Product Description

Hydrophobic (water-repellent) ePTFE (expanded polytetrafluoroethylene) membrane filters (disc-shaped) have good particle capture performance due to their three-dimensional porous structure, and are resistant to chemicals and biological organisms. They are suitable for blocking aqueous liquids and allowing gas to pass through the membrane. The specifications are as shown in the table below.

*1. The bubble point mentioned here is the minimum pressure required for air to pass through a membrane pre-wetted with isopropyl alcohol (IPA).

*2. IPA flow rate measured at a differential pressure of 40 kPa.

  • Membrane distillation
  • Gas Filtration / Liquid Filtration

  1. Burning PTFE can produce toxic gases, so do not burn the membrane.
  2. The user must fully understand the properties of the material before using it and must assume all risks arising from its direct or indirect use.
