What is the function of the foam concentrate in an eductor?

The function of the foam concentrate in an eductor is primarily to generate a cooling effect. When foam concentrate is introduced into the water stream via the eductor, it helps create a foam solution that is effective in suppressing flammable liquids and cooling down burning materials. This foam acts as a barrier between the fuel and the fire, reducing the heat and preventing reignition.

When utilizing foam, the cooling effect prevents the surroundings from reaching the ignition temperature and assists in extinguishing the flames more efficiently by reducing the overall heat. While other components like pressure can be factors in a broader sense, they do not define the foam concentrate's specific role within the eductor system directly tied to fire suppression tactics. The primary purpose of the foam concentrate, in this context, is to enhance the firefighting capabilities by providing cooling and smothering properties.
