A nitrogen generator is a modern, efficient solution for businesses in Australia that require a reliable, high-purity nitrogen supply for various applications. These systems work by separating nitrogen molecules from the air, eliminating the need for high-pressure cylinders or bulk liquid nitrogen. At On Site Gas Systems, we offer a range of nitrogen gas generators that are engineered to meet diverse industrial needs, focusing on cost savings, safety, and environmental sustainability.
Our nitrogen generators can be customised to suit your specific requirements, whether you need a membrane nitrogen generator or a pressure swing adsorption (PSA) system. We use advanced nitrogen membrane technology to deliver reliable and cost-efficient solutions. We provide nitrogen generators with purities ranging from 95% to an impressive 99.9995%, ensuring that you get the high-quality nitrogen you need for your business operations.
By switching to an on-site nitrogen gas generator, you can eliminate the risk of running out of gas, reduce your exposure to price increases, and free yourself from being locked into contracts by traditional gas supply companies. This solution offers significant long-term benefits, including greater control over your gas supply and the ability to scale with your business’s evolving needs.
Contact us today to explore the possibilities and find the perfect nitrogen gas solution for your business!
Nitrogen generators generally use one of two separation technologies: Pressure Swing Adsorption (PSA) or Membrane Technology.
Our membrane nitrogen generators use cutting-edge nitrogen membrane technology, ideal for businesses requiring portability, lower purity, or high flow rates. These systems are compact, energy-efficient, and perfect for applications where space and flexibility are essential.
Our nitrogen generators serve a wide range of industries in Australia, including:
Switch to on-site nitrogen
For remote applications such as oil & gas plants and coal mining, Membrane technology is the ideal choice, but in certain circumstances, the PSA technology is recommended.
Our membrane nitrogen gas generators provide a continuous supply of nitrogen using proven nitrogen membrane systems that are well-suited for rugged, remote conditions such as coal mining and oil & gas applications.
As Australia’s leading provider of customised nitrogen gas generation solutions for the oil & gas and coal mining applications, membrane technology is typically the choice however we can offer both pressure swing absorption and membrane technology if it is the right fit for the application.

Food & Beverage, Metal Laser Cutting, Chemical, LABORATORY and more
For industrial applications such as food and beverage, metal laser cutting, and laboratories, PSA technology is the ideal choice.
It offers significant savings compared to traditional gas supplies, and can cost less than 10c per cubic meter. With an on site nitrogen generator, you have a continuous supply of nitrogen gas available at the purity, pressure, and flow rate you require on demand.
With our PSA (pressure swing adsorption) technology, the nitrogen purity will remain consistent over time, ensuring high-quality gas for the system’s entire lifespan meeting the unique demands of these industrial applications.
The ideal nitrogen generator for your facility depends on several factors:
If you’re looking for a compact, efficient solution, a membrane nitrogen generator may be the ideal fit—especially for medium purity, high-flow, or portable nitrogen requirements.
Our team can assess your needs and recommend the best nitrogen generator for your business.

A nitrogen generator produces nitrogen gas from compressed air through either Pressure Swing Adsorption (PSA) or membrane technology. It enables businesses to have an on-demand, high-purity nitrogen supply without the need for stored cylinders or bulk liquid nitrogen.
The cost of nitrogen generators depends on several factors, including the required purity, flow rate, and technology (PSA or membrane). Please contact us for a customised quote based on your specific requirements however typically you can expect a fast return on your investment.
A well-maintained nitrogen generator will last well over 10 years. Regular service and maintenance will help extend its lifespan further.
The output capacity of a nitrogen generator depends on its size, technology, and your facility’s requirements. Our generators are available in various capacities to suit different industrial needs.
Yes, nitrogen generators require compressed air to separate nitrogen from other gases. The compressed air is typically filtered and pressurised to meet the generator’s operating needs.
No, nitrogen itself is not a fuel for electricity generation. However, it is frequently used in industrial processes that support power generation machinery and systems.
Nitrogen generators can produce nitrogen with purity levels ranging from 95% to 99.999%, depending on the specific needs of the application, such as food preservation, pharmaceuticals, or electronics manufacturing.
Regular maintenance is required, however is a simple task that many customers prefer to carryout themselves. Generally maintenance does not require specialised knowledge and includes filter replacements and checks on system pressure and efficiency. Routine maintenance helps extend the life of the nitrogen generator and ensures optimal performance.
Yes, nitrogen generators are designed with safety in mind, eliminating many hazards associated with cylinder handling and storage. They generate nitrogen on demand and at lower pressures than stored cylinders, minimising the risk of, high-pressure incidents, and manual handling injuries.
Installation times vary depending on the system and site requirements. However, most nitrogen generators can be installed and become operational within a few days. Our team will handle the installation process to ensure everything is set up correctly.
While some nitrogen generators are suitable for outdoor use, most systems perform best in a controlled indoor environment where temperature, humidity, and contamination can be managed. Outdoor installations may require protective weather-resistant enclosures.
Industries requiring a constant supply of nitrogen, such as food and beverage, pharmaceuticals, electronics, oil and gas, coal and general manufacturing benefit significantly from on-site nitrogen generators. These cases will give the largest cost savings.
Nitrogen generators are considered environmentally friendly as they reduce emissions linked to nitrogen cylinder transport and eliminate cylinder disposal. This significantly lowers the overall environmental impact of nitrogen usage.
A membrane nitrogen generator uses nitrogen membrane technology to separate nitrogen from compressed air. It’s a low-maintenance, energy-efficient option commonly used in applications like oil and gas, food packaging, and mining where portability and medium purity levels are important.
