Why On Site’s N2 Generator for Laser Cutting?

Nitrogen gas is the top choice for the laser cutting industry due to its non-reactive properties, especially when cutting stainless steel and aluminum. It offers a clean cut without any additional heat being conducted, and it gets the job done fast. But as any laser cutter knows, an efficient process is crucial to succeed. With an N2 generator from On Site Gas Systems at your laser cutting job site, you will be able to improve your productivity while reducing your costs. Here’s why:

We Deliver Pure Nitrogen Gas for Optimum Results

As you may know, the purity of the nitrogen gas you use is vital to the quality of your end result. If you want the crispest edge when laser cutting aluminum or stainless steel, even the smallest amount of oxygen contamination will affect the appearance of the cut. It can cause a yellowing of the metal or form dross that needs to be removed. The purity of the nitrogen gas is especially important when you are laser cutting thick pieces of stainless steel. Since the speeds have to be lower, there is more time for the materials to react with the oxygen.

With an N2 generator from On Site Gas Systems, you never have to worry about quality. Our nitrogen gas is produced at a 99% to 99.999% purity without sacrificing the pressure output possibilities.

We Custom Build N2 Generator Systems Specifically for You

We understand that not every laser cutting facility is the same, which is why we ask several questions to determine the ideal N2 generator for your specific needs. Some of the questions we ask are:

  • What type of laser do you use? What model is it, who is the manufacturer, and what is the wattage?
  • What types of metals do you cut in your facility? How thick does the metal get, and what is your preferred pressure output?
  • When cutting the thickest metals, what size is the nozzle you use?

With the answers in tow, we put together a nitrogen gas system that can deliver the results you expect, both in purity and in flow rate.

We Cut Your Nitrogen Gas Costs Dramatically

With an N2 generator at your site, you don’t have to worry about the logistics or expenses associated with using bulk nitrogen gas. Instead, you can save up to 80% by producing your own nitrogen gas on site. Even when accounting for the upfront and maintenance costs of the N2 generator, you can save hundreds of thousands of dollars. When comparing the figures, most laser cutting companies say that switching to on site nitrogen gas is a no brainer.


For almost 30 years, On Site Gas Systems has been improving the operations at laser cutting facilities across the world. Our American-made N2 generator produces the nitrogen gas right at your job site, improving productivity while increasing your bottom line.
