Delavan 75-80a1 Oil Burner Nozzle 0.75 Gph 80 Degree Type a

Product Description

The DELAVAN 75-80a1 is a Type A hollow cone oil burner nozzle rated at 0.75 gallons per hour (GPH) with an 80-degree spray angle. It atomizes fuel oil into a fine, hollow cone pattern for efficient combustion in residential and light commercial oil-fired heating equipment. The hollow cone spray pattern distributes fuel along the outer edge of the cone, which suits certain burner head geometries and combustion chamber designs. Oil burner service technicians install this nozzle as a maintenance replacement during annual tune-ups or when combustion performance degrades.

This nozzle is suited for use in residential oil-fired furnaces, boilers, and water heaters where the burner manufacturer specifies a Type A hollow cone nozzle at 0.75 GPH and an 80-degree angle. The 80-degree wide-angle pattern is commonly used in shorter, wider combustion chambers. Always match nozzle type, flow rate, and spray angle to the equipment manufacturer's specification for the specific burner model being serviced.

Key Features

• 0.75 GPH flow rate for precise fuel delivery in low-to-mid input oil burners
• 80-degree spray angle suits wide or shallow combustion chamber geometries
• Type A hollow cone pattern concentrates atomized fuel at the outer cone perimeter
• Standard oil burner nozzle thread for direct replacement fitment
• Designed for use with No. 1 and No. 2 fuel oil

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired furnaces, boilers, and water heaters that specify a Type A hollow cone nozzle at 0.75 GPH and 80 degrees. Confirm burner manufacturer specifications before installation.

Installation Notes

Oil burner nozzles are installed by qualified oil burner service technicians. Shut down the burner and allow the system to cool before servicing the nozzle assembly. Use a proper nozzle wrench to remove and install the nozzle to avoid damaging the nozzle adapter or electrodes. Replace the nozzle filter and inspect the strainer, electrodes, and igniter during each nozzle change to ensure reliable burner operation.
