Oxygen Fed Ozone Generators versus Ambient Air Fed Generators – Which technology is right for you?

Corona discharge ozone generators typically fall into the two categories ( based on the feed gas used to generate the ozone). While some require purified oxygen, others claim to be able to operate using an ambient air feed. What are the main differences between the two and which one is the right choice for you?

Oxygen Fed Ozone Generators:

Oxygen fed ozone generators typically require an additional component called the oxygen concentrator.

Pressure Swing Adsorption (PSA) – The typical layout of the PSA Oxygen Concentrator.

In order to yield the higher volume ozone output typically required for the industrial ozone applications, your ozone generator must be designed to accept a gas feed containing a significantly higher concentration of oxygen than what is readily available om the ambient air.

Since the typical composition of ambient air is 21% oxygen and 78% nitrogen, the most economical way to increase the concentration of oxygen in ambient air is to remove the nitrogen component from it.
