Fluidics W2-50-45 nozzle

The Fluidics W2-50-45 nozzle is an oil nozzle, catalogue article 480.892.078. Parts of this type are precision consumables that atomise the fuel oil into a fine cone so that it burns completely within the combustion head. The nozzle is a replaceable component that sits between the oil pump and the burner combustion head; it works together with the pump solenoid valve and, where fitted, the preheater. Such nozzles are selected by three parameters that together define how the flame sits in the blast tube: flow rate in GPH or kg/h at a reference pressure, spray angle (typically between 30° and 80°), and spray pattern (hollow, solid, or semi-solid). The thread size must match the burner adapter. The data for this specific article—rating, angle, pattern, and thread—are not stated here and must be taken from the burner data plate or the supplier’s specification for catalogue number 480.892.078. When replacing an oil nozzle, all three parameters (flow, angle, pattern) must match the burner design. Using the correct rating but the wrong pattern can cause sooting, pulsation, or unstable ignition, while an incorrect angle may impinge the flame on the combustion head or heat exchanger. Always confirm the existing nozzle markings or the burner manual before ordering.
