PTFE membranes for ventilators

Suitable for filtering variety of liquids and gases, microporous PTFE membranes are used in many of the medical, laboratory and industrial instruments. Typical applications include particle filtration, venting and diffusion barriers, and specifically for medical equipment, microporous membranes are effective filtering medium used in ventilators’ oxygen sensors.

The most popular technology for measuring oxygen concentration in air, oxygen sensors work as a result of a chemical reaction. Voltage is generated in this process, and the rate of voltage indicates oxygen level. With potassium hydroxide (KOH) used typically as an electrolyte, chemical resistance of filtering media is very high on the list of requirements.

With micro pores between 1 and 6 microns, Saint-Gobain Zitex PTFE membranes are chemically inert and thermally stable in aggressive environments. They able to handle virtually any corrosive fluid at temperatures as high as 500oF (260oC) and as low as the cryogenic range of -450oF (-268oC).

Supplied as customized die-cut pieces for convenience, Zitex PTFE membranes are a filtering medium of choice for ventilators used to combat rapid spread of Covid-19.
