Oxygen concentrators are used to assist patients with respiratory illnesses or lung disease, who have diffculties in absorbing oxygen into the bloodstream.
An oxygen concentrator receives air, purifes it and then distributes the newly formed air. Typically, air is composed of 80 percent nitrogen and 20 percent oxygen. An oxygen concentrator increases the oxygen content to over 90 percent. Sieve bed flters contain Zeolite, which removes the nitrogen from the air.
Oxygen concentrators can be used in hospitals, home and some devices are portable.
Libra molecular sieves for medical oxygen applications include:
- 13X-L – Provides efficient performance for stationary and transportable concentrators
- LiX-L – Molecular sieve with high N2 removal capacity and selectivity to optimize performance for all concentrators, including portables
In a concentrator, air passes through a packed bed of molecular sieve where nitrogen is adsorbed, concentrating the 20% atmospheric oxygen to 90% or greater.
LiX-L is a lithium-exchanged molecular sieve that provides twice the nitrogen capacity of earlier adsorbents and permits the design of the smallest, most energy efficient units. This technology has enabled a new class of portable oxygen concentrators.
