1. The spiral nozzle structure is a compact, anti-clogging and environmental protection nozzle with a wide range of uses. 2. The liquid passes through the tangent of the spiral body smaller and smaller, then collides with tiny droplets and sprays, resulting in two spray shapes: hollow cone or solid cone. 3. The jet angle range can be 60-180 under 3bar pressure, liquid flow range is 5.5-4140L/min. 4. This type of nozzle provides a male thread connection, usually the 1/4 inch to 1 inch nozzle is made of stainless steel 5. Sprayed by small water droplets generated after the liquid and the small continuous spiral body are tangents and collided. 6. The unique shape of the nozzle minimizes clogging and allows the largest liquid flow channel to allow the liquid to get the maximum flow rate over a pipe of a given size.
