Built in the USA: A Behind-the-Scenes Look at Our Manufacturing Process
Why U.S. Manufacturing Matters
When reliability is critical to your operations, you want to know exactly where and how your equipment is built. At On Site Gas Systems, we’re proud to manufacture our nitrogen and oxygen generators right here in the USA. From design to final testing, everything we do is centered on quality, speed, and long-term reliability.
Being transparent about how our generators are made helps build the kind of trust our industrial partners expect. This behind-the-scenes look gives you a closer view into our production process and what makes our American-made systems different.
Where It All Begins: Our U.S.-Based Facility
All of our systems are manufactured at our fully integrated facility in the United States. Engineering, fabrication, assembly, and testing all happen under one roof, which means tighter quality control and faster turnaround times.
Our centralized approach eliminates unnecessary delays and gives our team complete control over each build. This is how we ensure that every oxygen and nitrogen generator leaving our facility meets the highest standards. Our facilities and quality management systems are ISO certified.
Precision Engineering: Designing Custom Gas Generation Systems
Every project starts with a conversation.
Our engineering team works directly with your business to understand your application—flow rate, pressure, purity, and usage demands.
From there, we move into system design. Our team builds solutions tailored to your exact needs, utilizing proven PSA and membrane technology. This collaborative design process ensures each unit performs as expected, with no overbuilt or underperforming components.
This is the foundation of how nitrogen generators are made USA-style—custom, smart, and built to last.
Fabrication and Assembly: Craftsmanship You Can Count On
After engineering approval, we move to fabrication and assembly. We use high-quality materials sourced and fabricated right here in the U.S. Our skilled technicians and engineers build and test every system—whether it’s a PSA oxygen generator, a PSA nitrogen system, or a membrane nitrogen unit.
Precision and durability are key. Everything is built in alignment with U.S. safety and performance standards, ensuring a reliable operation for years to come. If you’re wondering how oxygen generators are made USA-based, this is where our reputation for dependability begins—at the hands of experienced professionals on American soil.
Shipping and Support: From Our Facility to Your Facility
Once your generator is ready, it’s shipped directly from our U.S. facility. No overseas delays. No customs hold-ups. That means you get your equipment faster, get it installed sooner, and start producing gas without waiting around.
In fact, U.S. manufacturers deliver products up to 50% faster on average compared to overseas suppliers, thanks to shorter lead times and streamlined logistics.
And we’re not just shipping and forgetting. As one of the most trusted N2 and O2 manufacturers in the USA, we offer long-term service and support from our U.S.-based team—people who know your system and are available when you need them.
Built to Last, Built in the USA
For over 35 years, our U.S.-based manufacturing operation has grown alongside the industries we serve. From healthcare and defense to food processing and aerospace, we’ve expanded our capabilities to meet evolving demands—without sacrificing quality or lead time.
As one of the most established N2 manufacturers in the USA, we’ve helped critical industries reduce dependence on imported systems while gaining more control over supply, service, and system performance. Because we build every system domestically, we’re able to maintain consistent standards, adapt to changing customer needs, and provide faster, more reliable delivery and support. Our customers are investing in equipment that’s backed by decades of U.S. engineering experience and a support team that stands behind every order.
When you choose a nitrogen or oxygen generator made in the USA, you’re setting your operation up for long-term success with a partner that grows with you.
Proudly Built by On Site Gas Systems
Every system we build reflects our commitment to quality, speed, and dependability. From engineering to installation, everything happens right here in the U.S. It’s how we deliver consistent performance and long-term value—without the risks of overseas production.
