What type of zeolite is used in oxygen concentrators?

The most commonly used zeolites in oxygen concentrators are synthetic types like Zeolite 13X and Lithium-exchanged Zeolite (LiX). Zeolite 13X is an aluminosilicate with a specific pore size that efficiently adsorbs nitrogen molecules. Lithium-exchanged zeolites replace some of the sodium ions in the zeolite structure with lithium ions, enhancing the material’s nitrogen adsorption capacity. These zeolites are chosen for their high selectivity, thermal stability, and mechanical strength, making them ideal for the rigorous demands of continuous oxygen generation in concentrators used for medical or industrial purposes.
