The LC-Series PTFE filter cartridge features ultra-high chemical stability and strong hydrophobicity, making it an essential gas filtration component for fluorinated fluid immersion liquid cooling. It can be used in scenarios such as exhaust vents, balance pipes, and system ventilation to prevent moisture and particulates from entering the refrigerant, providing semiconductor-grade particle control and protecting the purity and dielectric properties of HFE/HFO coolants. The cartridge features ultra-low extractables, high temperature tolerance, and each unit is independently tested before leaving the factory to ensure long-term stable operation.
