01Flow rounds up

As specified by the supplied chart, the calculator rounds your flow up to the next available LPM row.

02Pressure uses the closest column

Your working pressure is matched to the nearest pressure value contained in the sizing chart.

03Use a chemical filter

A filter helps prevent debris entering the injector. Chemical viscosity can also affect the draw rate.

Technical note

Foam performance also depends on the matching foam head, hose restrictions, chemical viscosity and system condition. Confirm unusual or critical installations with Lanceman.
