Indian researchers have designed a robust, mobile group oxygen concentrator called Oxyjani.
About
OxyJani is based on the principles of Pressure Swing Adsorption (PSA) technology.
The team replaced lithium zeolites (LiX) which is usually used in oxygen concentrators, with sodium zeolites which does not generate toxic solid waste and can be manufactured in India.
The concentrator is capable of delivering a range of solutions, conversion of medical air to medical oxygen, and is an entirely off-grid solution including all modules that can facilitate deployment in rural areas.
Moreover, the waste from the 13X zeolite plant can be potentially a good agricultural input material.
This new class of technology called “group concentrators” has the robustness of large PSA plants, portability similar to the personal concentrators, and is affordable too.
The device is in the range of 30-40 litres per minute (l/min)., which is potentially useful for ICU uses too.
