Ox01d: Oxygenator connected to face mask

We have deviced a new single column setup optimized for high oxygen concentration. The next goal for Ox01d is to make it even simpler, getting rid of Arduino maybe and using cheaper valves with same output.

  • 1: 3-way valve
  • 2: needle valve
  • 3: Mass flow controller
  • 4: needle valve
  • Zeolite bed: 750 g LiX
  • Feed: 5 bar from compressor with pressurized air filter
  • Simple bubbler + bacterial filter
  • Snorkelling face mask

Parameters&Performance

  • Production: 5-6 l/min with 40% oxygen, about 70% relative humidity
  • Cycling: 4 s pressurize 4 s depressurize
