KFBZh and SV fiber-glas disk prefilters on the basis of natural and mineral fibers are used for prefiltration of liquids with high level of particle separation. These are depth filters, which significantly reduce final membrane filter loading. Glass-fiber prefilters are installed in a special disk filter holder directly on the membrane filter and are intended for prefiltration of highly polluted solutions.

Features and applications

Features and advantages

  • Biologically inert towards fluids to be filtered.
  • Combine high filtration capacity and retention effectiveness.
  • Wide chemical compatibility towards the majority of reagents and solvents as well as concentrated acids.

Glass-fiber discs are used for preliminary and bioburden reduction filtration of:

  • biological fluids,
  • pharmaceuticals,
  • paranterals,
  • blood serum.
