High purity pleated polypropylene filter media provides a high area, 100% polypropylene element for removal of fine or coarse particulate from fluid streams. 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. Commonly used in food/beverage and chemical applications as a final filter or pre-filtration stage.
