Injector ST-167 without compressed air

The injectors completely made out of stainless steel make it possible to open two cross section areas (50 mm2 each) in order to guarantee a smooth use without drop in pressure when washing/rinsing. This ensures that the injector can be permanently kept in the high pressure line, also at the time when large water quantities are used e.g. in the agriculture or food industry. The cleaning capacity when cleaning and rinsing is not affected at all. A lever makes it possible to change from the cleaning and rinsing mode into injector operation. When using the cleaning mode, there are two bore holes guiding the high pressure water parallel to the injector (bypass mode). When using the injector the available water quantity is guided through the injection area.

In combination with a foam lance (ST-72, ST-74 oder ST-75), an adjustable or a triple nozzle the easyfoam365+ injector ST-167 can suck in chemicals by means of the integrated check valve made out of stainless steel. It de-pends on the chosen nozzle whether the chemical can also be sprayed on or foamed. The foaming covers large areas and a long expo-sure time is guaranteed. One further advantage of the foam cleaning is that already covered surfaces are easily seen.

The easyfoam365+ injector which is available in the nozzle size of 1.2 - 2.8 mm meets the requirements in every field of application in the professional cleaning industry. The dosing is adjusted by one of the 10 nozzle inserts which are included in the consignment. As an alternative there are also versions with the infinitely variable dosing unit ST-161 available.

The connection for chemicals equipped with an integrated check valve and an intake for the nozzle inserts has a hose tail for chemical suction hoses being 9 mm in diameter in order to suck in especially viscous fluids. The direction of flow is marked with arrows to guarantee a smooth installation.

Choosing the suitable nozzle is most important for output and smooth function of the high pressure cleaner:

Nozzle too

small = machine permanently switches into bypass or off.
wide = machine has a small output, lower pressure.

How to choose the suitable nozzle?
Attention: pressure and flow of the high pressure cleaner must be known e.g. 15 l/min (900 l/h) - working pressure of 150 bar.
