Delavan 1.75-45-w 1.75 Gph 45 Degree W All Purpose Oil Burner Nozzle

Product Description

The Delavan 1.75-45-w is a Type W All Purpose oil burner nozzle designed for residential heating applications. 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.
