Characteristics and features

  • Excellent high-tem resistance and extensive chemical compatibility.

  • All constituent materials comply with the biological test characteristics of USP Class VI 121 ℃ plastic products, and comply with the food contact materials listed in the relevant provisions of Chapter 21 of the United States Federal Regulations (CFR).

  • Excellent hydrophilicity, suitable for sterilization and filtration of strong acid and alkali liquid.

  • 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.

  • Large air flow, low differential pressure and long service life.
