A nitrogen generator makes on-site nitrogen (N₂) from compressed air. In the process, oxygen, water vapor and other gases are removed via technologies such as Pressure Swing Adsorption (PSA) or membrane separation. You thus create a continuous, pure nitrogen flow at the pressure and purity level your process requires – without relying on cylinders or external suppliers.
JustAir offers industry partners a unique combination of reliability, cleanliness, durability and cost efficiency:
Precision in purity: from standard purity levels (approx. 95-98 %) to ultra-pure nitrogen (99.9-99.999 %) for processes in food, pharmaceuticals, electronics.
Always available, independent of suppliers: no waiting time, no delivery problems, no storage of large gas cylinders or tanks.
Long-term cost effectiveness: lower operating costs than gas deliveries, no tank rental costs, no transportation costs. JustAir recovers your investment through Return on Investment (ROI) calculations based on your consumption.
Energy & environmental optimization: efficient technology, integrated compressors and purification, minimal waste; less CO₂ impact than external gas supplies.
Multi-language service & monitoring: JustAir provides installation, preventive maintenance, 24/7 monitoring of purity & performance; reporting and KPI dashboards included.
Flexible solutions & scalability: from small units for specific machines/labs to large systems for entire production lines; also possible through Air-as-a-Service (AaaS) models.
| Technology | Advantages | Application / suitable when… |
|---|---|---|
| PSA (Pressure Swing Adsorption). | Very high purity, long-term stable, suitable for large flow rates. | Your application requires purging, inerting, blanketing, heat treatment or where oxidation must be strictly avoided. |
| Membrane separation | More compact, lower initial investment, easier maintenance, fast startup. | For lower to medium purity (e.g. 95-99 %), smaller flow rates, mobile or limited space. |
Both processes require prior air purification (drying, filtering) and good compressors. JustAir provides complete packages that include these components.
Our nitrogen generators are successfully used in, among others:
Food & Packaging Industry (Food & Beverage)
For Modified Atmosphere Packaging (MAP), storage, blanketing to prevent oxidation of flavors.
Pharmacy & Healthcare
Inert atmosphere in manufacturing, packaging, lab work, where sterilization & purity are critical.
Chemicals & petrochemicals
For blanketing, purge, protection of reaction vessels (safety against oxidation or explosions).
Electronics & welding processes
Soldering, wave & reflow soldering, laser cutting, where oxygen free environment is required to monitor quality & surface finish.
Metalurgy & Heat Treatment
Inert gas atmosphere during heating/cooling, blanketing of boilers or heat chambers.
Vehicle & tire industry
Fill tires with nitrogen for more stable pressure, less oxygen & moisture-induced degradation.
Laboratories & test facilities
For analytical techniques, instrumental use, where precisely regulated gas conditions are required.
When considering a nitrogen generator, these are the key parameters that JustAir identifies and optimizes:
Purity level: what % N₂ is required (95 %, 98 %, 99.9 %, 99.999 %)
Flow rate/flow: m³/h or Nm³/h – how much nitrogen your process needs per minute/hour
Working pressure: connecting to your system, minimizing pressure loss
Occurring evaporation, moisture, oil: preliminary steps in filtration and drying necessary for generator life and quality of output
Regeneration or energy consumption (for PSA especially) – JustAir looks at optimal temperature level, purge air consumption, heat recovery where possible
Reliability & maintenance: what maintenance interval, what spare materials, redundancy in critical components
Safety: monitoring purity, oxygen sensors, proper ventilation, proper certification
| Tradition | JustAir on-site nitrogen generator |
|---|---|
| Delivery via cylinders/tanks → logistics, storage space, delivery interruptions | Continuous stable delivery, no logistical dependencies |
| Rental/tank rental/transportation costs | Long-term savings, lower operating costs |
| Uncertainty in purity / pressure / availability | Exact matching to your process needs, with monitoring and reliability |
| Potential safety risks in gas cylinder/tank storage | Reduced risk of leaks, dangerous situations; JustAir provides safety & certification |

ROI-oriented proposals: concrete calculations of payback, cost savings, reduction of downtime & quality issues
Food packaging company switched from cylinders to JustAir PSA unit with 99.9% purity. Result: savings on gas deliveries by ± 40-60 %, no delivery problems, longer product shelf life.
Pharmaceutical manufacturer had problems with oxidation in packaging process; with JustAir generator and purity control, failure and quality claims dropped by significant percent.
Metal processing company used nitrogen during heat treatment process; thanks to generator now stable inert atmosphere, better consistency, less rust after treatment & transport.
