A system for separating oxygen from air operates at a pressure less than atmospheric. The oxygen separation system includes an entry port for ambient air, and at least two separate exhaust ports through which separate exhaust streams are drawn by separate suction sources. The oxygen separation system further includes a low-energy ionization portion that favors creation of molecular oxygen ions, and a higher-energy portion disposed between the ionization portion and one of the exhaust ports. A plurality of gas-permeable electrodes are charged to different voltages to provide the different portions inside the separator. An exhaust stream taken from the anode side of the separator is enriched in oxygen relative to ambient air.

The system of claim 1, wherein the first electric field between the first and second electrodes is not greater than about 50 V/inch. 3. The system of claim 1, wherein the entry port is positioned closer to the first exhaust port than to the second exhaust port. 4. The system of claim 1, wherein the entry port is configured to cause expansion of entering gas sufficient for maintaining gas contained in the first container portion at a temperature below 20�� C. 5. The system of claim 1, further comprising at least one additional gas-permeable electrode disposed across the container and spaced a distance away from the third gas-permeable electrode. 6. The system of claim 1, further comprising a plurality of spaced-apart gas-permeable electrodes disposed across the container a distance downstream of the third electrode. 7. The system of claim 1, wherein the third electrode is maintained at a positive voltage substantially greater than a most positive one of the first and second electrodes. 8. The system of claim 7, wherein the electric field maintained between the third electrode and the most positive one of the first and second electrodes has a strength of at least 2000 V/in. 9. The system of claim 1, further comprising a voltage supply system connected to the first, second, and third electrodes, the voltage supply system configured to supply the second electrode with a more positive charge than the first electrode, and the third electrode with a more positive charge than the second electrode. 10.
