Delavan 01000-70A7 Hollow Cone Spray Nozzle 10.00 Gph

Product Description

The DELAVAN 01000-70A7 is a hollow cone spray nozzle with an integrated mesh strainer, designed for oil-fired burner applications. Rated at 10.00 gallons per hour (GPH) with a 70-degree spray angle, this nozzle atomizes fuel oil into a hollow cone pattern for efficient combustion. The built-in mesh strainer helps protect the nozzle orifice from particulate contamination, supporting consistent spray performance over the service interval. This nozzle is a standard replacement component installed by HVAC technicians and oil burner service professionals during routine maintenance or combustion tune-ups.

This nozzle is suited for residential and light commercial oil-fired heating equipment, including forced-air furnaces and boilers using No. 2 fuel oil. It is typically installed during annual burner servicing when combustion efficiency, CO levels, or smoke readings fall outside acceptable ranges. The A spray pattern designation indicates a hollow cone configuration, which is appropriate for burner heads designed to work with this atomization style.

Key Features

• 10.00 GPH flow rate for precise fuel delivery at rated firing pressure
• 70-degree spray angle for broad hollow cone atomization
• Hollow cone spray pattern compatible with burner heads specifying this configuration
• Integrated mesh strainer reduces orifice clogging from fuel contaminants
• Standard nozzle body sizing for straightforward installation in compatible nozzle adapters

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired burners requiring a 10.00 GPH, 70-degree, hollow cone (A-pattern) spray nozzle.

Installation Notes

Installation should be performed by a qualified oil burner technician. Shut off power to the burner and close the fuel supply valve before removing the existing nozzle. Use an appropriate nozzle wrench to avoid damaging the nozzle adapter or electrodes during removal and installation. After installation, verify combustion performance with appropriate test instruments before returning the system to service.
