The Aquafil is a non integrity tested PES single layer membrane. This option allows you to purchase a low cost membrane to act as a pre filter to your final filter, ideal for applications where the particle size range is very low but high volume. A 0.45 Biofil can have a 0.45 Aquafil as a pre filter thus taking the load of the final integrity tested filter for half the price.

Single Layer Polyethersulphone Membrane Cartridge Filters

A range of cartridge filters from Porvair Filtration Group, featuring the latest developments in membrane technology, Aquafil™ cartridges are based on a naturally hydrophilic polyethersulphone membrane with a mirrored asymmetric pore structure. When combined with quality all-polypropylene cartridge components and high integrity manufacturing techniques common to all Porvair cartridge filters, the polyethersulphone membrane provides a high strength, long life cartridge.

Features and Benefits

  • Removal ratings
    Aquafil™ cartridges are available in 0.2, 0.45, 0.65 and 1.2 micron.
  • Low protein binding
    Aquafil™ cartridges have excellent low protein binding characteristics, typically 10 times lower than nylon, 2 times lower than polysulphone and similar to PVDF.
  • Will not hydrolyse
    Compared with other membranes such as nylon, the polyethersulphone membrane used in Aquafil™ cartridges is extremely resistant to hydrolysis. Capable of exposure in excess of 2 years, they are ideal for hot deionised water applications.
  • Excellent chemical compatibility
  • Suitable for steam sterilising
  • Full traceability
  • Controlled manufacturing environment
