GGPTFE

Summary

Product identification

The GGPTFE-Series High Purity General Grade PTFE Filter Cartridges utilize an expanded polytetrafluoroethylene (PTFE) membrane, offering superior chemical resistance across a broad range of industrial applications. They provide consistent contaminant removal in aggressive fluids and organic solvents, with retention ratings as fine as 0.1 µ (100 nanometers).

For air/gas/vent applications, the single-layer PTFE membrane delivers superior hydrophobicity compared to polypropylene or PVDF, helping to prevent water wetting and diminished flow. Cartridges are manufactured in a clean-room environment to maintain high standards of purity and cleanliness.
