Separating compressed air with Prism Membrane separators generates two gas streams: nitrogen and oxygen enriched air (OEA). The more commonly desired gas is the nitrogen stream, but in many cases, our customers desire the oxygen enriched air stream as their product gas. Common OEA applications include nitrox (scuba dive gas), water treatment, enhanced combustion, and oxygen-enriched breathing air at high altitudes.
This data sheet provides two different performance tables for OEA generation at different pressure settings. For oxygen purities of 25 percent to 40 percent, we recommend our membrane products with N1 fiber type inside. On the other hand, for applications that require the oxygen purity to be between 40 percent and 50 percent, we recommend our P3 fiber type to reduce the amount of feed air required.
