Overview

RM Suttner ST168 Foam injector with compressed air module.

This ST168 foam injector has a compressed air module and can be used with both high and low pressure devices to produce foam, this injector can also be operated using water line pressure (5 bar).  The lever on the injector makes it possible to easily change from chemical to rinse mode, a foam lance without air intake can be used with this Injector to produce foam.

These injectors are used in many industries for industrial cleaning including Agriculture, Automotive and the Food processing industry. This is an essential piece of equipment for anyone looking to design and build an efficient cleaning system within a factory environment. Suitable for systems used to clean vehicles carrying cattle and food processing areas to avoid bacterial spread.

A DN12 hose must be used with a 1/2" inlet and outlet wash gun to stop the foam collapsing when using compressed air.

The ST168 easyfoam365+ chemical injector is available in nozzle sizes of 1.2 - 2.8mm. Chemical dosing can be adjusted by one of the ten included nozzle inserts.

 

Foam Application

When applying foam to vertical surfaces it is important to start from the bottom and move upwards. If foam is applied from top to bottom you will get overlap, increasing the foam mass and reducing its contact time with the surface you are working on.

Which chemical injector nozzle size do I need?

In order for the chemical injector to add chemical to the water stream the pressure being exerted through the injector needs to be lowered. It is important to get the correct injector size combined with foam nozzle size. The larger the hole where the water flow exits the lower the pressure becomes. The higher the water flow of the system the injector is operating on the larger the nozzle hole needs to be. This ensures the pressure is kept low enough to create the vacuum effect required to add chemical to the water stream. If you know the flow and pressure of the system your injector will be working on you can use our interactive chart below to ensure you select the correct products.

We highly recommend using a chemical filter on the end of your chemical tube. This helps to prevent any unwanted debris possibly entering your chemical injector and causing a blockage. Always check the viscosity of the chemical you are using as this can greatly affect the draw rate of the chemical into the water stream. Dosing of chemical can be adjusted by adding one of the ten nozzles inserts which are provided with each injector.

 

Help with sizes

Use the below chart to help you select the correct injector size.

Using the chart

You will need to know the flow rate and pressure of the pressure washer or system that the injector is to be installed.

Firstly select the closest flow rate (round up if required)

Then move right across the chart until you are at the closest pressure column.

The top number (1.6) is the injector size.

The number in brackets underneath is the recommended ST75 foam lance required.
