What it is

The Danfoss 3.00 x 45 S nozzle is an oil burner nozzle used in oil-fired boiler applications. It is manufactured by Danfoss and carries the part number 030F4140. The nozzle meters and atomises the oil supply at the burner head, and its size and spray angle determine the flow rate and spray pattern delivered into the combustion chamber.

Signs this part needs replacing

  • Soot deposits building up on the boiler baffles or heat exchanger
  • Unstable or pulsating flame, or repeated burner lockouts
  • Rising CO readings or a smoky exhaust at the flue
  • Visible wear, blockage or damage at the nozzle orifice
  • Poor combustion efficiency despite correct pump pressure and air settings

Before you order

  • Confirm the nozzle size and spray angle stamped on the existing nozzle match 3.00 and 45.
  • Check the type designation S against the burner manufacturer's specification.
  • Verify the burner model and appliance details before fitting.
  • Confirm the part number 030F4140 against the manufacturer's parts list.
