ST-167
General
These fully stainless steel ST-167 / ST-168 injectors pro vide
the option of enabling two larger cross-sections in order to
guarantee virtually no pressure drop in flush mode. This makes it
possible when using large volumes of water to leave the injector
permanently on the high pressure line without adversely affecting
cleaning performance in cleaning and flush modes. A selector
enables switching between injector and flush mode, whereby two
holes duct the water parallel to the injector (bypass operation)
and injector operation, where the volume of water available is
ducted through the injection area.
With the ST-167 chemicals can be drawn in when used in
combination with a foam lance such as for example the ST-72,
ST-74 or ST-75 or a surge regulator or multi-regulator nozzle and
be sprayed or foamed using the nozzle selected.

ST-168
With the ST-168 no active, i.e. separate, air intake foam lance
is necessary to generate the foam. The volume of air needed
for foaming is fed via an additional connector on the injector.
Use of a large cross-section spraygun such as for example the
ST-2720, ST-2725, ST-3100 or ST-3300 with suitable lances and
foam hoses such as the "blufood" is recommended. The ST-168
is particularly suitable for use at low or medium pressure from
5 bar upward of water intake pressure and generates excellent
foam given the appropriate compressed air supply.
The injector operates with a maximum inlet pressure of 350
bar and due to the use of high-quality materials can be used at
temperatures up to 100 °C. Throughput direction is indicated with
arrows to ensure ease of installation.
