An experimental study on modification of oxygen concentrator components for better purity

During the covid time, it was observed that the need for oxygen was very high, and this need was not achieved just by the oxygen cylinder. Ordinary people and hospitals started using oxygen concentrators to meet these needs. This paper focuses on improving the purity and the output flow rate of the oxygen concentrator. Different modifications were made by varying the number of air pores and filter count. Also, the compressor parameters like bore size, length, and flapper counts have been modified to increase the airflow concerning a liter per minute (LPM). The solenoid valve was configured to give maximum efficiency. Following the process, different Zeolite combinations were used to find the optimum purity of the oxygen concentrator. These modifications to the concentrator setup enabled 91.3% pure oxygen generation with an increase in the flow rate of the concentrator by 20%.
