The RA hollow cone nozzle is an axial nozzle that delivers a finely atomized spray aligned with the inlet supply pipe. Inside the nozzle, a precisely machined swirl vane with two spiral grooves enables a wide range of flow capacities, starting from very low levels. The strong centrifugal force in the vortex chamber creates a high-speed liquid rotation, resulting in an atomized mist. For small-capacity RA hollow cone nozzles, it is recommended to install an appropriate filter before the inlet orifice to prevent clogging.
