How is zeolite powder for oxygen concentrator used?

Zeolite powder for oxygen concentrators is typically not used in its powdered form but as granules or beads. Granules provide the necessary structure and surface area for effective gas adsorption. If zeolite powder were used, it could lead to clogging or reduced airflow within the concentrator, impairing performance. The granular form ensures proper air passage and efficient separation of nitrogen from oxygen.
