Fluidics 45.00GPH, boquilla 60SF

The Fluidics 45.00GPH, 60SF nozzle (catalogue article 480.892.043) is an oil nozzle designed for use in oil burners. Parts of this type atomise fuel oil into a fine spray cone so that it mixes with combustion air and burns completely. The nozzle is a precision consumable component: its rating, spray angle and pattern together determine how the flame sits inside the combustion head. For any oil burner, the correct nozzle must be selected by flow rate (given here in USGPH at the reference pressure), spray angle (commonly 30–80 degrees), pattern (hollow, solid, or semi-solid) and thread size. Using a nozzle with the correct flow rate but the wrong pattern can cause sooting, pulsation or unstable ignition, so all three parameters must match the burner data plate. This specific nozzle is listed with a flow rate of 45.00 GPH and a designation of 60SF. While the exact spray angle and pattern implied by "60SF" are not detailed here, such markings typically indicate the spray angle and pattern type (e.g., 60 degrees, solid pattern). A heating engineer sourcing a replacement should verify that these parameters correspond to the burner manufacturer’s specification. The nozzle is a direct consumable that sits in the oil pump line, downstream of the solenoid valve and preheater if present. When replacing, ensure the thread type matches the burner head and that the nozzle is installed without overtightening, as deformation can alter the spray characteristics.
