1. System Purpose & Operational Context
At elevations around 5000 m—where barometric pressure is approximately half that at sea level—the partial pressure of oxygen drops enough to induce hypobaric hypoxia, leading to acute mountain sickness, impaired cognition, and cardiovascular strain. The Neometrix Oxygen Enrichment Facility (OEF) addresses these challenges by raising indoor oxygen concentration from 21% (ambient) to 27–30%, simulating a much lower equivalent altitude. Deployed in research outposts, military encampments, medical tents, and acclimatization shelters, the OEF ensures personnel maintain optimal physiological function during prolonged high-altitude exposure.

2. Core Technology: PSA Oxygen Generation
 • Dual-Column PSA Towers: Two parallel adsorption columns packed with lithium-exchanged zeolite alternately adsorb nitrogen and regenerate, providing a continuous oxygen stream.
 • Molecular Sieve Design: High-performance sieves deliver >93% purity oxygen in the 80 LPM model, while 40% purity in the 130 LPM and 230 LPM models is blended into room air for energy efficiency.
