What is a Nitrogen Generator Used For? Key Applications and Benefits
From keeping packaged food fresh to protecting high-rise buildings, nitrogen generators are becoming essential across industries. Instead of relying on truck-delivered cylinders, more companies are investing in on-site nitrogen production for its cost savings, reliability, and safety.
The question is: what is a nitrogen generator used for, and why are so many industries making the switch? Let’s break down the basics, explore applications, and highlight the benefits of industrial nitrogen generators.

What is a nitrogen generator?
A nitrogen generator is a system that produces nitrogen gas directly from compressed air. Using either pressure swing adsorption (PSA) or membrane technology, it separates nitrogen molecules from oxygen and other gases, delivering a steady stream of high-purity nitrogen.
How nitrogen generators work (PSA and membrane technology)
-
PSA nitrogen generators use carbon molecular sieves to trap oxygen molecules while letting nitrogen pass through.
-
Membrane nitrogen generators filter air through polymer membranes that separate oxygen and nitrogen.
Both methods provide a safe, on-demand nitrogen supply without the hassle of storing or refilling gas cylinders.
Why businesses are moving away from nitrogen cylinders
-
Cost savings: No recurring delivery fees.
-
Safety: No heavy cylinders to transport or store.
-
Convenience: Nitrogen is always available when you need it.
-
Sustainability: Reduced environmental footprint from eliminating deliveries.
Key applications of nitrogen generators
Nitrogen has unique properties, it’s inert, dry, and non-flammable, making it invaluable in multiple industries. Here’s what a nitrogen generator is used for across different fields:
-
Fire protection systems
Nitrogen is used to fill dry and pre-action sprinkler systems, preventing corrosion inside pipes. By displacing oxygen, it extends the lifespan of fire protection infrastructure and reduces costly maintenance.
-
Food and beverage packaging
In food packaging, nitrogen replaces oxygen inside bags or containers to slow spoilage and keep products fresh. From chips and coffee to bottled beverages, nitrogen maintains quality and extends shelf life.
-
Pharmaceuticals
Pharmaceutical companies use nitrogen to prevent oxidation during production and storage. It helps maintain the purity of sensitive medicines and vaccines.
-
Electronics manufacturing
In electronics, even small traces of oxygen can damage components. Nitrogen creates controlled, oxygen-free environments that reduce defects and ensure product reliability.
-
General industrial use
Nitrogen is also widely used in:
-
Inerting tanks and pipelines
-
Purging oxygen before welding
-
Blanketing volatile chemicals
Benefits of nitrogen generators
Adopting an on-site nitrogen generator delivers advantages that go beyond convenience.
1. Reduced long-term costs
While bulk deliveries add up over time, a nitrogen generator is a one-time investment that lowers ongoing expenses.
2. Continuous on-demand nitrogen supply
Generators ensure you’ll never “run out” of nitrogen during critical operations.
3. Improved safety and reduced handling risks
No more moving heavy gas cylinders or worrying about high-pressure storage hazards.
4. Lower environmental impact
Eliminating cylinder deliveries means fewer trucks on the road and a greener footprint.

Choosing the right nitrogen generator
Not every business needs the same solution.
Factors to consider: flow rate, purity, application
-
Flow rate: How much nitrogen do you need per hour?
-
Purity level: Food and pharma often require 99.9% purity, while fire protection systems may need less.
-
Application: Match the system to your specific industry requirements.
