Used rack-mount ozone generators for sale.  Produces 40+ g/hr of ozone from oxygen. 
Air-cooled ozone.
Operates on 120 VAC power, cord included.

We purchased this ozone generator as part of a larger decommissioned ozone system. 
We tested this ozone generator in our shop with a UV ozone analyzer and found the following performance data:

This ozone generator should produce ozone well on either oxygen or dry air.  Due to construction we would suggest limiting operating pressure to 5 PSI or below.

We obtained three of these ozone generators.  We have two listed for sale, and have one for parts.  The unit for parts has many functional parts but was robbed of a few cells to repair leaks on the functional units.  If a customer wanted a long-term low cost option would be to purchase both units we would then give the spare unit to them for parts.  This could provide a long-term ozone production solution at a minimal cost.


One note about this ozone generator, due to construction with the tube style it does produce a bit of fugitive ozone in the air.  There are no ozone leaks, but a small amount of ozone is produced external to the cell due to stray voltages in the center of the conical tube style ozone generator dielectrics.  Due to this, ensure operation of these devices is a well ventilated room (12 air exchanges per hour) or operate in a room larger than 2,000 square feet.
