Description
Duredunty ® Fillter Cartridges are made of a unique 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 excellent sterilization
· Asymmetric pre-filter layer has a longer life and reduces filtration costs
· Broad chemical compatibility (pH 1-14)
· Integrity Testable
Quality Standards
· Tested with B.diminuta (ATCC 19146 at 108 -1010 /cm² (＞99.999999%)
· Manufactured under ISO 9001:2000
· Each element is individually Integrity Tested
