Feed Gas Differences

There are three types of feed gases used for ozone generation. They are ambient air, dry air, and concentrated oxygen.
Each of these are described below along with the advantages and disadvantages.

Ambient Air - Ambient Air refers to air from the environment whether it is located indoors or outdoors.

  • Advantages:
  • Free
  • Readily Available
  • Disadvantages:
  • Results in corona cell maintenance every few days, weeks, or months.
  • Can cause electrical component problems due to insects that can get lodged in the corona cell or corona plate.

Dry Air - Dry Air refers to air which has moisture removed so the dew point is -60 deg C or lower.

  • Advantages:
  • Allows a consistent ozone output over time.
  • Reduces corona cell maintenance (very important).
  • All dust and insects are removed.
  • Associated equipment is less expensive than concentrated oxygen.
  • Disadvantages:
  • Low concentrations result in low solubility in water.
  • More expensive than ambient air since equipment is required to remove moisture.
  • Still result in some nitric acid production.
  • Systems are more complex than using ambient air (need vacuum driven or pressure swing absorption air dryer).









The chart shows how ozone generator output decreases
as dew-point (moisture content) increases. Left axis
shows the relative output of the ozone generator.
(e.g. At -10 deg C dew-point, an ozone generator will
be producing 60% of its maximum {rated} output.)




Concentrated Oxygen - Concentrated Oxygen refers to oxygen which is of minimum 90% pure with moisture removed -100 deg F dew-point. It can be produced from an oxygen concentrator or delivered from an oxygen cylinder.

  • Advantages:
  • Allows a consistent ozone output over time.
  • Eliminates corona cell maintenance (very important).
  • Virtually all moisture is removed.
  • Ozone output is typically doubled (2x) vs. using dry air!
  • Highter concentrations means very soluble in water.
  • Disadvantages:
  • More expensive than dry air systems since more equipment is required.
  • Systems are more complex than using dry air (need compressor and oxygen concentrator).












The picture to the right shows that Oxygen Concentrators
generate 90% O2, 5% Argon & 5% Nitrogen
