HH series full cone nozzle features a hexagon construction,a roundish nozzle tip and a X-shape lamina.

Usually the narrower the spray angle, the higher the impact you'll receive at a given distance and the further the trajectory.  Therefore narrower angle nozzles are used for cleaning or chemical injection and wider angle nozzles are used for dust suppression, coating, general washing, rinsing and similar applications.  The droplet sizes generated by full cone nozzles are considered to be fine to coarse.
