esPRO’s PF2 and HPF2-series PTFE membrane filter cartridges are designed for advanced filtration in both liquid and gas applications, offering exceptional chemical compatibility and durability in demanding environments. These cartridges feature a stable, high-performance PTFE membrane available in hydrophobic (PF2) and hydrophilic (HPF2) versions, ensuring optimal performance across a wide range of applications.

The PF2-series employs a hydrophobic PTFE membrane, making it ideal for gas and non-polar liquid filtration. It provides superior resistance to strong acids, bases, solvents, and other corrosive liquids while delivering a high flow rate with low pressure drop. The PF2-series is engineered for long-term reliability, even in the most challenging filtration conditions.

The HPF2-series, featuring a hydrophilic PTFE membrane, is specifically designed for aqueous solutions. It offers excellent hydrophilicity, low extractables, and high filtration efficiency, making it an ideal choice for processes requiring clean, efficient filtration without the need for pre-wetting.

Both the PF2 and HPF2 cartridges are constructed with ECTFE (ethylene chlorotrifluoroethylene) support and PVDF (polyvinylidene fluoride) end caps, cage, and core. This robust design provides excellent resistance to a wide range of chemicals, ensuring long service life and compatibility with aggressive chemical environments, withstanding temperatures up to 120°C.

Thanks to their high chemical compatibility and durable construction, the PF2 and HPF2 cartridges are ideal for critical applications where resistance to strong acids, bases, solvents, and heat is essential.
