    The process of Oxygen Concentration

    As mentioned before, the main function of the replacement columns is to convert normal into high oxygen concentration air. For this cause, the sieve beds are responsible for filtering out the nitrogen which is coming with the air into the concentrator. After passing the second filter, the air gets concentrated into oxygen.

    However, this is where you can spot the importance of the sieve beds. If the sieve beds are not functioning properly, the oxygen coming through will be less pure, simultaneously not enough nitrogen will be removed.

    As a consequence, patients who require special care because of their disease (especially if the disease affects the lungs) may not get their oxygen dosage. The final result is that a patient may not get their therapy due to malfunctioning of the sieve beds.
