Abstract: A water tank is connected through a pump and a valve to an inductor container which in turn is connected through a valve to a foam holding tank which is pressurized by it being connected to an air compressor for delivering foam to an outlet for providing a foam guideline on the ground. The valves into and out of the inductor container are first closed and then the inductor container is filled with liquid foam. The valves are then opened and water under pressure is delivered to the inductor container where it is mixed with the foam and then delivered into the foam holding tank. The valves are again closed and a drain valve on the inductor container is opened to removed water from the inductor container in preparation for the next filling cycle.
