Delavan 0.85-80-ar-d Oil Burner Nozzle 0.85 Gph 80 Degree Ar-d Solid Cone

Product Description

The Delavan 0.85-80-ar-d is a Type AR-D solid cone oil burner nozzle designed for residential heating applications. It delivers a flow rate of 0.85 GPH at a rated pressure of 100 PSI with an 80 degree spray angle. The AR-D designation means this nozzle produces a solid cone spray pattern similar to the Type B nozzle, but with a slightly lower droplet concentration at the center of the cone. This distribution makes it well suited for burners operating at low to medium capacity, handling flows up to 2.00 GPH. HVAC technicians and oil burner service professionals rely on nozzles like this one to achieve proper atomization, efficient combustion, and clean startup in oil-fired heating systems. The brass body provides corrosion resistance and durability under repeated heating and cooling cycles. The steel orifice disc maintains a precise and consistent spray pattern over the service life of the nozzle. A sintered filter is integrated into the nozzle to trap contaminants before they reach the orifice, helping prevent clogging and extending nozzle life. This nozzle meets ISO 9001 quality standards, giving technicians confidence in dimensional accuracy and consistent performance from unit to unit. Proper nozzle selection is critical in oil burner service. The flow rate, spray angle, and spray pattern must all match the burner manufacturer specifications for the appliance to operate at peak efficiency. Incorrect nozzle selection can lead to incomplete combustion, sooting, poor fuel economy, and nuisance lockouts. The Delavan 0.85-80-ar-d is a direct-replacement nozzle for residential oil burners requiring an 0.85 GPH, 80 degree, AR-D specification. It is a standard industry fitting and compatible with most residential oil burner heads. Keep replacement nozzles on hand for annual tune-up calls and service visits.

• Type AR-D solid cone spray pattern with slightly lower center droplet concentration than Type B for balanced combustion
• Brass body and steel orifice disc construction for durability and corrosion resistance in residential oil heating systems
• Integrated sintered filter protects the orifice from fuel contaminants, reducing clogging and service callbacks

Product Highlights

The Delavan 0.85-80-ar-d delivers precise 0.85 GPH flow at 80 degrees with an AR-D solid cone pattern, making it a reliable replacement nozzle for residential oil burner service and annual tune-ups.
