FluoroPFA® Filter Cartridges

All-Polyfluorene Filter

Hall Pyke FluoroPFA® Filter Cartridges utilize expanded PTFE membranes and PFA core & cage to meet critical filtration requirements in extremely aggressive environments. PFA Filters remain strong and durable in aggressive acids, bases, and organic compounds. In addition, hydrophilic PTFE membranes require no pre-wetting.

Features and Benefits

  • All-fluoropolymer material of construction provides superior resistance during chemical processing and pulsing.
  • Excellent chemical compatibility.
  • High temperature and pressure capabilities.
  • Very high flow rates with low differential pressure.
  • Low extractable.
  • High particle removal efficiency.
  • Manufactured in a clean room environment.

Typical Applications

  • Highly corrosive Acids, such as Hydrofluoic Acid, Nitric Acid and Sulfric Acid.
  • High Temperatures Chemical Liquid (>100°C).
  • Aggressive Solvents, such as Chloroform, Two methyl, Isopropyl Alcohol.
  • Aggressive Bases.
  • Oxidizing Air/Gas.
