NITROGEN GAS GENERATORS
Gas Generation Solutions designs and supplies on-site nitrogen gas generators for industrial customers across the United States, Mexico, and Canada. We supply both PSA and membrane systems and build complete packages with feed-air compressors, high-pressure boosters, and buffer tanks. Incorporated in 1979, we have over 40 years of industry experience and have deployed thousands of systems. Our average customer recovers the full investment in 12 to 14 months and runs the system for 20 years or more.
On-site generation produces nitrogen from ambient air at up to 90% lower cost than delivered gas. There are no long-term gas contracts, no delivery fees, and no price escalators. Systems are sized to your exact flow, purity, and pressure requirements, with nitrogen purity available from 95% up to 99.9995%. All systems are USA-built.
This page lists the primary industries and applications we serve. For a full technical overview of how a nitrogen generator works, see /nitrogen-generator/.

How Our Nitrogen Gas Generators Work
We supply two generation technologies. PSA (Pressure Swing Adsorption) nitrogen generators use twin carbon molecular sieve beds that cycle between adsorption and regeneration, pulling oxygen out of compressed air to produce nitrogen at purities from 95% up to 99.9995%. PSA is the right choice when the application needs tight residual oxygen control, such as heat treating, metal 3D printing, reflow soldering, or food packaging with low O2 targets. For more detail, see /what-is-a-psa-nitrogen-generation-system/.
Membrane nitrogen generators use hollow-fiber polymer membranes to separate oxygen and nitrogen by permeation. Membrane systems are compact, have no moving parts in the separation stage, and deliver nitrogen at purities typically from 95% up to 99.5%. They are a strong fit for tire inflation, fire suppression, pipeline purge, laser cutting at lower purity, and general inert blanketing. For more detail, see /what-is-a-membrane-nitrogen-generation-system/.
Every package we build includes right-sized air compression, air treatment (dryers and filters), nitrogen storage, and controls. We quote the complete system so there are no hidden add-ons after purchase.
Industries We Serve
Below is an alphabetical list of the primary industries and applications our nitrogen gas generators support. Click any heading to go to the detailed industry page.
Nitrogen generators for the aerospace industry support heat treating of alloys, inert environment testing, propellant gas supply, pneumatic tool driving, and specialty manufacturing processes. On-site generation gives aerospace plants consistent purity and uninterrupted supply without cylinder handling or tanker deliveries.
Nitrogen generators for aluminum degassing remove hydrogen from molten aluminum by sparging nitrogen through the melt. Dissolved hydrogen attaches to the rising nitrogen bubbles and is carried out of the liquid. Nitrogen sparging is the dominant degassing method in aluminum casting operations.
Nitrogen generators for aluminum extrusions blanket the die face to prevent oxide buildup during the extrusion run. Controlling oxide on the die surface extends die life, reduces surface defects on the extruded profile, and improves first-pass yield.
Nitrogen generators for autoclaves create an inert atmosphere at the operating pressure and temperature of the cycle. Pressurizing with dry nitrogen displaces oxygen, water vapor, and other contaminants from the compressed air supply, improving process repeatability and reducing combustion risk.
Nitrogen generators for cannabis packaging stop the oxidation that degrades THC and CBD and protect terpene and flavor profiles during storage. Flush-packaging cannabis flower, pre-rolls, and edibles with nitrogen is standard practice for licensed manufacturers, research facilities, and dispensaries.
Nitrogen generators for cheese packaging support modified atmosphere packaging (MAP), usually with a nitrogen and CO2 blend. Flushing residual oxygen to below 1% preserves color, controls mold growth, and extends shelf life for shredded, sliced, and block cheese.
Nitrogen generators for chips and snack packaging displace oxygen in the pack before the seal is made. The nitrogen flush preserves flavor, color, and texture and extends shelf life, which is especially important for high-oil snacks like chips and nuts.
Nitrogen generators for coffee packaging protect roasted whole bean, ground coffee, and pod formats from oxidation of coffee oils and loss of volatile aromatics. On-site nitrogen also supports cold brew and nitro infusion applications.
Nitrogen generators for electronics manufacturing supply the inert atmosphere needed for clean soldering. Operating a reflow, wave, or selective soldering oven without nitrogen exposes solder joints to oxidation and raises the risk of dross, bridges, and weakened connections.
Food grade nitrogen generators produce nitrogen at 99% purity or higher, meaning residual oxygen of 1% or less. This is the baseline food-grade specification, and many packaging lines target purity higher than 99.9% for longer shelf life.
Nitrogen generators for food packaging support MAP, gas flushing, and headspace displacement across a wide range of product categories. Switching from delivered gas to on-site nitrogen generation is one of the largest operating-cost reductions most packaging lines see.
Nitrogen generators for heat treating and belt furnace annealing supply the inert atmosphere needed for clean processing of steel, copper, aluminum, and specialty alloys. Purity, flow, and pressure are sized to the furnace geometry and the metallurgy of the parts being treated.
Industrial nitrogen generators are built for demanding duty cycles and hostile environments. Stainless-steel construction, explosion-proof designs, and containerized skids are available for corrosive, hazardous, or remote installations including mining operations.
Nitrogen generators for laboratories and medical applications supply carrier gas and sample-prep nitrogen for GC, GC/MS, LC/MS, and evaporation. On-site generation removes the tank-swap interruptions that disrupt instrument runs and clinical workflows.
Nitrogen generators for laser cutting supply high-pressure assist gas for cutting stainless steel, mild steel, aluminum, and aluminum alloys. On-site nitrogen replaces bottled and bulk supply, removing the largest recurring cost in a high-volume laser cutting operation.
Nitrogen generators for metal 3D printing and additive manufacturing hold the build chamber inert. Nitrogen displaces oxygen, preventing unwanted oxidation reactions and thermal deformation in the powder bed and reducing scrap on long builds.
Nitrogen generators for pet food packaging preserve freshness, color, and texture in kibble, treats, and wet-pack formats. The nitrogen flush removes residual oxygen and moisture from the bag or tray before sealing.
Nitrogen generators for pharmaceutical manufacturing and packaging supply the clean, dry inert atmosphere required for tablet bottling, vial headspace, blister pack flushing, and API handling. Purity is sized to the product and the validation requirements of the line.
Nitrogen generators for plastic injection molding supply the nitrogen used as a propellant in gas-assist molding and film extrusion. Injection systems typically operate in the 150 to 175 PSI range, which on-site generation delivers with a booster package.
Nitrogen generators for popcorn packaging displace oxygen before the seal to preserve flavor, color, and the delicate texture of the corn. This is particularly important for flavored and oil-coated popcorn, where oxidation drives off-notes fastest.
Nitrogen generators for reflow soldering reduce oxidation and dross build-up in the reflow oven. Consumer electronics manufacturers use on-site nitrogen to improve joint quality, lower rework rates, and reduce the cost of nitrogen consumed across multiple oven zones.
Nitrogen generators for salad condiment packaging support nitrogen flush on vertical bagging and form-fill-seal machines. The inert atmosphere protects dressings, toppings, and dry condiment mixes from oxidation during shelf life
Nitrogen generators for salad packaging flush lettuce and salad-mix bags to preserve freshness and extend shelf life. The bag is inflated with nitrogen immediately before the greens are deposited and the pack is sealed.
Nitrogen generators for selective soldering inert the chamber around the soldering nozzle. This reduces dross, produces cleaner and more corrosion-resistant joints, and lowers the rework rate on mixed-technology boards.
Nitrogen generators for semiconductor manufacturing purge process chambers, vacuum systems, waste abatement lines, and process piping. Fab operations consume very large nitrogen volumes, and on-site generation sized with bulk backup is the dominant supply model.
Nitrogen generators for snack food packaging remove oxygen from the package before the seal is made. Nitrogen preserves flavor, color, and texture and extends shelf life across chips, puffs, pretzels, crackers, and mixed snack formats.
Nitrogen generators for vacuum heat treating furnaces supply the backfill and partial-pressure gas used in most cycles. Nitrogen is the standard backfill because it is non-reactive with most metallurgies, shortens heat-up time under positive pressure, and is the lowest-cost inert gas to run on-site.
Nitrogen generators for wave soldering inert the environment around the solder wave, reducing corrosion and dross. Wave soldering typically tolerates lower nitrogen purity than reflow and selective, which can lower the size and cost of the generator required.
Nitrogen generators for wine bottling supply the sparging and blanketing nitrogen that protects wine from dissolved oxygen during transfer, filtration, and bottling. On-site generation gives wineries continuous supply during crush and bottling season without tank swaps.

Frequently Asked Questions
How does a nitrogen gas generator work?
A nitrogen gas generator separates nitrogen from the other gases in compressed air. PSA generators use carbon molecular sieves to adsorb oxygen, and membrane generators use hollow-fiber polymers to permeate oxygen out of the air stream. The nitrogen that remains is stored in a buffer tank and delivered on demand at the purity, flow, and pressure your application needs.
What nitrogen purity can an on-site nitrogen gas generator deliver?
Our nitrogen gas generators deliver purity from 95% up to 99.9995%. Membrane systems typically cover 95% up to 99.5%. PSA systems cover the full range and are the right choice for applications that need residual oxygen below 1,000 ppm, such as heat treating, metal additive manufacturing, reflow soldering, and high-spec food packaging.
How much can a nitrogen gas generator save versus delivered gas?
Most customers cut their nitrogen operating cost by up to 90% when they switch from delivered bulk or cylinder gas to on-site generation. Savings begin immediately when the generator starts and delivered gas stops. The exact percentage depends on current gas spend, local delivery costs, and purity requirements.
What is the payback period on a nitrogen gas generator?
Typical payback is 12 to 14 months. Higher-volume and higher-purity applications can pay back sooner because the gap between delivered-gas cost and generated-gas cost is wider. We provide an ROI calculation against your current gas spend as part of every quote.
How long do nitrogen gas generators last?
Our nitrogen gas generators are built to run for 20 years or more. Carbon molecular sieve and membrane modules are long-life components when the feed air is properly dried and filtered, which is why every system we supply includes matched air treatment.
Should I choose a PSA or a membrane nitrogen gas generator?
Choose PSA when the application requires nitrogen purity higher than 99.5% or residual oxygen below 5,000 ppm. Choose membrane for compact installations at purities of 95% to 99.5%, for tire inflation, fire suppression, laser cutting at lower purity, and general blanketing. We will recommend the right technology after reviewing your flow, purity, and duty cycle.
Does Gas Generation Solutions size the full system?
Yes. Every quote includes the generator, an appropriately sized air compressor, air treatment (dryer and filters), nitrogen storage, and controls. Sizing the full package prevents the undersized-compressor and under-dried-air problems that shorten sieve and membrane life.
What industries use on-site nitrogen gas generators?
Aerospace, pharmaceutical and biotech, food and beverage, electronics manufacturing, laser cutting, metal 3D printing, heat treating, semiconductor fabs, wineries, cannabis, research laboratories, mining, and industrial manufacturing.
