Notes
You will need to know the flow rate and pressure of the pressure washer or system the injector is being fitted to.
- Select the closest flow rate (round up if needed).
- Move right across the chart to the nearest pressure column.
- The top number (e.g. 1.6) is the injector size.
For foam injectors not using compressed air, the number in brackets underneath is the correct ST75 foam lance size required.
