Fluidics 12 W2-160-45 nozzle

This is a Fluidics 12 W2-160-45 oil nozzle, catalogue article 480.892.056. Oil nozzles of this type are precision consumable parts that atomise fuel oil into a fine cone so it can burn completely. The spray pattern, flow rate and spray angle together define how the flame sits in the combustion head. For a replacement to function correctly, all three parameters must match the burner data plate: flow rate in GPH or kg/h at the reference pressure, spray angle (typically 30–80 degrees), and spray pattern (hollow, solid or semi-solid). A nozzle with the correct rating but the wrong pattern can cause sooting, pulsation or unstable ignition. In the oil system, the nozzle is mounted in the combustion head and receives pressurised fuel from the oil pump. It works in combination with the solenoid valve and, where fitted, the preheater. When replacing a nozzle, verify the thread size and ensure the nozzle is clean and free of damage before fitting. Always check the burner manufacturer’s specifications for the exact flow rate, angle and pattern required for the application.
