Polysulfone Membrane

MicroVantage™ WGPS Series

Water Grade Polysulfone Membrane Filter Cartridges




  • Absolute retention ratings from 0.03 to 1.0 microns
  • 6.0 square feet (0.56 m2) of media surface area per ten inch length for optimal performance
  • Highly tapered asymmetric pore structure provides excellent flow rate and dirt holding capacity
  • Cost effective absolute filtration for less critical applications -not integrity tested
  • Rigid, molded cage protects pleated media and strengthens structural stability
  • Manufactured in state-of-the-art white room for high purity
  • Complies with Food & Drug Administration’s CFR criteria for food & beverage contact.
  • Meets USP Class VI Biological Test for plastics
  • Available in common and end cap configurations to fit most filter housings
  • Produced in standard lengths up to 40 inches
