PLPF Series All Fluoropolymer Filter Cartridge with Hydrophilic PTFE Membrane for Chemical Corrosion Resistance and Low Precipitation

PLPF series filter cartridge adopts hydrophilic Polytetrafluoroethylene (PTFE) filter membrane, with outer cage, center core and end caps all made of PFA material. This construction provides exceptional chemical corrosion resistance and low precipitation characteristics, ensuring highly efficient, long-term filtration of strong corrosive acids, alkalis, and organic solvents.

• Excellent Chemical Compatibility: Perfluorinated structure provides exceptional resistance to high temperatures and corrosion, suitable for filtration of high-temperature, highly corrosive chemical liquids in microelectronics and semiconductor industries.
• Low Precipitation: Utilizes high-purity materials (DuPont HP440 or Daikin 231SH) with non-contact welding technique during manufacturing, without additives or adhesives, ensuring low precipitation and safe usage.

• Food & Beverage: Hot water sterilization to reduce bacterial contamination risk
• Pharmaceutical: Process water filtration to improve product consistency
• Oil & Gas: Hot water filtration for drilling and utility water processes
• Chemical Processing: Filtration of process water in high-temperature operations
• Industrial Manufacturing: Power generation, steel production, automotive manufacturing, and other high-demand processes

We provide technical support for installation, operation, and maintenance, as well as routine services such as filter replacement guidance and maintenance recommendations. Comprehensive documentation is available, including user manuals, installation guides, and troubleshooting notes.
