Duredunty Filter Cartridges

Double-layer PES Membrane · Sterilizing Grade

Duredunty^® Filter Cartridges are made of a double-layer PES membrane and designed for use in beverage and pharmaceutical applications including particles, cysts, oocysts, and bacterium in the water. They provide superior flow rates and high particle removal efficiency when compared to other sterilizing grade filter cartridges.

Features and Benefits

Double-layer membrane provides great sterilization
Asymmetric pre-filter layer has a longer life and reduces filtration cost
Broad chemical compatibility (pH 1-14)
Integrity Testable

Quality Standards
