The most efficient and durable foam injector available, with a dilution range from 12:1 to 200:1. The easiest way to select between two chemicals and rinse. Simply switch lever on the top of the injector to the desired position(chem 1 or chem 2) and let the soap fly.
Metering tips control the soap's draw rate. The dosing nozzles have a pin sized hole the soap is drawn though, the size of this hole determines your soap to water ratio. Suttner foaming Injectors arrive with the correct dosing nozzles already installed. The dosing nozzles offer a dilution range from 12:1 to 200:1.
Change between rinse and foam directly at the gun. Simply release trigger and twist The Suttner ST-58 Change Over Valve to either rinse or foam. The Chem-X Foam Lance screams quality and durability.

-Injector will be set to run at 100:1 unless specified otherwise, this can be changed by simply changing metering tip inside injector barbs.
-If using a hot water machine, scale build up can clog the foam nozzle on the lance. On start up always run lance in rinse mode for about 30-60 seconds to flush out any debris through the rinse nozzle. For systems that see frequent clogs due to coil scale/debris we offer this ST-75 Foam Nozzle which is less likely to clog and can be rinsed.
Use the chart below to figure out your nozzle size. You will need your power washer's current GPM and PSI. This information is usually found on a sticker located on your machine.
