GHPS-Series Polysulfone

GHPS-series high purity polysulfone filter cartridges offer exceptional flowrate and loading capability by virtue of its highly asymmetrical pore structure.

It’s a preferred choice in applications requiring the efficiency of a membrane but where a longer service life is important. Its hydrophilic nature allows immediate wet-out and optimizes the utility of the membrane surface area. Manufactured in a high-purity, thermally-bonded construction for cleanliness and broad compatibility, the optional post-rinse feature provides a cartridge with quick rinse-up to 18 megaohms.
