Spiral nozzle inject water into a spiral extrude orifice. Different from ordinary nozzle, spray pattern of spiral nozzle is not a complete cone, it's a uneven spray pattern instead. This nozzle is a hollow cone nozzle. Spray angle is various from 50° to 170°, flow range from 5.5 to 4140 LPM at 3 bar. Spiral nozzle has compact structure and fluent runner design, which helps reduce hydraulic resistance at the greatest extent and maximize flow capacity.
