A nitrogen generator is a machine that separates nitrogen from compressed air, which consists of 78% N2 and 21% O2.
A gas generator is the easiest, most flexible, cost-efficient and sustainable way of obtaining your own nitrogen supply.
On-site generation offers convincing benefits compared to liquid or gaseous N2 deliveries.
1. Cost efficiency
Producing your own nitrogen with the purity you need allows you to significantly reduce your cost
of gas
2. Sustainability
Eliminate the transport emissions that nitrogen deliveries generate. In addition, Pneumatech’s
on-site generation solutions are super efficient, minimizing your energy use and your environmental footprint.
3. A reliable nitrogen supply
No need to count on external vendors. On-site generation gives you complete control over
your nitrogen supply.
4. No logistics
Say goodbye to always monitoring your N2 supply, working with vendors, and tracking
and handling deliveries.
To produce your own nitrogen, all you need is a compressor and a nitrogen generator. That’s because air consists of 78% nitrogen and 21% oxygen. When you feed compressed air into a nitrogen generator, it separates the N2 from the O2. There are two main technologies to produce nitrogen:
PSA technology
Utilizing PSA technology, Pressure Swing Adsorption (PSA) effectively isolates nitrogen from compressed
air by utilizing adsorbent materials. By passing the air through a vessel containing Carbon Molecular Sieves (CMS), the oxygen is captured,
allowing only nitrogen of up to 99.999% purity to exit. PSA generators are well-suited for applications requiring high-flow and high-purity
nitrogen.
Membrane technology
Membrane technology is a very simple, reliable and continuous N2 production method.
Compressed air is pushed through hollow polymer membranes. The oxygen in the air escapes through the fiber walls and permeates into the
atmosphere. This leaves quality nitrogen with a purity between 95% and 99.5% at the generator outlet.

Discover the inner workings, versatile applications, and numerous benefits of an N2 generator. This revolutionary machine effectively separates nitrogen from compressed air, comprised of 78% N2 and 21% O2. A gas generator stands out as the easiest, most flexible, and economically viable method for securing your own nitrogen supply. Elevate your professional approach and embrace the efficiency and sustainability offered by on-site nitrogen generation, exclusively available in New Zealand.
Pneumatech’s PMNG range of nitrogen generators utilizes proprietary membrane separation technology. Membrane generators are an excellent choice in low (90%) to medium (99,5%) purity applications such as tire inflation, fire prevention, tank blanketing and pipeline drying. Nitrogen pressures can go up to 12 bar (g) without the need for an additional booster.
Engineered for simplicity, durability and ease of use make the PMNG what we believe to be the most user friendly unit in the market. All pre-filters and controls are included inside the canopy.
The PPNG series is Pneumatech’s premium on-site nitrogen solution for low to high flows, with best-in-class performance and the most complete scope of supply.
The generator has outstanding air factors at full load thanks to the use of highly efficient Carbon Molecular Sieves (CMS) and back-flow pressurization.
The air consumption is also optimized at reduced nitrogen flow or pressure demands, thanks to the advanced energy saving algorithm, which automatically adjusts the cycle times of the generator.
The control and monitoring capabilities of the PPNG series are truly impressive.
