Foam Nozzle Size Chart

Find your machine’s flow rate down the left and its working pressure across the top. Where they meet is the injector size to fit.

Foam injector size guide

Rows are flow in litres per minute, columns are working pressure in bar. The large number is the injector size; the number in brackets is the matching ST75 foam lance size.

A blank cell means that combination falls outside this chart — call us and we will work it out with you.

Notes

For foam injectors not using compressed air, the number in brackets is the correct ST75 foam lance size required.
