Fluorofil™ Plus

High Flow Sterile Gas Filter with ePTFE Membrane

Fluorofil™ Plus cartridges are manufactured using a highly hydrophobic ePTFE membrane. The enhanced ePTFE membrane offers exceptionally high gas flow rates at low pressure differentials (see graph). Fluorofil™ Plus cartridges are recommended for sterile gas filtration and venting applications. The hydrophobic characteristics of the ePTFE membrane makes the Fluorofil™ Plus filter cartridge particularly suitable for wet gas sterilising applications, such as fermenter air feed.

Features and Benefits

  • Guaranteed microbial ratings in a liquid challenge
    Fluorofil™ Plus cartridges are validated for bacterial removal according to
    HIMA guidelines and ASTM F838-05, with a log reduction value >7.
  • High Flow ΔP characteristics
    The unique characteristics of the ePTFE membrane, having higher surface area, combined with the construction of the Fluorofil™ Plus filter cartridge, results in exceptionally high gas flow rates at low pressure differentials. These features result in lower energy consumption and fewer filter cartridges per system.
  • Mechanical strength
    Fluorofil™ Plus cartridges incorporate a stainless steel central core which provides greater mechanical strength. This allows the filter to be used at higher gas flow rates with low pressure differentials.
  • Cartridge integrity and low TOC levels
    All Fluorofil™ Plus cartridges are integrity tested and supplied clean, having been flushed with pure water.
