In order to produce foam with the ST-160.2 a foam lance without air intake is absolutely required. The air quantity needed for foaming is supplied by an additional connection positioned at the injector. 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. Injector chemically resistant stainless steel 1.4305 / AISI 304. Injector with metering valve ST-161, compressed air connection and wall bracket. Inlet / outlet 1/2" F. Max. 350 bar / 90 °C
