It is designed for residential oil-fired heating systems and serves as a flexible replacement option across a wide range of burner configurations. The Type W spray pattern falls between a true hollow cone and a true solid cone, producing a semi-hollow distribution that adapts to varying air patterns without the sensitivity of a dedicated cone type. Construction uses a brass body with a steel orifice disc, and the nozzle includes a sintered filter element. It is rated to 100 psi and 80 degrees F, making it suitable for standard residential oil burner operating conditions.\u003c\/p\u003e\u003cp\u003eThis nozzle is applied in residential oil-fired heating equipment where a versatile spray pattern is needed. Type W nozzles are interchangeable across a flow range of 0.40 to 8.00 GPH and are compatible regardless of the burner air pattern, giving service technicians flexibility when matching replacements on the job. At lower flow rates, the spray pattern trends toward a more hollow cone distribution. It is a common go-to nozzle for oil burner service calls where the exact original nozzle specification is unknown or when a single nozzle type covers multiple units in a service route.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType W all-purpose spray pattern works across hollow and solid cone applications\u003c\/li\u003e\n\u003cli\u003e1.00 GPH flow rate at standard residential operating pressure\u003c\/li\u003e\n\u003cli\u003e90-degree spray angle for wide coverage in standard residential burner heads\u003c\/li\u003e\n\u003cli\u003eBrass body with steel orifice disc for durability in fuel oil service\u003c\/li\u003e\n\u003cli\u003eSintered filter element integrated into the nozzle assembly\u003c\/li\u003e\n\u003cli\u003eRated to 100 psi pressure and 80 degrees F operating temperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an all-purpose replacement oil burner nozzle for residential oil-fired heating systems with burner assemblies accepting standard 1.00 GPH nozzles.

Shut down the burner and allow the system to cool before removing the old nozzle. Use an appropriately sized nozzle wrench to avoid damaging the nozzle adapter or electrodes during removal and installation. After replacement, verify ignition, flame quality, and combustion efficiency with appropriate test equipment before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Oil Burner Nozzle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: W - All Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 1.00 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 100 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 80 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Disc Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Sintered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: ISO 9001\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DELAVAN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00100-90w1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51468193956146,"sku":"00100-90W1","price":17.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945176.jpg?v=1783914043","url":"https:\/\/voomisupply.com\/products\/delavan-00100-90w1-oil-burner-nozzle-1-00-gph-90-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
