An oxygen generator, or O2 generator, sometimes called an oxygen machine or an oxygen generator, sucks the ambient air that one breathes and removes or scrubs on the nitrogen atom , leaving the other gases present in the air, most of which are very oxygen concentrated. Some O2 recreation generators produce about 30% purity of oxygen. Visit for more about oxygen generators.

The key to most of these O2 machines and this oxygen separation technology is a mineral called zeolite

Most regions of the earth are composed of 78% nitrogen and 21% oxygen. When the oxygen generator is activated, the air is drawn through the zeolite "seedbed filters" of the machine, and the zeolite adsorbs the nitrogen. This is another way of saying that the nitrogen glue to the zeolite. The oxygen generator then "cycles" the nitrogen out, and once to remove the nitrogen, the oxygen is pushed out if the "nozzle out" (as well as some other inert gases) and is typically blown through a cannula fixed nasal, AKA pipe nose or other respiratory connection, such as a nose or mask.

Visualizing the process could make it clearer

The oxygen generator has an integrated air compressor. It sucks the air and then compresses the normal pressure a few times. The zeolite absorbs nitrogen under this increased pressure. Now a valve opens and the remaining gases, which are mostly oxygen and some water vapor, flow into the next chamber. This room is connected to the outlet of the pipe and provides us with concentrated oxygen. At the same time, another valve opens and the residual gas, which is mainly nitrogen, is allowed to vent safely into the ambient air. This process is repeated many times, creating a constant flow of enriched and pure oxygen. Some oxygen generators use oxygen machines or oxygen generators that can produce a current of 5 and / or 10 liters of oxygen per minute. Some portable oxygen generators use an on demand arrangement. They store oxygen in a tank that is machine-resident, and then it releases the O2 only when you inhale. These devices are called pulse oxygen generators. Oxygen generators use continuous oxygen flow concentrating machines (oxygen generators) that produce a steady flow of 5 or 10 liters of oxygen per minute, depending on the machine used.
