OMEGA Oxygen generators O-GEN

With the O-GEN series, you get a stable, economical and environmentally friendly oxygen supply that frees you from gas suppliers and pressure cylinders.

The generators utilise advanced PSA (Pressure Swing Adsorption) technology, in which compressed and purified air is passed through a molecular sieve. Here, oxygen is separated from nitrogen and other gases – resulting in oxygen with a purity of up to 95%, delivered directly to your facility.

How an O-GEN oxygen generator works

The O-GEN series is constructed with two molecular sieve vessels that alternately operate in adsorption and regeneration phases to ensure continuous oxygen production.
When one container produces oxygen, the other automatically regenerates by venting the retained gases.

This double-chamber system ensures a smooth gas flow, high operational reliability, and low energy consumption.
Under normal operating conditions and with correct maintenance, the molecular sieve has an almost unlimited lifespan.

Technical performance and capacities

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 the desired degree of purity.

• Operating pressure: 5–6 barg
• Oxygen purity: 90–95%
• Inlet temperature: 10–55 °C
• Dew point: down to –60 °C
• Power consumption: <60 W
• Noise level: 80 dB(A)
• Protection class: IP54 (SIEMENS PLC control)

All O-GEN generators are supplied complete with a pre-filter, outlet filter and mufflers, ensuring clean and dry process gas, free from oil and particles.

DTI A/S and OMEGA AIR

OMEGA AIR has been part of the DTI family for several years. It is a highly valued supplier with fast response times, extensive know-how and extremely competent employees.

We regularly visit the factory in Ljubljana, Slovenia, which is constantly developing.

OMEGA AIR has a large R&D department where opportunities to optimise processes are constantly being sought, rather than copying others' products.

Therefore, we are very proud of the collaboration – especially on the drying side. Here, DTI has been involved in the development of dryers for CO2 and Hydrogen.

OMEGA AIR has the complete range for the aftertreatment of compressed air, vacuum, and gas.
