PFA Pleated Filter Cartridge
- Commodity name： PFA Pleated Filter Cartridge
Description
Product Introduction
The filter element is made of polytetrafluoroethylene (PTFE) stretched membrane and PFA skeleton, featuring high throughput, high flow rate, long service life, and excellent chemical compatibility and oxidation resistance. This filter element is widely used in chemical filtration for various acids, alkalis, organic solvents, and other chemicals, meeting the filtration needs of most harsh environments.
Performance Characteristics
● Excellent high-temperature resistance and broad chemical compatibility.
● Perfluoropolymer structure, suitable for filtration of various polar acids and alkalis.
● Double-layer membrane structure, absolute bacterial rejection rate.
● Filter cartridge batch sampling has successfully passed the bacterial challenge test required by regulations, LRV > 7, and maintains integrity after multiple autoclavings.
● Each filter cartridge undergoes integrity testing before leaving the factory. All integrity testing limits used have been verified and correlated with bacterial challenge test results.
● All constituent materials comply with the biological testing characteristics of USP Class 6 121°C plastic articles and meet the requirements for food contact materials as listed in Chapter 21 of the US Federal Regulations (CFR).
● ISO 9001 and ISO 14001 systems.
● Traceable product production, testing records, and usage.
