Delavan 30609-7 Siphon Air Atomizing Nozzle

Product Description

The DELAVAN 30609-7 is a siphon air atomizing (SNA) nozzle designed for use in waste oil burner and furnace applications. It atomizes fuel by drawing air through a siphon mechanism, producing a fine spray pattern suitable for burning non-standard fuel stocks such as used motor oil and other waste oil blends. The nozzle designation 9-7 is stamped directly on the side of the unit along with the Delavan part number. HVAC technicians and waste oil heating specialists install this nozzle when fuel weight variations require an adjustment away from the standard nozzle configuration.

This nozzle is not issued as a standard component with any Clean Burn burner or furnace model. It is intended as an alternative selection when the fuel being burned differs in viscosity or weight from standard used motor oil. Delavan siphon air atomizing nozzles are widely used across multiple waste oil furnace manufacturers and burner platforms, making the 30609-7 a versatile service part for technicians working in commercial and light industrial heating environments where waste oil is the primary fuel source.

Key Features

• Siphon air atomizing (SNA) design for effective atomization of variable-weight waste oil fuels
• Nozzle designation 9-7 stamped on the side for field identification
• Compatible with Clean Burn systems as an alternative nozzle for non-standard fuel weights
• Suited for use across multiple waste oil furnace and burner manufacturers
• Allows fuel-weight adjustment without modifying the burner assembly

Compatibility

This nozzle is not standard with any specific Clean Burn burner or furnace model. It is used as an alternative replacement across a range of waste oil furnace and burner platforms when fuel weight or viscosity differs from the standard used motor oil specification. Confirm nozzle sizing and spray pattern requirements against the burner manufacturer guidelines before installation.

Installation Notes

Installation should be performed by a qualified HVAC technician or waste oil heating specialist. Shut down the burner and allow all components to cool before removing or replacing any nozzle. Use the correct nozzle wrench to avoid damage to the nozzle body or burner head threads. Verify that the replacement nozzle flow rate and spray pattern are appropriate for the fuel type and burner firing rate before returning the unit to service.
