Parker Polyflow-G Depth Cartridges

Parker Polyflow-G Depth Cartridges
Polyflow®-G depth media has been developed for a wide variety of general process applications from fluid clarification to general prefiltration. Its high dirt-loading, random fiber polypropylene depth media provides consistent particle retention. Polyflow®-G is thermally bonded from 100% virgin polypropylene to ensure clean filtrates and excellent chemical and thermal compatibility in the most demanding processing conditions.

Polyflow®-G leads in overall reduction of filtration costs when compared to spunbonded, stringwound, and nominally rated pleated prefilter cartridges. Its longer filtration life reduces downtime due to fewer changeouts.

  • High flow rate and long service life reduce processing time
  • Broad chemical compatibility allows use in most applications
  • Thermally bonded construction minimizes extractables for cleaner filtrates

  • Liquid clarification
  • General water filtration
  • Beverage/wine clarification
  • RO/DI prefiltration
