Fluidics W2-350-50 nozzle

This is a Fluidics W2-350-50 oil nozzle, catalogue article 480.892.106, listed under the brand Fluidics in the oil nozzles category. Oil nozzles of this type are precision consumable components that atomise fuel oil into a fine spray cone so it can mix with air and burn completely. The nozzle sits between the oil pump and the combustion head; pressurised oil from the pump enters the nozzle and is forced through an internal swirl chamber and orifice to produce a defined spray pattern, angle, and flow rate. Selection of such a nozzle depends on three parameters that must all match the burner manufacturer’s data plate: the flow rate given in GPH or kg/h at the reference pressure, the spray angle (typically 30 to 80 degrees), and the spray pattern (hollow, solid, or semi-solid). Using a nozzle with the correct flow rate but wrong pattern can cause sooting, pulsation, or unstable ignition, so all three must be confirmed before replacement. The thread size is also a key mechanical fit detail. When replacing an oil nozzle of this type, always verify the existing nozzle’s stamped numbers and compare them with the burner specification. Because the nozzle is a direct consumable part with no serviceable internals, correct selection is the only way to maintain safe and efficient combustion. No other compatibility or performance data beyond the name, article number, and brand is available from the source information for this specific article.
