An oxygen generator concentrates oxygen from compressed air to deliver a dependable, on-site supply with controlled purity, flow, and pressure. Most industrial and laboratory systems use the PSA technology with zeolite. On-site O₂ reduces manual handling, stabilizes operating cost, and simplifies compliance by enabling continuous monitoring and documented performance.
An PSA oxygen generator is a system that produces high-purity oxygen directly from compressed atmospheric air. While ambient air contains around 21% oxygen and 78% nitrogen, the generator separates and removes the nitrogen, delivering a clean, concentrated flow of oxygen. FLAIRMO oxygen generators are built to provide oxygen with purities ranging from 90% to 95%, on-site. This is made possible through PSA (Pressure Swing Adsorption) technology, which enables consistent, efficient on-site oxygen production.
Pressure Swing Adsorption (PSA) is the core technology used to separate oxygen from nitrogen in ambient air. Inside the generator, this separation takes place within specialized towers filled with zeolite granular. This granular material acts as a high-tech filter that adsorbs nitrogen molecules while allowing high-purity oxygen to pass through for your application.
To provide a continuous supply of oxygen, the system utilizes a regeneration phase. PSA generators are built with two towers that work in tandem: while one tower is under pressure and actively adsorbing nitrogen, the second tower is “depressurizing.” During this shift, the trapped nitrogen is released from the zeolite and vented out of the system. This cleaning cycle ensures the zeolite is refreshed and ready to start the next adsorption phase. The number and size of these towers are customized based on your required flow rate and purity levels, ensuring the system is perfectly scaled to your needs. By constantly “swinging” between these towers, the generator delivers a steady, cost-effective, and reliable flow of on-site oxygen, with purities ranging from 90-95%.
At FLAIRMO, we provide two distinct ways to integrate on-site oxygen generation into your facility. The ideal configuration depends on your available floor space and whether you already possess a compressed air infrastructure. Below, we outline our two core product lines – Internal Air Supply and External Air Supply – to help you identify the most efficient system for your specific needs.
For facilities where space is at a premium, our internal air supply models offer a complete, plug-and-play O2 generator in a single cabinet. This compact solution features a built-in oil-free compressor, advanced drying, and filtration integrated directly into the unit, removing the need for an expensive or complex installation.
Proudly standing as one of the most space-efficient solutions on the market, these systems deliver a reliable flow range from 5 to 10 l/min. This makes them the ideal choice for work places that require a steady supply of high-purity oxygen without the massive footprint of traditional setups. While the generator is entirely self-contained, it can be seamlessly paired with an external holding tank if your application requires additional storage capacity to handle peak demands.
Our external air supply oxygen line is a modular, high-capacity solution designed for maximum flexibility. A complete FLAIRMO setup typically includes a high-performance oil-free compressor, a specialized air dryer, precision filtration, and the PSA oxygen generator itself. By keeping these components separate, we can offer flow rates ranging from 5 to 40 l/min, all while maintaining an exceptionally small footprint for the generator unit, making it easy to integrate into your existing facility.
If your facility is already equipped with a compressed air network, you can connect our oxygen generator directly to your current system. To protect the sensitive zeolite molecular sieve inside the generator, your air supply must meet strict ISO 8573-1: Class 2.4.1 standards
One of the most common questions when considering an oxygen generator is: What kind of savings can I expect? The answer depends on your current oxygen supply method. If you’re relying on bottled and have a steady or high consumption, switching to on-site generation can result in significant cost reductions, many businesses see a return on investment within just a few months.
With bottled oxygen, you’re not only paying per unit, but also facing ongoing expenses such as rental fees, ADR (Dangerous Goods) handling, and frequent delivery costs. These recurring charges quickly add up. By comparison, an oxygen generator requires a one-time upfront investment, with low annual operating costs, mainly limited to power usage and basic maintenance.
In simple terms, most users experience a return on their investment (ROI) within 2 to 18 months. The more detailed answer depends on your specific setup, oxygen demand, and operational requirements, but for many, the long-term savings and independence are well worth the switch. We’ve made a Return On Investment calculator. Try it on the link below.
On-site oxygen generation is a game-changer for industries requiring high-purity gas without the logistics of traditional deliveries. At FLAIRMO, we specialize in providing reliable oxygen solutions tailored for the demanding environments of aquaculture and water treatment.
In aquaculture, maintaining stable dissolved oxygen levels is vital for fish welfare and growth. Our generators support RAS systems and raceways during critical feeding peaks and provide essential emergency backup. By producing oxygen on-site, you can increase stocking densities and eliminate the risks and costs associated with cylinder handling.
For water treatment, high-purity oxygen is the key to efficient ozonation. It ensures consistent disinfection with fewer by-products compared to using ambient air. Whether for small plants or large-scale facilities, our systems deliver a dependable, on-demand supply that significantly lowers operating costs and removes your dependency on bottled oxygen.
To get the most out of your FLAIRMO system, it all starts with the right data. By sharing your specific needs for purity, flow, and pressure, we can accurately size your generator and select the ideal compressor for the job. We often recommend a slightly more robust air treatment chain; it is a cost-effective way to safeguard your gas purity and significantly extend the life of your generator’s internal components.
At FLAIRMO, we believe your oxygen supply should be a utility you can count on, not a maintenance burden. Our oxygen generators are engineered with a user-friendly, open-access design; simply unscrew the front panel to reach all internal components instantly. From there, routine upkeep is straightforward – just follow the clear, visual steps outlined in your service manual. Our support model is built to ensure your operation never skips a beat, no matter where you are located. We provide expert technical guidance via phone and email, backed by rapid troubleshooting to resolve any performance queries immediately. To eliminate long wait times, we maintain a full inventory of critical service kits and components ready for same-day shipping. This combination of easy on-site access and responsive remote support ensures your FLAIRMO oxygen system remains a reliable, high-purity asset for years to come.
Switching to a FLAIRMO on-site oxygen generator replaces the burden of gas logistics with a reliable, high-performance utility. By tailoring the purity, flow, and pressure to your facility, we ensure long-term stability with transparent costs and an end to delivery delays. If you are currently comparing cylinders or bulk liquid to on-site generation, the best starting point is mapping out your actual usage and quality requirements. Share these basics with us, and our specialists will design a right-sized solution for you – complete with commissioning support and a clear maintenance plan. Let’s build a system that ensures your production never has to wait for a delivery truck again.
