Fluidics W1-115-50 nozzle

The Fluidics W1-115-50 oil nozzle, catalogue article 480.892.085, is a precision consumable component used in oil-fired burners. Its function is to atomise the fuel oil into a fine cone, enabling complete combustion. The nozzle is a wearing part and must be replaced periodically to maintain burner efficiency and stable flame. Correct selection of a replacement nozzle depends on three parameters: flow rate (rated in GPH or kg/h at a reference pressure), spray angle (typically between 30 and 80 degrees), and spray pattern (hollow, solid, or semi-solid). The thread size must also match the burner adapter. Installing a nozzle with the correct flow rate but wrong pattern can cause sooting, pulsation, or unreliable ignition, so all three specifications must be taken from the burner data plate. This specific article is listed under the Fluidics brand and the reference number 480.892.085. When sourcing a replacement, verify that the nozzle rating, angle, and pattern on the packaging correspond to the burner manufacturer’s requirements. There is no universal cross‑reference; the data plate is the only valid source. If the original nozzle is worn or damaged, replace it with a unit of identical specification to avoid combustion problems.
