Produce oxygen on-site
Puroxi Oxygen Generator
Produce oxygen on-site—when and where you need it. PSA technology provides a continuous supply of concentrated oxygen for properly designed Puroxi water-treatment systems.
Pressure Swing Adsorption technology
Reduce Dependence on Delivered Oxygen
The Puroxi Oxygen Generator draws in ambient air and separates oxygen from nitrogen and other gases. Depending on the selected model, operating conditions and system configuration, it can typically produce oxygen at approximately 90–95% concentration.
For suitable water-treatment systems, this concentrated oxygen can be supplied to appropriately designed nano-bubble equipment to support dissolved-oxygen improvement, oxidation and biological water-quality management.
How PSA oxygen generation works
Two Vessels. One Continuous Cycle.
Ambient air intake
Air containing approximately 21% oxygen and 78% nitrogen enters the system.
Compression & preparation
The air is compressed, filtered and prepared before entering the adsorption vessels.
Nitrogen separation
Under pressure, the zeolite molecular sieve captures most nitrogen while oxygen-rich gas passes through.
Oxygen collection
Concentrated oxygen is collected, buffered and regulated for the connected application.
Regeneration
While one vessel produces oxygen, the other depressurizes and releases captured nitrogen.
Continuous operation
The vessels alternate automatically when the system is correctly sized, installed and maintained.
Why produce oxygen on-site?

Different Functions. One Engineered Pathway.
The Oxygen Generator produces concentrated oxygen. The Puroxi Nano Bubble Nozzle introduces that oxygen into a pressurized water stream and creates extremely small bubbles with a large gas-to-water contact area.
The gas supply and water hydraulics are designed together, but they remain distinct functions. Oxygen must reach every gas port on the selected nozzle arrangement.

Safety and installation
Clean, Dry, Ventilated and Temperature-Appropriate
Install the selected generator in a suitable environment according to its equipment specifications. Concentrated oxygen requires careful handling because oxygen-enriched conditions can increase combustion risk.
Keep oils, grease, incompatible materials, open flames and ignition sources away from oxygen equipment and connections. Qualified personnel must follow applicable electrical, pressure-system, fire-safety and occupational requirements.

Understanding Always Comes Before Recommendation.
Puroxi does not select an oxygen generator from water volume alone. We review the water, treatment objective, required oxygen transfer, hydraulics and operating environment before recommending the generator, compressor, oxygen capacity, pump, controls and nozzle arrangement.
