The change-over lance ST-175 Foam & Clean is the ideal accessory for Suttner’s foam injection line. The innovative change-over technology allows to direct the full flow into either one or the other outlet pipe just by turning the hand wheel at the inlet. In one position of the hand wheel the flow is directed through an ST-75 foam head for foaming. After changing over the full flow is directed through the other pipe and a regular spray nozzle for rinsing.
Appropriate nozzle sizing at chemical injector and ST-175 allows changing from foaming to rinsing right at the lance. ST-175 Foam & Clean is compatible to ST-160, ST-164, ST-166 and ST-176. Due to ST-175’s changeable air injector nozzles the lance can be driven with all pressure washers with flow rates from 5 to 25 l/min. Nozzles with integrated jet foamer are required.
