Industry’s Filtration Partner
Pleated polypropylene absolute-rated depth cartridges with superior dirt-holding capacity

Polyflow®'s random fiber polypropylene depth media provides long on-stream life and high retention efficiencies. While many polypropylene depth media are nominally rated and cannot meet their actual claimed retention efficiency, Polyflow® is engineered to meet exacting performance claims.

Parker's innovative research team developed an exclusive calendaring process that produces media with unsurpassed dirt-loading capacity. Before each lot of media is fabricated, the best calendaring conditions are determined to ensure minimal lot-to-lot variability and peak product performance. The number of pleats for each filter rating has also been optimized to ensure maximum dirt-loading capacity and on-stream life.

Polyflow® is thermally bonded from 100% virgin polypropylene to ensure superior cleanliness and excellent chemical and thermal compatibility under harsh processing conditions.
