RJMHP Hydrophilic Polyethersulfone Pleated Membrane Filter Cartridges

  • Excellent particle retention and superior flow rates
  • Broad chemical compatibility for wide array of applications
  • Exceptional on-stream life
  • 100% integrity tested

The Baleen Max F.E. RJMHP filter cartridges are constructed with Hydrophilic Polyethersulfone (PES) pleated membrane filtration media for use in aqueous applications. Offering a broad chemical compatibility, a very low level of ionic and organic extractables, and a superior resistance to particle shedding. Making these products well suited for applications involved in microelectronics manufacturing such as DI water treatment and aqueous based chemical treatment. The unique mirrored-anisotropic membrane allows for exceptionally high flow rates and a long on-stream lifespan while efficiently providing consistent removal of both organic and inorganic particles. The RJMHP product line is manufactured in a ISO-certified clean room environment and pre-flushed with 18 megohm-cm ultrapure DI water before final integrity testing of every product.


The RJMHP pleated membrane products have a wide array of applications including, but not limited to, the following:

  • BOE
  • Dilute HF
  • POU DI Rinse
  • Bulk DI Water Systems
  • Copper Plating
  • Nickle Plating
  • Hard DiskWash Processes
  • Other Dilute Acids and Bases
