PF4/HPF4 series - Membrane Cartridge Filters Cartridge Filter Hydrophilic 69

esPRO’s PF4 and HPF4-series filter cartridges are the ideal solution for the most aggressive chemical applications. These all-Teflon® filters are engineered to provide superior chemical compatibility, making them perfect for filtering highly corrosive liquids such as strong acids, bases, and oxidants. The PF4/HPF4 series is specifically designed to maintain the highest level of cleanliness, effectively reducing metals, chlorides, and other contaminants.

The PF4-series features a hydrophobic PTFE membrane, while the HPF4-series incorporates a hydrophilic PTFE membrane, offering compatibility with both liquid and gas applications. These filters deliver exceptional flow rates and a long service life, even in the most demanding environments.

Constructed with PFA (perfluoroalkoxy alkane) for the support, end caps, cage, and core, the PF4/HPF4 cartridges provide unmatched chemical resistance, ensuring structural integrity in extreme conditions. With a maximum operating temperature of 180ºC, these filters are built to perform reliably in high-temperature chemical processes.

The PF4 and HPF4-series are the top choice for industries that require the highest level of chemical compatibility and cleanliness in aggressive environments, making them the preferred solution for critical filtration processes.
