Reverse Engineering Based PSA Chemical Oxygen Concentrators Design

There is an increasing need for portable respirators due to the Corona pandemic, and these devices need small size and low cost oxygen concentrators. This paper aims to use reverse engineering concepts in the design and implementation of a portable oxygen concentrator to assist respiratory patients. It also deals with the study of the properties of chemicals suitable for use in the proposed device. Practical tests of the device showed its ability to produce 10 liters per minute with a purity of 98% oxygen. The engineering style of the device is low cost, compact and can be easily used in homes, ambulances and work sites.
