Australia’s leaders in manufacturing on-site Nitrogen Generators for the industrial and commercial industries.

On Site Gas Systems have a range of products suited for use across hundreds of applications and for businesses of all sizes. The nitrogen generators we have for sale are custom built for each application to meet the user’s exact purity, pressure and flow requirements. Follow your industry category above to learn more about how the systems can help you and your application.


On-site nitrogen generation by way of non-cryogenic air separation can be achieved using PSA generation and membrane generation.
The systems we have for sale offer both air separation technologies so you can be sure you will get the best recommendation for your application even in remote locations.

Nitrogen Membrane Generation Technology

With almost no moving parts, membrane-based models are an ultra-reliable means to produce the gas on site. These systems are particularly well suited to applications that require less than 98% purity, portability, or both. So if you are looking for a portable generator, get in touch with us to chat about our membrane nitrogen generators.

PSA Nitrogen Generation Technology (pressure swing adsorption)

PSA systems are well suited for applications where it is expected to be in a fixed location or purity requirements are high. PSA technology can reliably generate nitrogen up to 99.9995% and are more efficient at higher purities than membranes are.


  • Oil, gas and coal
  • Chemical
  • Medical
  • Tank inerting
  • Electronics manufacturing
  • Laser cutting
  • Laboratory

And many more manufacturers can benefit from on-site nitrogen generators.

Benefits of on-site nitrogen gas generators

Having a system on-site offers a reliable, on-demand stream to your process while offering significant cost savings and a fast return on investment. It is the most cost-effective means of nitrogen generator gas supply available – it can be generated for as low as 3c per m3 – that can be up to a 90% cost saving compared to out-sourced supplies.
