Standard Whirl Jet nozzles(FIRE FIGHTING NOZZLES) feature a hollow cone spray pattern with a ring-shaped impact area and spray angle of 340 to 900. They produce a uniform distribution of small to medium sized droplets over a wide range of flow rates and pressures. These Nozzles produce excellent results in applications requiring good atomization of liquids at lower pressures, especially where quick heat transfer or effective air-borne droplet impingement is required.
