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.
|Unique matrix with resin-coated fibers||Robust, fixed pore structure||Resists unloading and media migration|
|Capable of filtration down to 0.1 μm||Fine filtration of dispersions||Lower cost for filtration versus membrane filters|
|Excellent particle removal and retention||Consistent and effective filter performance||Reproducible filtrate results from batch-to-batch|
|Optimized pleat spacing with stronger pleat support||Resists pleat deformation under conditions of high viscosity and high flow rate||Longer service life and excellent filter economics|
|Available lab test filter with small effective filter area||Permits testing and scale-up with identical versions of full-size filters||Facilitates selection of appropriate filter and enables prediction of filter |
performance in actual service
|Medium utilizes very fine fibers in filter matrix||Very high void volume and porosity||Excellent flow rates|
