Hydrophobic Polysulfone (PSH) Membrane Cartridge

Hydrophobic Polysulfone Membrane Cartridges provide a highly cost-effective alternative to PTFE or PVDF membrane cartridges for air, bulk gas, and tank vent applications. PSH cartridges offer high moisture resistance and high flowrates at low pressure drops. Constructed using high purity polypropylene hardware and the latest thermal-bonding equipment, PSH series cartridges offer an outstanding value.

Excellent chemical compatibility. 
  • Suitable for filtering organic solvents and acid bases. 
  • Pleated design for increased surface area.
  • Low pressure loss and longer service life.
  • Retention rating down to 0.02 μm.
  • Graded pore density for higher dirt holding capacity.
  • Rigid polypropylene outer cage protects filter media.
    Manufactured from materials which are listed for food contact applications in Title 21 of the U.S. Code of Federal Regulations.
  • Cartridges are free of binders, resins, and adhesives.
    All polypropylene components meet the specifications for biological safety per USP Class VI – 121 ̊C for plastics.
