Our first operational prototype using only a tube filled with zeolite, a manual three way valve and an oxygen storage container.
Schematics

- 1: manual 3-way valve
- Zeolite bed: 30g in plastic tube
- Feed: 5 bar dry air
Parameters&Performance
- 30 g of Zeolite LiX in Reverse Osmosis Membrane housing
- Feed: 5 bar compressed dry air
- Production: ca. 1 l/min with 80% oxygen
Hello thank you for sharing, we would like to re-produce this manual prototype, however the schematic is showing 2 vales 1&2 though the BOM states 1x manual 3 way valve.. can we deduce that there is no need to close off the O2 exit line when switching to exhaust ?? Would appreciate a more step wise tutorial on a system setup..
