Make your own nitrogen.
On-site generators produce nitrogen from your existing compressed air, replacing cylinder and bulk liquid supply.
Pressure swing adsorption or membrane
Two routes to on-site nitrogen. The right one depends on the purity your process needs.
| PSA (pressure swing adsorption) | Membrane | |
|---|---|---|
| How it works | Carbon molecular sieve beds in a two-bed alternating cycle for continuous output | Hollow fibre membranes separate the gases |
| Purity | 95% to 99.999% | 95% to 99% |
| Character | Highest purity range | Simpler and more compact, with fewer moving parts |
| Suited to | Electronics, pharmaceuticals, laser cutting, chemical processing | Tyre inflation, fire suppression, some food packaging, general inert atmospheres |
No deliveries, no rental, no reordering.
- Supply on demand, with generators running up to 24/7
- Removes delivery, rental and reordering costs
- Safer: no high-pressure cylinders, cryogenic vessels or manual handling
- Continuous real-time purity monitoring
- Modular, scalable systems
- Reduced transport emissions and liquefaction energy use
Where nitrogen is put to work
Food packaging
Modified atmosphere packaging.
Beverage
Blanketing and purging.
Laser cutting
Assist gas; 99.5%+ purity typically needed.
Electronics
Wave soldering and reflow ovens.
Chemical processing
Blanketing, purging, pressure testing.
Pharma and life sciences
Inert atmospheres, validation support.
Tyre inflation
Claimed to reduce fuel use and tyre wear.

Nitrogen FAQ
How much can on-site nitrogen save?
J&J state up to 80% lower cost than cylinder or bulk liquid nitrogen, with payback typically in 1 to 3 years depending on usage. Share your monthly consumption for a payback model.
Does the generator need compressed air?
Yes. Generators produce nitrogen from your existing compressed air, so compressor and air treatment specification is part of the job.
