A fire suppression system may include a tank and a manifold that may be inside or outside the tank. The tank, when charged, holds a liquid and a gas. The manifold has an inlet coupled to receive a liquid flow from the tank and inlets configured to receive gas flows. The gas flows may be from an upper portion of the liquid tank. An expansion chamber in the manifold receives the liquid flow and the gas flows, which create a liquid-gas vortex or circulation around the expansion chamber that produces foam.

The invention discloses a method and a system for quickly leading foam of a foam pump of a compressed air foam system, the method is as follows: an electromagnetic control emptying valve which is opened and closed under the control of a PLC (Programmable Logic Controller) is mounted at an outlet of the foam pump of the compressed air foam system, when the compressed air foam system is started, the PLC opens the electromagnetic control emptying valve to enter emptying time; and after the emptying time is up, the PLC closes the electromagnetic control emptying valve, and the foam pump pumps the foam to a mixing pipeline of the compressed air foam system, so that the mixing of the water, the foam and the air is completed.
