Ozone Injector Comparison

1. No pump being used:
   Select an injector that will meet your known inlet & outlet PSI’s, but still provided an adequate Air Suction value. Always make sure that the Motive Flow GPM value in the injector chart is less than the expected output GPM Flow rate of your application.
2. Using a pump which has no existing line pressure City pressure against it: Using the pressure curve chart for the pump, select on the graph the appropriate values (PSI head at GPM Flow) Then match those determined values to a selected injector (Inlet PSI and Motive Flow GPM). Always make sure that the Motive Flow GPM value in the injector chart is less than the expected output GPM Flow rate of your application.
3. Using a pump which has existing line pressure City pressure against it: Use the instructions for #2 and add to the mark selected on the pump curve chart the incoming pressure which feeds the pump.

NOTE - Accounting for your expected injector Outlet pressure (or downstream pressure), choose an injector that provides the optimal Air Suction SCFH for your application using the appropriate instructions above. Pump wear can result in lower pump performance over time, or if the suction flow is initially too high it can always be regulated down with a valve.
