How to build a DIY zeolite oxygen concentrator?

To build a DIY zeolite oxygen concentrator, you would need to:

Obtain zeolite (such as 13X or LiX) for nitrogen adsorption.
Set up two pressurized containers filled with zeolite granules (the molecular sieves).
Attach a compressor to provide pressurized air.
Install valves to control airflow and manage the pressure swing adsorption (PSA) process.
Create an output system to channel oxygen-enriched air.
Ensure the system can alternate between pressurizing the zeolite beds and releasing nitrogen to regenerate them.
Due to safety risks, especially for medical oxygen use, this should be approached with caution, and professional systems are recommended for reliability.
