💨 Hago SN609-11 (SN9011, 60070) 1.00 GPH Siphon Nozzle – Air Atomizing
The Hago SN609-11 siphon nozzle is engineered for precise air atomization of waste oil and other variable fuel oils. Designed to deliver a solid cone spray pattern at low air pressures, it ensures fine fuel droplets for efficient and clean combustion. Ideal for applications where fuel viscosity is too high for standard pressure atomizing nozzles.
This nozzle is a direct replacement for Delavan SNA1.00, SNA 1.00, 30609-11, and 3060911, providing a simple, reliable solution for maintaining optimal burner performance.
✅ 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.
 
- 
✅ Multiple Fuel Grade Capability – Works with #2, #4, and pre-heated #5 and #6 fuel oils.
 
- 
✅ Durable Construction – 416 stainless steel parts with brass stem and Viton “O” ring.
 
- 
✅ Air Atomizing Technology – Combines air and fuel in a precision mixing chamber for uniform swirl and fine droplets.
 
- 
✅ Replacement Nozzle – Compatible with Delavan SNA1.00, SNA 1.00, 30609-11, 3060911.

🛒 Shopping & Installation Tips
- 
Verify Fuel Compatibility – Ensure the nozzle is suitable for the fuel you plan to use (#2, #4, or pre-heated #5/#6 oil).
 
- 
Check Replacement Model – Confirm it replaces your existing Delavan nozzle (SNA1.00, 30609-11) or equivalent.
 
- 
Air Pressure Requirements – Make sure your system can provide the required air pressure (3–5 PSIG) for proper atomization.
 
- 
Flow Rate Confirmation – Verify your burner system requires a 1.00 GPH flow rate.
 
- 
Proper Installation – Handle nozzle parts carefully, avoid scratches, and ensure the Viton O-ring is properly seated for a secure fit.
 
- 
Maintenance – Periodically check for clogging or wear to maintain efficient combustion and fine atomization.
 
- 
Stock a Spare – Keep a spare nozzle on hand to minimize downtime in critical applications.
 
❓ FAQ (Frequently Asked Questions)
Q: What fuels can the SN609-11 handle?
 A: #2, #4, and pre-heated #5 and #6 fuel oils. Best for viscous fuels that are difficult for direct pressure nozzles.
Q: Can this nozzle replace Delavan SNA1.00?
 A: Yes — it is a direct replacement for SNA1.00, 30609-11, and other equivalent models.
Q: How does air atomization work?
 A: Air and fuel are separately routed to the nozzle and mixed in a precision chamber. Air pressure then swirls the fuel through the orifice to produce a solid cone spray of fine droplets.
Q: Will variations in air or fuel affect performance?
 A: Yes — flow rates, spray angles, and droplet sizes can vary with changes in air velocity, lift, or fuel conditions.
