound to stainless steel end caps. The sturdy stainless steel construction permits one hundred (100) possible sterilisation cycles at specified conditions and withstands high differential pressures in both flow directions. (P)SRF sterile filter elements guarantee a safe and reproducible production.
