RJMPES Polyethersulfone Pleated Membrane Filter Cartridges

  • Absolute filtration rating
  • Long service life
  • Both Economic and Premium PES Membrane options
  • Non-shedding membrane

The Baleen Max F.E. RJMPES filter cartridges are constructed with Sulfonated Polyethersulfone (PES) pleated membrane filtration media offered in both economical and premium options. The symmetrical pleated design combined with our membrane technology brings a large surface filtration area of 8.08 ft.² per 10” cartridge, (0.75 m² per 10” cartridge), with a superior retention efficiency. The Polyethersulfone (PES) media is a non-shedding material that we offer in absolute fixed pore ratings of 0.1µ, 0.2µ, 0.45µ, 0.65µ, and 1µ for excellent capabilities in particle removal and bacteria retention. With thermally welded Polypropylene (PP) cores and end caps to promote a wider array of compatibilities while working to prevent any contamination of treated liquid.
