Parker Proflow™-HE Cartridge

Pleated Hydrophilic PTFE Membrane and Polypropylene Supported Cartridges for Microelectronic Liquid

The Proflow™-HE cartridge is designed for filtration of microelectronic (MiE) fluids. High-purity polypropylene and hydrophilic PTFE provide an economical alternative for the filtration of various MiE chemicals. The hydrophilic nature of the PTFE membrane does not require pre-wetting for aqueous based liquids typically necessitated with standard PTFE membranes. This can reduce total operating cost and improve process up-times.

Proflow-HE is available in both Standard and SELECT pleated versions. SELECT pleating allows for additional membrane surface areas for exceptional flow rates and on-stream life.

Proflow-HE cartridges are manufactured in an ISO 9008 certified Class 10,000 cleanroom and flushed with ultra-high-purity deionized water and 100% integrity tested as well as serialized to provide complete product purity, reliability and traceability.


  • Recommended applications include, but are not limited to:
  • Acids & Bases
  • Extraction/crystallization solvents
  • Hot ultra-high-purity deionized water
  • Solvent filtration


  • Hydrophilic membrane (pre-wetting not required)
  • Broad chemical compatibility
  • Long service life minimizes changeout frequency
  • Low differential pressure reduces energy costs
  • Top-performing retention efficiency
  • Very low metals and organic extractables
  • Quick rinse up-time
  • Integrity-tested for quality assurance


Proflow-HE is well-suited for the manufacturing of:
  • LCD Displays
  • Solar Panels
  • Bulk Chemicals
  • Fine Chemical Filtration


Materials of Construction
Membrane:     Hydrophilic PTFE
Support layers:     Polypropylene
Structure:     Polypropylene

Materials are thermally bonded, for maximum assurance of filter integrity and elimination of bonding or sealing compounds. Modules and final filter assemblies are flushed with 18-meg-ohm-cm high purity water, to provide extremely low extractables levels.
