How to choose the materials for gas filters?

Gas filters are generally made from hydrophobic materials, such as PTFE and PVDF.

Is gas filtration precision the same as liquid filtration precision?

Because the filtration mechanisms differ between gases and liquids, gas filtration generally removes smaller particulate contaminants, so gas filtration precision is relatively higher than that of liquid filtration.

How to prevent premature clogging of gas filters?

1. Select appropriate filter materials and pore sizes based on product compatibility and impurity profile.
2. Adding a pre-filtration step to remove large particulates and extend the service life of the final sterilizing-grade filter.
3. Design and control the process to prevent premature filter wetting.

How to perform integrity testing for gas filters?

For most gas filters, water intrusion can be used for integrity testing. For gas filters with smaller surface areas or low water intrusion flow rates, organic solvents may also be used for wetting to conduct bubble point or difffusion flow tests.

What are the advantages and benefits of Cobetter gas filters?

1. A variety of materials to meet specific process requirements are available.
2. Different filtration precision configurations, such as single-layer, double-layer, and multi-layer setups, can enhance filtration flux and extended service life.
3. Hydrophobic and oleophobic properties improve resistance to clogging.
4. Strong chemical compatibility and high-temperature resistance.
