Fluidics 5.00GPH, 60SF nozzle

This Fluidics oil nozzle is rated at 5.00 GPH and carries the designation 60SF. It is a precision consumable part that atomises fuel oil into a fine spray cone for complete combustion in an oil burner. The flow rate (GPH) is specified at the burner’s reference pressure, and the spray angle and pattern together determine how the flame sits in the combustion head. Nozzles of this type are selected by three parameters: flow rate in GPH or kg/h, spray angle (typically 30° to 80°), and spray pattern (hollow, solid, or semi-solid). The 60 in the designation refers to the spray angle in degrees; the SF part of the code indicates the pattern type, though the exact meaning should be confirmed with the burner manufacturer’s specification. A nozzle with the correct flow but wrong pattern can cause sooting, pulsation, or unstable ignition, so all three parameters must match the burner data plate. When replacing an oil nozzle, always verify the existing nozzle’s markings and consult the burner manual. Use only the specified GPH, angle, and pattern. The nozzle thread and length must also be compatible with the burner head, though these details are not given here.
