The DELAVAN 00700-80a7 is a Type A hollow-cone oil burner nozzle rated at 7.00 gallons per hour (GPH) with an 80-degree spray angle. It is designed for residential oil-fired heating equipment where a hollow cone air pattern is required. The brass body and steel orifice disc construction provide durability under continuous burner cycling. A sintered filter element is integrated into the nozzle assembly to protect the orifice disc from debris in the fuel supply. This nozzle operates at a rated pressure of 100 psi and is suited for fuel flow applications up to 2.00 GPH where lower throughput hollow-cone nozzles are appropriate alongside higher-output units in the same product family.
The 00700-80a7 is intended for residential oil burner installations where the burner head produces a hollow cone air pattern. The hollow-cone spray concentrates droplet distribution on the outer edge of the cone, which promotes reliable ignition and low-noise combustion. This nozzle is well suited to forced-air oil furnaces, oil-fired boilers, and similar residential heating appliances that require precise fuel atomization at the specified flow rate and angle. A licensed oil burner technician or HVAC service professional typically selects and installs this nozzle as part of an annual burner tune-up or combustion efficiency service.
Designed as an OEM-style replacement nozzle for residential oil burners that specify a Type A hollow-cone nozzle at 7.00 GPH and an 80-degree spray angle.
Oil burner nozzle replacement is performed by a licensed oil burner technician or qualified HVAC service professional. Shut down the burner and allow the system to cool before removing the old nozzle. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes. After installation, verify combustion performance with a flue-gas analyzer per standard residential oil burner commissioning practice.
