Abstract

There is provided a fire-fighting apparatus comprising a positive pressure blower generating an airstream at an outlet, and a high-flow spray head having a plurality of low-dispersion droplet generators mounted at substantially equally spaced positions proximate to said outlet for generating and projecting water droplets within said air stream Thereby a long-range concentrated stream of droplets can be produced. There is further provided a high-flow multi-nozzle spray head and a long-range low-dispersion spray nozzle comprising a body defining an inlet bore and outlet orifice, an impingement assembly comprising an elongated conical deflector and a downstream diffuser having a plurality of forwardly oriented tabs, and at least one arm connecting a downstream end of the impingement assembly to the body.
