Teflex Series

Summary

Product Identification

The Industrial Teflex Series consists of BETA 5000/Absolute-rated PTFE Membrane Cartridges designed for applications requiring polytetrafluoroethylene (PTFE) membrane cartridges. These cartridges combine polypropylene with PTFE and feature polypropylene endcaps, center cores, and outer support cages for durability.

Key features include:

• PTFE membrane for full particle retention.
• Reduces particles as small as 0.1 micron in size by mechanical means*.
• Efficiency rating exceeds 99.98% (beta 5000).
• Polypropylene center core and outer support cage for increased durability.
• Manufactured from FDA-listed materials.
• Meets USP Class IV biological test for plastics.
• Multiple endcap configurations and O-ring materials available.

* Not intended for the removal of microbial pests including virus, bacteria and cysts.
