Ransburg NO-2: The Revolution in Electrostatic Coating Technology
What makes the Ransburg NO-2 so unique? While conventional electrostatic spray guns still rely on compressed air or airless technology, the NO-2 uses 100% pure electrostatic atomization. The result: Virtually no material loss and perfect coating results even on the most complex geometries.

The Secret: Pure Electrostatic Atomization
Unlike conventional systems, the Ransburg NO-2 atomizes the paint exclusively through electrostatic forces and transports it to the workpiece:
How it works:
- The rotating bell charges the paint particles negatively
- Electric field lines guide the particles to the grounded workpiece
- No compressed air or centrifugal forces required
- The paint is literally "pulled" onto the workpiece
This principle eliminates overspray completely—a decisive advantage over all other electrostatic systems.
Why the NO-2 Is Unbeatable for Delicate Parts
When coating grids, fences, railings, or wire products, the Ransburg NO-2 shows its full potential. While traditional spraying methods waste 80–95% of the material, the NO-2 works with almost 100% transfer efficiency.
| Application Scenario | Challenge | NO-2 Solution |
|---|---|---|
| Grids & Fences | High overspray between bars | Paint follows field lines around edges |
| Railings & Forged Items | Hard-to-reach areas | Electrostatic wraparound effect |
| Wire Goods | Thin profiles, high paint consumption | Precise application with no losses |
🎯 Precise Wraparound
Electrostatic effect coats rear sides and hard-to-reach areas
⚡ No Energy Waste
No high pressure, no compressed air—only electrostatic forces
🌬️ Absolute Cleanliness
No overspray means a clean workshop and healthier working conditions
Use the electrostatic wraparound effect for complex parts—the NO-2 coats even areas that are not directly in the spray path.
The Key Technical Differences
| Feature | Conventional Electrostatics | Ransburg NO-2 |
|---|---|---|
| Atomization Principle | Compressed air or airless | Pure electrostatic |
| Overspray | Yes, with material loss | Practically none |
| Wraparound Effect | Limited | Strong |
| Energy Consumption | High (pressure + electrostatics) | Only electrostatics |
Where the NO-2 Excels
✅ Ideal for:
- Fence and grid elements
- Forged parts and railings
- Wire mesh and baskets
- Window grilles and gates
- Playground equipment and park benches
❌ Less ideal for:
- Very large flat surfaces
- Non-conductive materials
- High-viscosity specialty coatings
Note: Conductive primers can be used for non-conductive materials such as wood or plastic.
Economics: The Numbers Speak for Themselves
When coating delicate parts, the NO-2 pays off immediately:
Cost Comparison for 100 Liters of Paint:
- Without Electrostatics: 5–20 liters on the workpiece = 80–95 liters waste
- Standard Electrostatics: approx. 50 liters on the workpiece = 50 liters waste
- Ransburg NO-2: 95–98 liters on the workpiece = 2–5 liters waste
At a price of €20 per liter, this means: Instead of €2,000 paint cost for 100 liters with 80% waste (€1,600 loss), with the NO-2 you only pay for the amount you actually need.
