A main tank of a foamable soap and water mixture is fluidly connected to a manifold positioned on top of the tank. A pair of air tanks are fluidly connected to the manifold as well and are also mounted on the tank. Within the manifold the foamable fluid of the tank and the gas of the air tanks is mixed in a manner such that the gas is parallel to the flow of the fluid through the manifold thereby precluding a damming effect of the fluid by the air. This foams the foamable fluid which is then passed to a conventional fire hose for dispersement therethrough.
