A global catalog manufacturer and a specialist supplier
Parker Hannifin is one of the world's largest diversified manufacturers of motion and control technologies. Nitrogen generation is one product line within its Industrial Gas Filtration and Generation Division, offered under brands including NITROSource, Balston, and domnick hunter, and sold worldwide through a distribution network. Parker offers both membrane and PSA nitrogen generators, and its NITROSource PSA line delivers 95% up to 99.9995% nitrogen purity.
Gas Generation Solutions was incorporated in 1979 and has over 40 years in business. We are a specialist supplier of USA-built PSA and membrane nitrogen generators sized for anything from a single production line to facility-wide demand: laser cutting, electronics manufacturing, soldering, food packaging, heat treating, and similar applications. We also take on large custom-engineered generation projects built to formal specification packages, and we support multi-location corporate contracts across the United States, Mexico, and Canada. Every system is sized against your measured nitrogen usage, and every generator ships with a built-in oxygen analyzer so you can verify purity from day one.
A nitrogen generator comparison is only useful when it is honest. Parker is an established global manufacturer, and for many buyers its standardized catalog is a strong choice. This page explains what each company specializes in, what to compare before you buy, and where an on-site nitrogen generator from Gas Generation Solutions is the better fit.

How to compare nitrogen generator quotes
Whether you are comparing Parker, Gas Generation Solutions, or any other nitrogen generator supplier, the same six factors decide whether a system performs and pays back. Use this checklist on every quote.
01
Purity your process actually needs
Purity drives system size and operating cost. Food packaging typically runs 99% to 99.9%, laser cutting 99.9% up to 99.9995% depending on the laser, and selective soldering 99.99% to 99.999%. Specifying higher purity than the process needs inflates every number in the quote.
02
PSA or membrane technology
PSA systems are efficient across the full purity range up to 99.9995%. Membrane systems are simple and compact but practical up to about 99.5%. The right answer is a purity question, not a brand question.
03
Air-to-nitrogen ratio
Every SCF of nitrogen costs compressed air, and the ratio climbs with purity. Ask each manufacturer for the air consumption at your purity and flow. It is the single biggest driver of electrical operating cost, and quotes are not comparable without it.
04
Measured demand, not a guess
An oversized generator wastes capital and an undersized one starves your process. Gas Generation Solutions sends you a free nitrogen flow meter so you can measure real usage before anyone sizes a system. Data beats nameplate estimates every time.
05
Total cost of ownership
Compare purchase price plus compressed air, filters, and sieve or membrane life over 20 years, then set that against what delivered nitrogen costs today. On-site generation typically cuts nitrogen cost by up to 90% with payback in 12 to 14 months.
06
Support after startup
Ask who answers the phone in year five. Gas Generation Solutions supports every system with sizing, system drawings, startup procedures, operator training, and parts, and serves the United States, Mexico, and Canada.

Which nitrogen generator supplier fits your project
The honest way to choose a nitrogen generator supplier is to match how each company sells and supports to how you want to buy. Here is where the line falls.
Where Parker's lineup is aimed
- Catalog buying through distribution. If a standard NITROSource model matches your purity and flow, and you are comfortable specifying and buying through a distributor, Parker's broad catalog covers it.
- One line in a very large portfolio. Nitrogen generation is a single product family inside a diversified motion and control manufacturer, so sizing and after-sale support typically run through the distribution channel rather than a dedicated nitrogen specialist.
Gas Generation Solutions is the better call when
- You need nitrogen in a manufacturing facility. Laser cutting, electronics soldering, food packaging, heat treating, and blanketing are the applications we size every week, from one machine to the entire facility.
- The project needs custom engineering. We deliver large custom-engineered generation projects to formal specification packages, including engineering drawings, data sheets, and customer-specified purity, pressure, and ambient requirements, with per-unit capacity to 100,000 SCFH and units chained for higher flow.
- You operate more than one plant. Multi-location corporate contracts standardize nitrogen generation across sites in the United States, Mexico, and Canada, with support for corporate fleets at sites abroad.
- You want the system sized on data. We send you a free nitrogen flow meter so the system is sized against your measured demand, not a guess that gets padded upward.
- Purity has to be provable. Every generator ships with a built-in oxygen analyzer, so purity is verified at the buffer tank from day one. That matters for food, pharma, and electronics audits.
- Payback drives the decision. Most customers cut nitrogen cost by up to 90% versus delivered gas and reach full payback in 12 to 14 months, on a system designed to run for 20 years or more.
- You want a direct line, not a ticket queue. We support systems across the United States, Mexico, and Canada, and you talk to the people who sized your system.
Before you compare suppliers, measure your demand
The most expensive mistake in on-site nitrogen is buying a system sized to a guess. Whichever manufacturer you choose, start with real numbers. Here is how we do it at Gas Generation Solutions.
- Talk through your deliveries and usage. A short call about what you pay for delivered nitrogen today, and how your demand runs across shifts, tells us most of what sizing needs.
- Measure with a free flow meter. We ship a cellular nitrogen flow meter to your site at no charge. It streams usage data to a web dashboard, so both of us can see your real peak and average demand before a system is proposed.
- Size the system and show the payback. We size to your measured flow, purity, and pressure, then set the system cost against your current nitrogen spend. Most customers save up to 90% versus delivered gas and reach payback in 12 to 14 months, and the cost breakdown is itemized so you can compare it line by line against any other quote.
Frequently Asked Questions
Is Parker a good nitrogen generator manufacturer?
Yes. Parker Hannifin is a large, established global manufacturer, and its NITROSource PSA line delivers 95% up to 99.9995% purity across a broad standardized catalog. The question for most buyers is not quality but fit: a global catalog sold through distribution is a different buying experience from working directly with a specialist who sizes and supports your system. Which one is right depends on how you want to buy and be supported.
What is the difference between Parker and Gas Generation Solutions?
Both companies offer PSA and membrane nitrogen generators from 95% up to 99.9995% purity. Parker sells a broad standardized catalog worldwide through a distribution network, as one product line within a large diversified manufacturer. Gas Generation Solutions is a specialist supplier that sizes each system against measured demand using a free flow meter, ships every generator with a built-in oxygen analyzer standard, builds in the USA, and supports systems directly across the United States, Mexico, and Canada.
Do both companies offer PSA and membrane nitrogen generators?
Yes. The choice between PSA and membrane should follow your purity requirement, not the brand. PSA is efficient across the full range up to 99.9995% purity. Membrane is simple and compact and works well up to about 99.5%, but its air consumption rises sharply beyond that. Gas Generation Solutions quotes both technologies and recommends whichever fits your purity and flow.
What nitrogen purity can an on-site generator deliver?
PSA nitrogen generators from Gas Generation Solutions deliver 95% up to 99.9995% purity, which covers food packaging, laser cutting, soldering, laboratory, and pharmaceutical applications. Membrane systems are a practical choice from 95% to about 99.5%. Every Gas Generation Solutions generator includes a built-in oxygen analyzer that reads purity at the buffer tank, so output is verified rather than assumed.
How should I size a nitrogen generator before requesting quotes?
Measure your actual nitrogen usage first. Gas Generation Solutions sends you a free cellular nitrogen flow meter that streams live usage data to a web dashboard, capturing your true peak and average demand. Sizing from measured data instead of a nameplate guess prevents both oversizing, which wastes capital, and undersizing, which starves your process. It also makes competing quotes directly comparable.
How much does switching to on-site nitrogen generation save?
Most customers cut their nitrogen cost by up to 90% compared to delivered cylinders, dewars, or bulk liquid, and reach full payback in 12 to 14 months. The generators are designed to run for 20 years or more, so the savings continue long after payback. Savings begin immediately when the system starts and delivered gas stops.
