💨 Delavan 30609-005 (SNA .50) Siphon Nozzle – Air Atomizing
The Delavan 30609-005 (SNA .50) siphon nozzle produces a solid cone spray pattern with extremely fine fuel droplets at low air pressures and low CFM. Its large passages reduce clogging and allow reliable flow of low-volume fuels. Ideal for waste oil applications, this nozzle ensures efficient combustion and consistent performance.
This nozzle is also compatible with CleanBurn 32000 and may require an adapter (Part #17147) for installation in some systems.
✅ Key Features
-
✅ Fine Atomization at Low Air Pressure – Produces optimal spray with lower CFM requirements.
-
✅ Solid Cone Spray Pattern – Ensures uniform fuel distribution for efficient combustion.
-
✅ Clog-Free Operation – Large passages reduce the risk of fuel blockage.
-
✅ Versatile Installation – Can operate horizontally or vertically; lift measured from fuel level to nozzle face.
-
✅ Waste Oil Compatible – Works with #2, #4, and other low-viscosity oils.
-
✅ Replacement Compatibility – Same as CleanBurn 32000; adapter may be required (Part #17147).

🛒 Shopping & Installation Tips
-
Check Replacement Compatibility – Confirm your system uses Delavan SNA .50 or CleanBurn 32000.
-
Air Supply Requirements – Ensure your air compressor can provide at least 10% more air than specified for proper lift.
-
Fuel Connections – Tight fuel and air connections are critical for correct lift and spray characteristics.
-
Orientation – Nozzle works in horizontal or vertical positions; measure lift from liquid level to nozzle face when vertical.
-
Adapter Requirements – Some installations may require adapter Part #17147.
-
Maintenance – Regularly inspect for wear or clogging to maintain optimal performance.
❓ FAQ (Frequently Asked Questions)
Q: What fuels can the 30609-005 handle?
A: Works best with #2 and #4 waste oils, low-viscosity fuels, and similar oils.
Q: Can it replace CleanBurn 32000?
A: Yes, the 30609-005 is functionally equivalent to CleanBurn 32000.
