Our membranes can be used to generate oxygen enriched air streams with o2 purity of up to 50%. On that note,  we have experienced an increase in OEA interest recently and wanted to remind everybody of the safety precautions of working with oxygen or oxygen enriched air. Here’s a great document that covers oxygen specific safety tips like:
• Keep non-typical ignition sources in mind when designing systems for oxygen use.

• In an oxygen-enriched environment, fire chemistry starts to change and materials become easier to ignite.

• Clothes can trap and hold the oxygen enriched atmosphere in the countless air spaces within the weave of the fabric. Hair poses the same problem.

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.
