The hydrophobic filters incorporate Gore's proprietary high-flow ePTFE (expanded polytetrafluoroethylene) filtration media.
 

Applications for the hydrophobic filters from Gore include high-throughput filling, packaging and recirculation systems for high-viscosity fluids, acids, bases, solvents, specialty chemicals and other high-purity chemicals used in semiconductor and electronics fabrication. The hydrophobic filters are available in a pore size rating range from 0.1 to 0.03 µm.
