PP-Series Overview

The pleated depth media is encapsulated in an integral, continuous-length, thermally-bonded structure for cleanliness, pressure tolerance, and chemical inertness. Offered in both absolute-rated (up to 99.98% retention) and nominally-rated (90% retention) grades in all end configurations. Manufactured in a clean-room environment to maintain high standards of purity and cleanliness. Commonly used in food/beverage and chemical applications as a final filter or prefiltration stage.
