Even though we sell the Synergy systems ozonators on our website, I have never seen a chart for them. I personally feel that the output control knob is somewhat unreliable for determining ozone output with any particular oxygen flow. I recommend that people use the knob at full except for air purification purposes which may require lower concentrations.
Do you have the Synergy single or double cell unit? That would make a huge difference in the answer you seek. If it's double cell unit, you would be getting approx 25-32 gamma from one cell only with the knob at full and at a flow of 1/4 lpm. It would be the same from a single cell Synergy unit. Your question would be best answered by the manufacturer, John Copley at 615-337-8611.
hope this helps,
