If you’re considering switching to on-site nitrogen generation, one of your first questions is probably: “How much does a nitrogen generator cost?” The answer very much depends on your application, flow rate, and required purity — but the long-term savings are almost always worth the initial investment.
Typical Price Range
The cost of a nitrogen generator can range from £3,000 to over £50,000, depending on the following factors:
- Flow rate requirements (measured in l/min, Nm³/h or SCFM)
- Nitrogen purity level (e.g. 95%, 99.9%, or 99.999%)
- Compressed Air Source can be part of the system if house air is not in place
- Additional equipment such as an Oxygen Analyser
- Installation & commissioning (optional but recommended)
Common System Cost Examples
| Generator Type | Purity | Typical Flow Rate | Approx. Cost (GBP) |
| Compact PSA Unit | 95%–99.9% | Up to 10l/min | £3,000–£8,000 |
| Mid-Range PSA Generator | 99.5%–99.999% | Up to 20Nm3/hr | £10,000–£25,000 |
| High-Capacity System | 99.999% | 20+ Nm³/hr | £30,000–£50,000+ |
