Generators for the production of nitrogen (N₂) and oxygen (O₂) make it possible to produce gas directly on site and ensure a stable and reliable supply. Below you will find N₂ and O₂ generators as well as nitrogen systems for various industrial needs, where continuous operation and high gas purity are required.
At Dansk Trykluft Industri, we supply N₂ and O₂ generators from recognized manufacturers such as Drytec and Omega Air. Our generators produce nitrogen (N₂) and oxygen (O₂) directly from the surrounding air – safely, economically, and environmentally friendly. Using PSA technology (Pressure Swing Adsorption), the gases are extracted from compressed air from a compressed air system or compressor, which separates oxygen and nitrogen with high precision. The result is pure gas on-site, without the need for cylinders, delivery, or external supply. This means lower operating costs, constant availability, and full control over quality.
Nitrogen generators (N₂) – flexible and efficient gas production
The pure nitrogen is then directed to the process system via a buffer tank, while the excess air is discharged.
Advantages of N₂ generators:
The Drytec PSA Nitrogen Generator is built with two adsorption vessels that operate alternately to ensure continuous gas production.
This ensures stable operation, low energy consumption, and high reliability – ideal for industries as:
The systems are available as modular and twin tower solutions with integrated flow meter, oxygen sensor, and carbon filter, ensuring correct gas purity and continuous monitoring.
Our O-GEN oxygen generators from Omega Air are based on the same PSA principle as the nitrogen systems. Here, a molecular sieve (13X type) is used to separate oxygen from the air, while the other gases are discharged.
Typical applications:
The generators deliver oxygen with purity levels of up to 95% at an operating pressure of 5–6 bar, and can operate fully automatically via SIEMENS PLC control with WebControl.
With proper maintenance, the molecular sieve has an almost unlimited lifespan, and the generators require only minimal service.

Producing nitrogen and oxygen directly on site provides a wide range of advantages compared to cylinder or tank supply:
Both nitrogen and oxygen generators can be connected directly to existing compressed air systems and integrated with monitoring, drying systems, filtration, and other after-treatment of compressed air for maximum efficiency.

Air At Dansk Trykluft Industri, we supply oxygen generators (O₂ generators) from Omega Air, which produce pure oxygen directly from compressed air.
With the O-GEN series, you get a stable, economical, and environmentally friendly oxygen supply that makes you independent of gas suppliers and cylinders.
The generators use advanced PSA technology (Pressure Swing Adsorption), where compressed and purified air is passed through a molecular sieve.
Here, oxygen is separated from nitrogen and other gases – and the result is oxygen with a purity level of up to 95%, delivered directly to your system.
The O-GEN series is built with two molecular sieve vessels that operate alternately in adsorption and regeneration phases to ensure continuous oxygen production. When one vessel produces oxygen, the other is automatically regenerated by venting the retained gases.
This dual-chamber system ensures a steady gas flow, high operational reliability, and low energy consumption. Under normal operating conditions and with proper maintenance, the molecular sieve has an almost unlimited lifespan.
The O-GEN series covers models from O-GEN 1 to O-GEN 100, with flow rates from 1.1 m³/h to over 100 m³/h depending on the model and desired purity level.
All O-GEN generators are supplied complete with pre-filter, outlet filter, and silencers, ensuring clean and dry process gas, free of oil and particles – which can be documented through air quality analysis.
The O-GEN generators are supplied with SIEMENS PLC control and WebControl, providing fully automatic operation, monitoring, and remote access.
Additionally, the systems can be equipped with:
This provides maximum control over gas production, quality, and energy consumption, regardless of whether the system is used in process, laboratory, or production environments.
The O-GEN series can be adapted to a wide range of applications where on-site oxygen production provides significant operational and economic advantages:
On-site production of these gases is becoming increasingly popular, as the profitability is very good compared to purchasing the gas in cylinders or cryogenic tanks.
