The Medium Expansion Foam Generator unit consists of a stainless steel casing, a fan driven by a pelton wheel turbine, four jet nozzles to discharge foam water solution in front of high velocity air, an in line inductor for foam suction and a nylon foam-making net.
Design and Operational Features:
Water from the fire hydrant engine is pumped into the generator through an in line inductor, placed along the supply line. Foam concentrate and water are mixed in the inductor to make foam water solution, which is delivered to the generator. Part of the water supplied is diverted, to drive the pelton wheel turbine. Through the four water jets, foam water solution is sprayed in to the foam- making net to produce foam.Can also be used us a smoke extractor.
The unit produces high expansion foam up to 100m (3500ft) PER minute, depending upon the pressure applied. The foam generated is more fluid and heavy, therefore ideal for outdoor fuel spillage or where rapid, flowing foam is required.
The unit comes with polythene foam ducting, 30 m and reinforced plastic smoke ducting,7.5 m. These are optional and not part of standard equipment.
