Frequently Asked Questions (FAQ)

Q: What is the difference between hydrophobic and hydrophilic PTFE filters?
A: Hydrophobic PTFE membranes repel water and allow gas to pass, while hydrophilic versions wet out with water. For gas filtration, hydrophobic is essential to prevent moisture blockage.
Q: Can this cartridge be sterilized?
A: Yes, the PTFE membrane and polypropylene components can withstand autoclaving (121°C) or in-line steam sterilization (up to 135°C, upon request).
Q: What is the maximum flow rate for a 10-inch cartridge?
A: Flow rate depends on pressure and gas type. Typically, a 10-inch cartridge can handle up to 100 Nm³/h of air at 1 bar differential pressure. Contact us for specific sizing.
Q: Is the 1" NPT connection male or female?
A: Both options are available. Please specify your requirement when ordering.
Q: Do you provide integrity test certificates?
A: Yes, we can provide bubble point or water intrusion test reports upon request for each batch or individual cartridge.
Q: What is the typical shelf life?
A: Under proper storage conditions (dry, cool, away from UV), the cartridge can be stored for 3 years without performance degradation.
Q: Can I use this filter for liquid filtration?
A: This cartridge is designed for gas filtration. For liquid applications, we recommend our hydrophilic PTFE series.
Q: Do you offer custom lengths or end cap configurations?
A: Absolutely. We can customize cartridge length, end cap type (flat, dome, spear), and gasket material (EPDM, silicone, Viton). Contact our sales team.
