A compressed-air foam (CAF) nozzle has a stationary barrel and a distributor assembly with typically three outlets which are angled and skewed against each other. The distributor assembly is rotatably connected to the barrel and rotates when a stream of fluid is passed through the nozzle. The nozzle enables the delivery of a CAF stream at a relatively wide delivery angle without significantly collapsing the bubble structure of the foam.

La lance active la fourniture d'un courant de MAC selon un angle de fourniture relativement large sans affaisser significativement la structure en bulles de la mousse.
