An improved method and apparatus for delivering compressed particulate solid fire fighting agent includes a pneumatic system for entraining particulate fire fighting agent in a high pressure gas stream, compressing the agent into quasi-discrete quasi-solid slugs, and delivering the compressed slugs in a constant stream at a high rate of speed to the center of the fire being fought from a safe distance. The system includes a high pressure gas supply, a pressure regulator, a pressure compensator, a pressure sink, an agent storage vessel, and a multi-stage delivery nozzle including a pressure imbalance mechanism. Particulate agent is sequentially compressed in the multiple nozzle stages by virtue of a pulsating gas supply effect, and ejected in a constant stream of solid slugs at speeds near or above Mach 1.
