a. PSA oxygen concentrator. The lower oxygen concentration of PSA oxygen concentrator will lead to low ozone concentration.
b. Ozone tube. The accuracy of ozone tube will affect ozone discharge, resulting in uneven discharge and low utilization rate of oxygen. It may also lead to lower ozone concentration.
c. Electronic board. Electronic board is the key supplyment to ozone tube. If they do not match, ozone generator could not attain its perfect working state.
