Fluidics 40.00GPH, 60SF nozzle

An oil nozzle is the component that atomises the fuel oil into a fine spray before it enters the combustion head. This ensures complete combustion and stable flame formation. The nozzle is a precision consumable; its internal geometry determines the flow rate, spray angle, and spray pattern (hollow, solid, or semi-solid). These three parameters must be selected together, because they define how the flame sits relative to the air pattern and the combustion chamber. Using a nozzle with the correct flow rate but wrong spray angle or pattern can cause sooting, pulsation, or ignition instability. This particular article is a Fluidics oil nozzle listed under catalogue number 480.892.049. As with any nozzle of this class, the replacement must match the burner manufacturer’s specification. When ordering, verify the required flow rate (typically in GPH or kg/h at the reference pressure), the spray angle (commonly between 30° and 80°), and the pattern designation from the burner data plate or service manual. Also check the thread size to ensure it fits the nozzle holder. The product name on this article includes codes that conventionally indicate flow rating and spray characteristics, but always confirm these against the actual burner data rather than relying on the name alone. A mismatched nozzle will impair combustion performance and may cause lockout or excessive soot formation.
