Abstract

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.
