Abstract:
A rotary nozzle for compressed air foam (CAF) has a barrel (14) mount ed for rotation about an axis perpendicular to its longitudinal axis. The barrel is mounted to a CAF supply conduit (10) and has a cross-sectional area substantially larger than the cross-sectional area of the conduit. Two non-equal orifices in the barrel (24, 26), located on the opposite sides of the axis of rotation, distribute CAF such that it covers an almost complete, typically a circular area on the ground.
