Patent ID: 8701789

Claim:
A method for producing compressed air foam (CAF) for fire fighting and for decontamination comprising the steps of: providing a main water stream; producing a foaming agent stream by a pneumatically or electrically operated admixing pump that is connected to a foaming agent reservoir, wherein producing the foaming agent stream comprises: first aspirating a separate auxiliary and motive water stream from the main water stream, such that the separate auxiliary and motive water stream is injected into the admixing pump; then, suctioning an additive off a separate reservoir by the auxiliary and motive water stream, wherein the additive is adjusted to an application case and specific to the type of fire or decontamination; and suctioning the foaming agent into the additive-water mixture, wherein, the additive is suctioned into the auxiliary and motive water stream first, followed by the foaming agent; mixing, after the step of producing a foaming agent stream, the auxiliary and motive water stream, including the additive and foaming agent, with the main water stream; and loading the combined foaming agent and main stream, after the step of mixing, with a compressed air stream at a foaming line.
