It delivers a steady flow rate of 1.75 gallons per hour at a rated pressure of 100 PSI. The 45 degree spray angle gives it a wide, even cone pattern that works well across a broad range of residential oil-fired furnaces, boilers, and water heaters. HVAC technicians and heating contractors rely on this type of nozzle to atomize fuel oil into a fine mist, which allows for efficient combustion inside the heat exchanger. Proper atomization reduces soot buildup, lowers stack temperature, and improves overall system efficiency. The Type W spray pattern is known as an all purpose pattern, meaning it suits a wide variety of burner heads and combustion chamber shapes. This makes it a go-to choice when technicians need a versatile replacement nozzle that works in multiple system configurations. The nozzle body is constructed from brass for corrosion resistance and long service life. The orifice disc is made from steel, which holds its shape under repeated thermal cycling and maintains accurate flow rate over time. A sintered filter is built into the nozzle to catch debris before it reaches the orifice, helping to prevent clogging and erratic spray patterns. The nozzle is manufactured to ISO 9001 quality standards, so technicians can count on consistent performance from part to part. This is a direct replacement nozzle for residential oil burners that require a 1.75 GPH, 45 degree, W pattern configuration. It is a standard thread size that fits most common burner assemblies used in North American residential heating systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1.75 GPH flow rate at 100 PSI rated pressure for consistent fuel delivery\u003c\/li\u003e\n\u003cli\u003e45 degree W all purpose spray pattern fits a wide range of residential oil burner configurations\u003c\/li\u003e\n\u003cli\u003eBrass body with steel orifice disc and sintered filter for durability and debris protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 1.75-45-w provides reliable, consistent atomization for residential oil burners with a versatile all purpose spray pattern and ISO 9001 certified construction.
