It delivers a flow rate of 3.50 gallons per hour at a spray angle of 45 degrees. HVAC technicians and oil burner service professionals rely on this nozzle for consistent, efficient fuel atomization in forced-air oil furnaces and boilers. The solid cone spray pattern distributes fuel droplets uniformly throughout the complete spray pattern. This uniform distribution supports smooth ignition and efficient combustion, especially in larger residential burners. At flow rates above 8.00 GPH the spray pattern becomes progressively more hollow, but at 3.50 GPH this nozzle performs at its designed optimum. The brass body construction provides durability and resistance to corrosion from fuel oil contact. The steel orifice disc controls the precise flow and atomization of the fuel. A Monel strainer filter protects the orifice from debris and particulates that could affect spray quality. The nozzle is rated for operation at 100 PSI pressure and a temperature rating of 80 degrees F, consistent with standard residential oil burner system specifications. Manufactured to ISO 9001 quality standards, the Delavan 3.50-45-b meets the performance requirements expected by professional HVAC technicians performing oil burner maintenance, tune-ups, and replacements. Proper nozzle selection is critical for combustion efficiency, fuel economy, and system cleanliness. Using the correct GPH rating and spray angle ensures the right amount of fuel is atomized and delivered to the combustion chamber. This nozzle is a direct replacement part for residential oil heating equipment requiring a 3.50 GPH, 45-degree, Type B solid cone nozzle. Keep spares on hand for annual oil burner service calls.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType B solid cone spray pattern for uniform droplet distribution and efficient combustion\u003c\/li\u003e\n\u003cli\u003e3.50 GPH flow rate at 100 PSI with a 45-degree spray angle for residential oil burners\u003c\/li\u003e\n\u003cli\u003eBrass body with steel orifice disc and Monel strainer filter for durability and clean fuel delivery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 3.50-45-b solid cone oil burner nozzle provides reliable atomization and smooth ignition for residential heating systems.
