Ransburg NO-2 vs. Conventional Systems: The Complete Comparison
Are you deciding on a new coating system? In this comprehensive comparison, we analyze the Ransburg NO-2 against conventional electrostatic, airless, and air-atomizing systems. Learn which system is best suited for your specific requirements.
The Decisive Factor: Transfer Efficiency Compared
Transfer efficiency determines how much of the sprayed coating actually lands on the workpiece. With delicate parts, the differences are dramatic:
| Coating System | Transfer Efficiency* | Material Loss |
|---|---|---|
| Without Electrostatics | 5–20% | 80–95% |
| Standard Electrostatics | Approx. 50% | 50% |
| Airless Electrostatics | 40–60% | 40–60% |
| Ransburg NO-2 (pure electrostatic) | 95–98% | 2–5% |
*Reference values for delicate parts such as grids, fences, and railings
💨 Air Atomizing
High overspray, good quality, high energy consumption, suitable for all materials
🔫 Airless
Fast, high pressure, medium quality, ideal for large surfaces, high material consumption
⚡ Ransburg NO-2
Minimal overspray, best efficiency, ideal for conductive materials and delicate parts
With a paint price of €25 per liter, the NO-2 saves approx. €1,125 in material costs per 100 liters compared to standard electrostatics. The investment often pays for itself within a few months.
Technology Comparison: How the Systems Differ
| Technology Aspect | Conventional Electrostatics | Ransburg NO-2 |
|---|---|---|
| Atomization Principle | Compressed air or airless + electrostatics | 100% pure electrostatic |
| Energy for Transport | Compressed air/high pressure + electrostatics | Only electrostatic forces |
| Overspray Formation | Yes, due to centrifugal effects | Virtually none |
| Wrap-Around Effect | Limited | Strong (field lines) |
| Maintenance Effort | Medium (nozzles, air system) | Low (no nozzles) |

Request NO-2 Quote NowConclusion: Clear Recommendations Depending on Application
For delicate metal parts: The Ransburg NO-2 is unbeatable. The 95–98% paint yield and strong wrap-around effect make it the top choice for fences, grids, railings, and all complex metal structures.
For large, flat surfaces: Conventional airless or electrostatic systems can play to their strengths here, especially when high area performance is required.
For mixed applications: Many companies choose a combination: NO-2 for delicate parts and a conventional system for large surfaces. This way, you make optimal use of each system’s strengths.
