Parts to build a 90+% pure oxygen concentrator @ 10-15L per minute, depending on pump. It follows the open source Oxikit project documentation. Videos/documentation provided below.
All parts to complete the Oxikit Concentrator is included EXCEPT: pump ($250-400), Arduino/MEGA32 type microcontrollers ($10-20), Arduino shield ($10-20), and fabricated mounts to mount it all together. Sieve beds are partially assembled.
I am selling to move on to other projects and reprioritizing my time.
Oxygen generators are useful for glassblowing projects where extremely high torch temperatures are required. For this purpose a flame arrester (not included) is required for safety. They also can be used for other projects or experiments where oxygen is desired. NOT FOR MEDICAL USE.
Open to offers. May or may not be persuaded to complete project for you. No trades/barter. Willing to travel/deliver (depending on location).
