ST164 INJECTOR WITH DOUBLE CHECK AIR MODULE Field of application: Designed for the cleaning of vehicles carrying cattle, food, frozen foods and fish in order to avoid bacterial spread. Also suitable for cleaning milking parlours and applicable in cattle bredding, piggery, poultry farming and in the pisciculture. The foam device is a combination made out of stainless steel and special high performance plastics. The addition of one out of two connected chemicals is determined by positioning the lever. All versions are suitable for the addition in low pressure from approx. 5 bar up to max. 350 bar. When being operated in rinsing function up to 60 l/min pass through the unit without any drop in pressure. In combination with a foam lance (ST-72, ST-74 or ST-75), an adjustable or a triple nozzle the ST-164 injector can suck in chemicals by means of the integrated check valve made out of stainless steel and spray them on or foam them depending on the chosen nozzle. The injector has an optional compressed air connection in order to supply the required air quantity for foaming already in the injector unit. For the application of foam a foam lance without air intake is absolutely required. The use of a spray gun with large cross section areas such as for example ST-2720, ST-2725, ST-3100 or ST-3300 with suitable lances and foam hoses (blufood) is recommended. The injector is especially designed for low and medium pressure applications from a water inlet pressure of 5 bar and it generates an excellent foam when being provided with the required quantity of compressed air. The ST-164 injector is available in the nozzle size of 1.2 - 2.8 mm. The dosing is adjusted by one of the 10 nozzle inserts which are included. The connection for chemicals is equipped with an integrated check valve.
