ONYX
The AirSep Onyx PSA Oxygen Concentrator is a compact, reliable and energy-efficient solution for on-site oxygen generation. Designed specifically for reliability, low operating noise and ease of use, thousands of Onyx PSA Oxygen Generators have been used worldwide.
The Onyx can deliver oxygen at concentrations of up to 95.5%, making it suitable for a wide range of commercial, industrial, environmental and specialist applications.
Its self-contained design incorporates an integrated air compressor, meaning the unit does not require a separate external compressed-air supply in standard configurations. Simply connect the oxygen outlet to the application or oxygen distribution system, connect the power supply and set the required oxygen flow.
The AirSep Onyx uses PSA (Pressure Swing Adsorption) technology to separate oxygen from air and provide an oxygen-enriched gas supply.
The self-contained configuration combines the oxygen generation system and air compressor in a single unit, providing a convenient alternative to oxygen cylinders or externally supplied compressed-air systems.
The Onyx has been designed for dependable operation while maintaining a relatively low noise level, making it particularly attractive for applications where equipment noise and installation footprint are important considerations.
A major advantage of the AirSep Onyx is its self-contained configuration.
The generator incorporates its own air compressor, eliminating the need for a separate compressed-air system in standard installations. This can make the Onyx particularly useful where space is limited or where an existing plant-air supply is not available.
The compact design also makes the Onyx easier to integrate into existing equipment rooms, workshops, commercial premises and specialist process installations.
The Onyx has been specifically promoted for its low noise level, making it a useful choice for applications where equipment noise is an important consideration.
This can be particularly beneficial in commercial, laboratory, workshop, wellness and other environments where a quieter oxygen-generation system is preferred.
The Onyx is designed to simplify installation and operation.
For standard applications, the oxygen outlet can be connected directly to the application or oxygen distribution system, while the electrical supply is connected to a suitable grounded outlet.
Once connected, the operator can switch on the generator and set the desired oxygen flow rate.
Always follow the manufacturer's installation requirements and ensure adequate ventilation and appropriate environmental conditions for the installation.
The Onyx provides several practical advantages for organisations looking for an alternative to delivered oxygen:
For suitable applications, generating oxygen on site can provide an alternative to purchasing, storing and replacing oxygen cylinders.
An Onyx generator produces oxygen as required, potentially reducing reliance on oxygen deliveries and cylinder handling.
The suitability of on-site generation depends on the application's oxygen demand, required purity, operating hours and installation conditions.
The Onyx is designed to avoid the need for a dedicated external compressed-air system in standard configurations because the generator incorporates an air compressor.
However, the unit should be installed in a suitable, protected and adequately ventilated environment. Electrical requirements vary according to the model and configuration.
Before installation, the required oxygen flow, pressure, concentration, electrical supply and operating environment should be checked against the specification of the particular unit.
The Onyx is designed for reliable operation and straightforward use. Routine maintenance requirements will depend on the operating environment, hours of use and specific configuration.
Correct ventilation and installation are important for reliable operation. Manufacturer documentation should be followed for inspection, servicing, filter replacement and other maintenance requirements.
Published specifications vary according to the particular Onyx generation and configuration. Current AirSep/CAIRE documentation lists the Onyx as a self-contained oxygen generator producing approximately 5 LPM / 10 SCFH at 9 psig, while other Onyx documentation identifies approximately 6 LPM / 12 SCFH at the same pressure. The exact specification should therefore be confirmed for the unit being supplied.

The AirSep Onyx is suitable for a broad range of oxygen-generation applications.
The Onyx can provide oxygen feed gas for ozone-generation systems, making it suitable for applications where oxygen is required as the feed gas for an ozone generator.
On-site oxygen generation can be incorporated into suitable environmental remediation processes and other environmental applications.
Oxygen can form an important part of various water-treatment and oxidation processes. The Onyx can provide an on-site oxygen source for compatible systems.
The Onyx is also documented for fish-farming applications, where a dependable oxygen supply may be required.
Oxygen generation can be used in glass-working and glass-blowing applications where an oxygen-enriched gas supply is required.
The Onyx is suitable for selected brazing and soldering applications requiring an oxygen supply.
The Onyx has also been marketed for applications such as oxygen bars, wellness/spa environments and exercise-with-oxygen applications. Suitability depends on the intended use and applicable regulatory requirements.
The AirSep Onyx is a self-contained PSA oxygen generator designed to produce oxygen on site. It incorporates an air compressor and is intended for a wide range of commercial, environmental and specialist applications.
The Onyx is advertised as capable of delivering oxygen concentrations of up to 95.5%. Actual oxygen concentration varies according to flow rate, operating conditions and specific model.
No. The Onyx is a self-contained oxygen generator incorporating an air compressor, so a separate compressed-air supply is not normally required.
Published specifications vary by configuration. Current AirSep/CAIRE information lists the Onyx at approximately 5 LPM / 10 SCFH, while other published Onyx documentation lists approximately 6 LPM / 12 SCFH. The exact output should therefore be confirmed for the model being supplied.
The standard Onyx is published at approximately 9 psig / 62 kPa / 0.62 barg product pressure. Higher-output Onyx configurations, such as the Onyx Ultra, are published at approximately 20 psig.
The Onyx is specifically designed and marketed for its low noise level, making it suitable for applications where a quieter oxygen generator is desirable.
Yes. Ozone-generator feed gas is a documented application for AirSep oxygen generators, including the Onyx range.
Oxygen generators are used in suitable water-treatment and environmental applications, and AirSep identifies waste/water treatment among its oxygen-generator applications. The correct model should be selected according to the requirements of the individual process.
Yes. Fish farming is listed as an application for AirSep oxygen-generation equipment.
The Onyx is designed so that standard configurations do not require a special installation. The oxygen outlet is connected to the application or oxygen distribution system and the unit is connected to a suitable grounded electrical outlet. Appropriate ventilation and environmental conditions must still be provided.
The Onyx family has included Onyx, Onyx Plus and Onyx Ultra configurations. These provide different oxygen flow and pressure characteristics, allowing the system to be selected according to application requirements.
