This setup features an industrial screw compressor that provides air at 12 bar pressure to a membrane, which separates nitrogen and oxygen, achieving up to 40% oxygen. The oxygen-enriched air can then be compressed to 232 bar when paired with a high-pressure compressor. The oxygen concentration at the output can be adjusted between 22.4% and 40% using a valve located on top of the compressor. An oxygen analyzer is included to ensure the correct oxygen level and to make any necessary adjustments using the designated valve.
