Membrane Filter Cartridges



Polyethersulfone Membrane Filter Cartridges

PES membranes are constructed of hydrophilic, asymmetric polyethersulfone membrane with extended surface area to permit high system flow rate, improved dirt holding capacity and longer on-line service. The absolute rated membranes are available in pore sizes ranging from 0.03 to 0.65 microns.

Materials of Construction

  • Filtration Media — Polyethersulfone
  • Support Layers — Polypropylene
  • Core and Cage — Polypropylene
  • Endcaps and Adapters — Polypropylene



Halar (ECTFE) Membrane

Flotrex HR (FHR) filters are made entirely from Halar* (ECTFE), an industrial-grade fluoropolymer with excellent solvent resistance. FHR filters can withstand the harshest process conditions due to this virtually indestructible material. Providing broad chemical compatibility, you can count on our filters to
produce consistent, uniform process streams in your most demanding filtration applications.

Materials of Construction

  • Filtration Media — Halar Microfiber
  • Support Layers — Halar
  • Core and Cage — Halar
  • Endcaps and Adapters — Halar

Available Absolute Micron Ratings

3, 10, and 25 μm



Hydrophilic Nylon 66 Membrane

Nylon 66 filters have excellent chemical compatibility, making them the ideal choice for a broad range of applications such as high purity water, strong solvents, photoresists and other critical process fluid

Typical applications include:

  • Filtration of Pharmaceutical Intermediates
  • Filtration of Positive Photoresists
  • Final Filtration of Beverages
