Technical parameters

Working principle

This system contains units of foam tank, vacuum type porportioner (in-line inductor), fire hose, foam gun and control valves. Pressurized water will flow through a narrow part when it flows into proportioner. There is a pipe at the narrow part which was connected with foam tank. For the flow velocity at the narrow part is bigger than other parts that its pressure gets smaller than standard atmosphere, resulting in vacuum at outlet. Thus the foam concentrate was absorbed out and conveyed to foam generator. The tank has two outlets to choose from or used at the same time.
