EPT Series Hydrophobic PTFE Membrane Pleated Cartridges are constructed with high-quality naturally hydrophobic PTFE membrane as well as polypropylene support layers and components. PTFE membrane pleated cartridges provide better hydrophobicity compared to polypropylene pleated filters commonly used in compressed air filtration, making them ideally suited for gas/vent applications. PTFE membrane cartridges have wide chemical compatibility and excellent temperature endurance, thus being good filtering for less aggressive processes and high cleanliness applications.
