Honeywell UOP developed the first commercially viable adsorbent for medical oxygen applications more than 40 years ago. Today, UOP’s OXYSIV™ molecular sieve adsorbents help make smaller and more energy efficient medical oxygen concentrators to meet patient needs more effectively.

UOP molecular sieves for medical oxygen applications include:

• OXYSIV 5XP – Provides efficient performance for stationary and transportable concentrators
• OXYSIV MDX – 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 OXYSIV where nitrogen is adsorbed, concentrating the 20% atmospheric oxygen to 90% or greater.

MDX 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.
