Material of filter element components:


Filter membrane: Hydrophilic PES membrane

Support/Drainage: PP

Core/Cover/End cover/End caps: PP

Sealed leads/Fins: PP with stainless steel inside

O-Ring: 222,226 silicon rubber etc.

Sealing technology: Thermal bonding without adhesives


Characteristics and features

 

  • Excellent high-temp 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 Evaluation of Equipment and Protective Materials in Drinking Water" (2001) for drinking water transport and distribution equipment.

  • 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.

  • Low protein adsorption to make sure the maximum recovery of target active ingredients.

  • The filter membrane has a gradient aperture structure for pre-filtration with large flow rate, low-pressure difference, and long service life.

  • Production and usage are traceable.
