Characteristics and features
Excellent high-tem resistance and extensive chemical compatibility.
All the compositions reach up to the requirement of the biological testing characteristics of USP Class 6 plastic products at 121℃ and the food contact materials listed in the relevant regulations of Chapter 21 of the Federal Regulations of the United States (CFR). They also conform to the requirements of China's "Standard for Hygienic Safety Evalution of Equipment and Protective Materials in Drinking Water" (2001) for drinking water transport and distribution equipment.
99.99995% bacteria retention in gas and liquid.99.99995% of all kinds of phages, bacteria and particles above 0.01μm were retained during gas filtration.
The sampling of filter element successfully passed the bacterial challenge test required by regulations, LRV≥7.Integrity can be maintained after repeated high-pressure disinfection.
Each filter element should pass the integrity test before leaving the factory. The limitations of integrity testing were correlated with the results of bacterial challenge experiments.
It is manufactured under ISO 9001 and ISO 14001 systems and Class 100 environment.
Production and usage are traceable.
Resistant to repeated steam sterilization.
large air flow, high efficiency and small volume.
