PLPV / PLPVH Series Corrosion Resistant PVDF Filter Cartridge
PLPV / PLPVH Series corrosion resistant PVDF filter cartridge is designed for strong corrosive chemical filtration and high-temperature chemical liquid filtration. This series uses PTFE membrane as the filter media, with PVDF outer cage, center core and end caps. The PVDF structural components provide excellent chemical resistance and high temperature resistance, while the PTFE membrane delivers high filtration efficiency and reliable particle retention.
PLPV Series adopts hydrophobic PTFE membrane, suitable for strong corrosive acids, alkalis, organic solvents, and special chemical filtration. PLPVH Series uses hydrophilic PTFE membrane, which can directly filter aqueous solutions without pre-wetting. It is especially suitable for filtration of hydrofluoric acid, nitric acid, sulfuric acid, hydrochloric acid, other strong corrosive liquids, and organic solvents.
Key Features
- Excellent Corrosion Resistance: PVDF cage, core and end caps provide strong resistance to corrosive chemicals, making the cartridge suitable for harsh chemical filtration environments.
- Optional Hydrophilic PTFE Membrane: PLPVH Series uses hydrophilic PTFE membrane and can directly filter aqueous solutions without pre-wetting, helping simplify operation and improve process efficiency.
- High Temperature Resistance: The PVDF structure provides better high-temperature resistance than ordinary PP structure, with maximum operating temperature up to 130°C.
- High Filtration Efficiency: PTFE membrane provides high filtration efficiency and absolute-rated particle retention, helping remove fine impurity particles from corrosive chemical liquids.
- 100% Integrity Test Before Delivery: Each cartridge is integrity tested before shipment to ensure reliable sealing performance and stable filtration efficiency.

Product Advantages
Compared with ordinary PP filter cartridges, PLPV / PLPVH Series uses PVDF structural components, giving it stronger chemical resistance and better high-temperature performance.
The PTFE membrane provides excellent filtration accuracy and chemical compatibility, making the cartridge suitable for demanding corrosive chemical applications.
For aqueous corrosive liquids, PLPVH hydrophilic PTFE membrane can be used directly without pre-wetting. For strong solvents and highly corrosive chemical conditions, PLPV hydrophobic PTFE membrane provides stable and reliable filtration performance.
