Klearfil

Absolute rated pleated cartridge featuring up to eight separate filtration layers providing true depth filtration. This design reduces the fouling of the filter surface area caused by a broad spectrum of contaminants. Ideal for fluids that contain contaminants with a wide range of particle sizes.

Absolute Rated Pleated Depth Filters

A range of absolute rated cartridge filters from Porvair Filtration Group, featuring the latest developments in meltblown polypropylene filter media technology, Klearfil™ cartridges are based on a robust all polypropylene construction, offering removal ratings from 0.5 to 75 micron absolute.

The combination of up to eight separate filtration layers provides true depth filtration, within a pleated cartridge construction. This design will reduce fouling of the filter surface area caused by a broad spectrum of contaminants.

Klearfil™ cartridges are ideally suited for the filtration of process fluids, that contain contaminants with a wide range of particle sizes.

Applications

Klearfil™ cartridges provide absolute filtration where reproducibility and consistency of performance are critical. Suitable for the filtration of aqueous and organic liquids, Klearfil™ cartridges can be used as prefilters or final filters in the following applications:

  • Pharmaceuticals and Bioprocessing
  • Foods and Beverages
  • Process Water Systems
  • Fine Chemicals
  • Cosmetics
  • Graded multi-layer media
  • Full traceability
  • Environmentally friendly
  • Guaranteed removal ratings
    Klearfil™ cartridges are validated using the recognised industry standard modified OSU-F2 single pass test to Beta 5000 (99.98% efficiency).
  • Suitable for steam and hot water sanitisation
    Klearfil™ cartridges are resistant to repeat steam sterilisation up to 135°C (275°F) and hot water cycles at up to 90°C (194°F).

Clean Water Flow Rates

  • Typical clean water flow rate:
    A 254mm (10”) Klearfil™ single cartridge exhibits the flow-ΔP characteristics indicated below, for solutions with a viscosity of 1 centipoise.
  • Other solutions:
    For solutions with a viscosity of greater than 1 centipoise, multiply the indicated differential pressure by the viscosity in centipoise.
