💨 Delavan 30609-008 (SNA .75) Siphon Nozzle – Waste Oil Nozzle
The Delavan 30609-008 (SNA .75) 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 32001 and Lanair 9766, and may require an adapter (Part #17147) for some installations.
✅ 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 32001 and Lanair 9766; adapter may be required (Part #17147).

🛒 Shopping & Installation Tips
-
Check Replacement Compatibility – Confirm your system uses CleanBurn 32001, Lanair 9766, or Delavan SNA .75.
-
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 30609-008 handle?
A: Works best with #2 and #4 waste oils, low-viscosity fuels, and similar oils.
Q: Can it replace CleanBurn 32001?
A: Yes, the 30609-008 is functionally equivalent to CleanBurn 32001 and Lanair 9766.
