Open Supply Oxygen Concentrator Design | Electronics For You

With the second wave of covid-19 in India, the lethal virus has grow to be uncontrollable, infecting a bigger variety of folks than final 12 months. As a result of this, circumstances of sufferers affected by lack of oxygen have gone up. Sadly, it has grow to be very laborious to fulfill the rising demand, creating an enormous oxygen cylinder disaster.

However, getting ready oxygen cylinders and transporting them to an space prices loads of effort and time. Fortunately, a number of modern minds undertook this problem and designed an oxygen concentrator. The very best half is that it’s open supply and may be made with supplies which are straightforward to search out domestically.

RepRap, an organisation concerned in creating 3D printed elements for helpful applied sciences akin to robotics and management techniques has provide you with an oxygen concentrator design.

The compressed air is inserted inside a chamber on the backside. The air is cleaned and moisture eliminated with the assistance of silica gel. CO2 is eliminated with the assistance of activated carbon. Then the valves and chamber with zeolite take in the atmospheric nitrogen that separates the free oxygen. Afterwards, the air enriched with oxygen strikes to a continuing strain reservoir. With the assistance of a rehydrator, the moisture (that was initially eliminated by the silica gel) is restored. The opening and shutting instances of the valves are managed by an Arduino microcontroller and a MOSFET.
