ST164 INJECTOR WITHOUT COMPRESSED AIR MODULE-2.4mm
Description
The ST164 chemical Injector made from stainless steel, designed to be part of a cleaning system to produce foam. This injector has an optional compressed air connection and allows the user to have up to two different chemical options attached. The different chemicals can be selected by positioning the lever.

Overview
RM Suttner ST164 Foam Injector
This venturi foam injector has a restrictive orifice that the water stream is forced through. Operating this injector with a device that contains a low pressure nozzle such as a Suttner ST75 foam lance causes a vacuum effect within the foam injector, chemical is then drawn up into the water stream. 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. The ST164 allows the user to select between two different chemicals by simply positioning the lever. Suitable for systems used to clean vehicles carrying cattle and food processing areas to avoid bacterial spread. We have a range of equipment that can be used in combination with our injectors to apply foam. The ST75 Foam Head, ST76 Foam Blaster or our extremely innovative Triple Nozzle which is specifically designed for applying foam and disinfectant chemicals within food processing environments.
For those requiring a dryer more sticky foam this injector has an optional compressed air connection. A DN12 hose must be used with a 1/2" inlet and outlet wash gun to stop the foam collapsing.
The ST164 chemical injector is available in nozzle sizes of 1.2 - 2.8mm.
G&S have a range of equipment dedicated to cleaning food processing environments. Take a look at our Food Industry page for more information.
Nozzle Sizing
In order for the foam 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 nozzle 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.
Â
Chemical suction is affected by water temperature
At higher temperatures the maximum achievable vacuum drops significantly. The graph demonstrates that at temperatures of 90°C and above, the venturi effect becomes impossible.Â

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