The Ultipor GF-HV filter is well suited for slurry filtration applications having high viscosities and substantial solid concentrations. Typical high solid concentration fluids include ceramic slurry, metal slurry and conductive paste. In addition, Ultipor GF-HV filters are appropriate for very fine, sub-micron dispersion filtration, such as that used in color resist, inkjet ink, polishing slurry and similar applications.

Pall's Ultipor GF medium is a resin-bonded microfiber matrix designed for fine filtration, low pressure loss and long service life. This resin-bonded structure resists contaminant unloading or media migration.

The unique HV version of the Ultipor GF filter family is specifically constructed for high-viscosity applications where standard media may not be suitable. The combination of a rigid support mesh and a highly porous medium structure provides exceptional flow characteristics, even at very fine sub-micron removal ratings and with high viscosity fluids.
