Atlas Copco oxygen generators use Pressure Swing Adsorption (PSA) to extract oxygen from compressed air. This equipment provides a continuous supply at 90–95% purity. Facilities reduce reliance on liquid oxygen cylinders by generating gas on-site.
J Ll Leach manages the specification and installation of these systems. Our engineers validate PSSR 2000 compliance. We verify energy performance for the service life of the unit.
PSA technology separates gas species using pressure differentials. This application isolates oxygen from compressed air via a physical process. The Zeolite Molecular Sieve (ZMS) serves as the filtration medium. ZMS traps nitrogen molecules under pressure. Oxygen passes through the sieve to the application.
The Atlas Copco OGP system follows a four-phase cycle:
Atlas Copco manufactures two primary oxygen generator ranges. J Ll Leach engineers specify the unit based on
flow profiles and purity targets.
| Feature | OGP Series (Standard Industrial) | OGP+ Series (High Efficiency) |
|---|---|---|
| Series Description | Welded steel vessels designed for industrial environments and continuous base load operations | Extruded aluminium vessels with advanced flow dynamics and tightly packed ZMS to prevent air channelling |
| Capacity | 2 – 200 Nm³/h | 3 – 30 Nm³/h (modular) |
| Efficiency | Standard industrial efficiency | High efficiency design capable of reducing feed air consumption by up to 30% depending on demand profile, correct system sizing, and feed air quality |
| Key Design Features | Robust welded steel construction for durability and continuous operation | Advanced flow design, tightly packed ZMS, Variable Cycle Saver (VCS), Elektronikon controller integration |
| Application | Base load applications where capital cost is the primary factor, including wastewater treatment and ozone generation | Variable demand applications requiring high efficiency and reduced compressed air consumption |
| Energy Saving Features | Standard operational efficiency for continuous running systems | Variable Cycle Saver (VCS) monitors buffer tank pressure and halts the cycle during low demand to reduce compressed air consumption |
An oxygen generator is only as reliable as the compressed air system feeding it. The ZMS is highly sensitive to contamination. Oil vapour and moisture will cause irreversible damage to the sieve, which can force a costly re-bedding of the unit.
J Ll Leach specifies strict adherence to ISO 8573-1 Class 1.4.1 air quality requirements for all oxygen installations.

Switching to on-site generation offers financial benefits compared to liquid oxygen (LOX) or cylinders, depending on usage volume.
Installing an oxygen generator is an engineering project requiring a structured workflow to ensure performance and safety.
Commissioning: Engineers verify oxygen purity levels. We configure dew point alarms. The team programs the Elektronikon controller for your demand profile.
Handover: The site operator receives O&M manuals. We conduct safety limit verification training.
The handover package typically includes:
Installation of oxygen systems involves strict legal duties. J Ll Leach ensures installations meet UK safety standards:
Proactive maintenance is essential to protect the ZMS life, which can exceed 40,000 hours contingent on strict moisture and oil control.
We also apply this maintenance approach to on-site nitrogen generation systems.
Atlas Copco oxygen generators replace delivered oxygen with a controlled, on-site supply—but the system is only as good as the installation and maintenance behind it.
J Ll Leach manages these systems as engineered assets to ensure cost efficiency and regulatory compliance.
