Monarch Nozzle 3.50 X 45AR

The Monarch 3.50 x 45AR Oil Burner Nozzle is a high-output, precision-engineered atomising nozzle designed for reliable combustion in medium-to-large oil-fired heating systems. Delivering 3.50 US gallons per hour at 100 psi, it provides a 45° spray angle with an AR-type (hollow cone) spray pattern. This configuration ensures efficient fuel dispersion, stable ignition, and optimal flame shape for heavy-duty burners operating under higher fuel flow conditions.
