AXIVA – PTFE MEMBRANE FILTERS. Media – Polytetraflouro ethylene (Hydrophobic) with PP support. PTFE Disc Filters are chemically and biologically inert and stable up-to 260ºC and will with stand most concentrated acids and bases. Specific Features.

Hydrophobic membrane filters are typically used with compatible non-aqueous fluids. They are also commonly used as air, gas, or vent filters. Hydrophobic membrane filters are sometimes used with water or aqueous solutions; and, in these applications, they must first be prewet with a low surface tension, water miscible fluid prior to use.
