Industry’s Filtration Partner
All-polypropylene nominally rated depth cartridges for economical prefiltration

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.
