Frequently Asked Questions (FAQ)
-
Q: What is the absolute filtration rating of this cartridge?
A: The cartridge has an absolute pore size of 0.2 μm, meaning it effectively removes particles larger than 0.2 microns, including bacteria and fine particulates. -
Q: Can this cartridge be used for high-temperature liquids?
A: Yes, the PTFE membrane can withstand temperatures up to 260°C (500°F), making it suitable for hot liquids and gases. -
Q: Is the 222 O-Ring compatible with standard housings?
A: The 222 O-Ring end cap is a common industry standard and fits most 10-inch filter housings designed for 222 O-rings. We also offer other O-ring sizes upon request. -
Q: What O-ring materials are available?
A: Standard options include EPDM, FPM (Viton), and silicone. Other materials like PTFE encapsulated O-rings can be customized for specific chemical compatibility. -
Q: How do I know the filter is clean and ready to use?
A: Each cartridge is individually wrapped and packed in a clean environment. For high-purity applications, we recommend a pre-wetting and integrity test per your protocol. -
Q: Can this filter be used for sterile filtration?
A: Yes, the 0.2 μm rating is suitable for sterilizing-grade filtration. However, final validation should be performed by the user for their specific process. -
Q: What is the typical flow rate for water?
A: Under standard conditions (1 bar differential pressure, 25°C), the flow rate for water is approximately 30-50 L/min per 10-inch cartridge, depending on housing design. -
