Less Wasteful Air Separator

The only Air Separator allowed by environmentalists

• Produces O2 and/or N2 as long as there is any consumption of either or both gases.
• Stops production to save energy if both gases back up.

Usage

• Take O2 and/or N2 from the balancers on the sides. Do not take from the tanks.

Design

• Loops both gases around through individual overflow vents, then blending them strictly 1:1, and then subsequently with the air separator's output (with priority).
• If both gases back up the strict 1:1 mixture will block the air separator's output, thus stopping it until consumption is restored.
• If consumption is uneven, the surplus gas will vent its overflow.

*Engineers are still trying to explain how re-blending the separated air can help conserve energy (or, since tanks can separate N2 and O2, why anyone would need an air separator in the first place).
