Veterinary Oxygen Systems by ON2 Systems — US-Based Manufacturer Since 1984

Medical Oxygen Generators for Veterinary Clinics

ON2 Systems manufactures medical oxygen generators specifically designed for veterinary clinics, animal hospitals, and emergency veterinary practices across the United States. Our on-site oxygen generation systems produce medical-grade oxygen — selectable up to 99% pure, the same purity standard as cylinder and liquid oxygen — for veterinary surgery, anesthesia, and critical care. With over 40 years of US-based manufacturing since 1984, ON2 Systems has installed thousands of veterinary oxygen plants nationwide, helping veterinarians eliminate expensive liquid oxygen tank deliveries and cylinder rental fees.

Medical Oxygen Plants & High Flow Systems

ON2 builds medical oxygen plants and high flow systems engineered for demanding clinical environments — not the home- or industrial-grade oxygen concentrators the market is flooded with. The Aura series — available in 10, 20, 40, and 80 LPM configurations — delivers reliable, continuous oxygen flow for veterinary surgery suites, anesthesia machines, and ICU recovery areas at a full 50 PSI of line pressure, the pressure medical equipment actually requires. Cheap imported concentrators often can't hold that pressure or flow, and home units get jerry-rigged together for facility duty they were never built for. ON2 oxygen plants are designed specifically for continuous, 24/7 facility use, with a proven record of more than 70 million hours of oxygen production. High flow systems provide critical respiratory support for large and small animals, from routine dental procedures to complex emergency surgeries.

Vet ICU Cages Oxygen Supply

ON2 veterinary oxygen systems are purpose-built to supply oxygen directly to vet ICU cages, oxygen recovery chambers, and anesthesia circuits. Our systems support multi-cage oxygen delivery with consistent flow rates, allowing veterinary staff to manage multiple patients simultaneously. Each system includes real-time oxygen purity monitoring, automatic safety shutoffs, and remote diagnostics to ensure uninterrupted patient care around the clock.

Liquid Oxygen Alternative — Cheaper Than LOX

Switching from liquid oxygen (LOX) tanks to an ON2 on-site oxygen generator saves veterinary practices up to 70% on annual oxygen costs. Liquid oxygen requires ongoing tank rental, delivery fees, hazmat handling, and storage infrastructure. ON2 medical oxygen plants eliminate all of these recurring expenses by generating oxygen directly at your facility using ambient air. Most veterinary clinics achieve full return on investment within 2–3 years, with systems designed to operate reliably for 10–15 years with minimal maintenance.

Medical Air Compressors & Gas Manifolds

In addition to oxygen generators, ON2 Systems manufactures medical air compressors and gas manifold systems for veterinary facilities. Our medical air compressors deliver clean, dry compressed air for surgical tools, ventilators, and anesthesia equipment. Gas manifold systems provide centralized gas distribution throughout your clinic, connecting oxygen generators, compressed air, and nitrogen lines to every treatment room, surgery suite, and recovery area with hospital-grade reliability.

Common questions about veterinary oxygen systems

How do I get rid of my oxygen tanks and cylinders?
An ON2 on-site oxygen generator makes medical-grade oxygen on demand from ambient air, so your clinic no longer depends on high-pressure cylinders or liquid-oxygen (LOX) tanks. You keep only a small backup cylinder set for emergencies.
Is ON2 oxygen pure enough for veterinary surgery and anesthesia?
Yes. ON2 systems produce medical-grade oxygen — selectable up to 99% pure, the same purity standard as the cylinder and liquid oxygen a gas company delivers — for surgery, anesthesia, ICU cages, and critical care. You get tank-grade purity plus real-time purity monitoring and on-demand generation, with no deliveries.
Why not just use an oxygen concentrator for my veterinary clinic?
ON2 systems are medical oxygen plants, not the small, low-flow concentrators many clinics have been let down by. They deliver a full 50 PSI of line pressure — the pressure anesthesia machines, ventilators, and multiple surgery stations actually need — with tank-grade continuous flow and oxygen selectable up to 99% pure. You get the performance of tanks without the weak-flow, low-pressure limits people associate with ordinary concentrators.
Aren't oxygen concentrators unreliable, loud, or too big for a clinic?
That reputation comes from the wrong equipment — cheap imported units and home concentrators jerry-rigged for facility use, or industrial blowers built for oil-and-gas and fish farms that sound like a tractor and break down under continuous load. ON2 oxygen plants are purpose-built for continuous, 24/7 facility use: quiet at about 56 dBA, compact enough to fit through any 30-inch door with no walls removed, backed by a 5-year warranty, built on the same medical-grade technology used in human hospitals, and proven across more than 70 million hours of oxygen production.
Does ON2 veterinary oxygen equipment meet NFPA 99 and fire code?
Yes. ON2 oxygen systems are engineered to meet NFPA 99 medical gas and fire-code requirements, with built-in oxygen-enrichment alerts and automatic safety shutoffs. Final fire-code sign-off is set by your local authority (AHJ), and ON2 provides full equipment documentation to support the review.
How do I stop my oxygen deliveries?
Because the system generates oxygen on site whenever it runs, there are no scheduled deliveries, refills, or empty-cylinder pickups — your supply no longer depends on a gas company's delivery window.
How do I get rid of cylinder rental, lease fees, and ongoing gas-company costs?
On-site generation replaces the gas company for daily use, eliminating cylinder and tank rental or lease fees, delivery charges, and hazmat surcharges. You own or lease one system instead of paying the gas company every month.
Are ON2 generators cheaper than buying oxygen from a gas company?
Yes. Most veterinary clinics save up to 70% per year by generating oxygen on site instead of buying liquid oxygen or cylinders, with full ROI typically within 2–3 years.
Do I have to sign a long-term contract or deal with gas-company price increases?
No. Gas-supply arrangements can involve multi-year contracts, periodic price increases, delivery surcharges, and hazmat and demurrage fees that are hard to predict year to year. ON2 replaces that with one predictable cost — buy, lease, or a fixed monthly subscription — so you control your oxygen supply and budget instead of depending on a gas company.
What happens to my surgeries if an oxygen delivery is late or cancelled?
With on-site generation, that risk goes away — your oxygen is made on demand whenever the system runs, so you no longer depend on a delivery truck. Deliveries can be delayed or cancelled, and when regional demand spikes, supply can be reprioritized — which is exactly when a clinic can least afford to postpone or cancel a procedure.
I'm opening in a shopping center or leased space — can I even get a liquid oxygen tank approved?
Often not. Outdoor liquid-oxygen tanks need significant setbacks and landlord approval, which is difficult in shopping centers and multi-tenant buildings where parking and accessibility matter most. An ON2 oxygen plant is a compact indoor system that fits through any 30-inch door, so you can open where you want without siting a cryogenic tank outside.
How much staff time does dealing with a gas company actually cost my clinic?
More than most clinics realize. Between ordering, receiving deliveries, handling and storing cylinders, tracking rental and demurrage fees, and managing permits and hazmat paperwork, a clinic can spend a meaningful share of staff time on gas-company logistics. On-site generation removes almost all of that so your team can focus on patients.
How can I reduce my fire-rated storage and cylinder-handling costs?
Generating oxygen on demand means very little oxygen is stored on site, which reduces the bulk-cylinder handling and the fire-rated storage requirements that come with large oxygen inventories. Final fire-code requirements are set by your local authority (AHJ); ON2 provides equipment documentation to support your review.
How many anesthesia machines or surgery stations can one ON2 oxygen generator run?
It depends on the system size. ON2 Aura generators come in 10, 20, 40, and 80 LPM, scaling from a single dental or surgery suite up to large animal hospitals running multiple anesthesia machines, ICU cages, and recovery chambers at once. ON2 sizes the system to your clinic's oxygen demand.
Are on-site oxygen generators safe for a veterinary clinic?
Yes. ON2 systems generate oxygen only as needed, so very little is stored on site, and they include real-time oxygen purity monitoring, automatic safety shutoffs, and remote diagnostics for around-the-clock reliability.
How loud are ON2 oxygen generators, and what power and space do they need to install inside a clinic?
They run quietly — about 56 dBA, roughly the level of a kitchen refrigerator — with a compact footprint and standard building power similar to a home clothes-dryer circuit, so they install inside the clinic in an equipment or utility space with adequate ventilation. Every ON2 system also comes with a 5-year warranty that includes shipping and installation.
How long do ON2 oxygen systems last, and is there a warranty?
Every ON2 oxygen system comes with a full 5-year warranty that includes shipping and installation. These are medical-grade oxygen systems — the same equipment used in human hospitals — with a typical service life of about 10 years, and many systems still running at 15 years. ON2 also provides a nationwide service program with preventive maintenance and 24/7 emergency support.
Can I rent the oxygen system or get it on a monthly subscription instead of buying?
Yes. Along with buying outright or leasing, ON2 offers veterinary clinics a simple monthly subscription that bundles the oxygen system, installation, maintenance, and service into one predictable payment with no large upfront cost. Subscription plans are available for the most common clinic sizes (10, 20, and 40 LPM).
Should I buy, lease, or subscribe to a veterinary oxygen system?
It depends on how your clinic prefers to budget. Buying outright gives the lowest lifetime cost and full ownership; a multi-year lease spreads the cost into predictable payments while you use the system; and a monthly subscription bundles the equipment, installation, maintenance, and service into one payment with no large upfront cost. All three eliminate cylinder deliveries and gas-company rental fees, and ON2 will help you compare the options for your practice.
Oxygen cylinders vs. an on-site oxygen generator — which is better for a vet clinic?
An on-site oxygen generator makes medical-grade oxygen on demand from ambient air, so you stop scheduling deliveries, storing and moving heavy cylinders, and paying cylinder rental and gas-company fees. Cylinders still make sense as a small emergency backup, but for daily use an on-site generator is lower-cost, lower-hassle, and more reliable because your supply no longer depends on a delivery truck.
What size oxygen system does my veterinary clinic need?
It comes down to how much oxygen you use at once across surgery, anesthesia, and ICU cages. ON2 Aura generators come in 10, 20, 40, and 80 LPM — a single dental or surgery suite usually fits a 10 or 20 LPM system, while multi-room practices and large or emergency animal hospitals use 40 or 80 LPM, with Duplex options for 24/7 redundancy. ON2 sizes the system to your clinic's peak demand so you are not over- or under-built.
What pressure do ON2 oxygen plants deliver, and why does it matter?
ON2 oxygen plants deliver a steady 50 to 85 PSI — at or above the roughly 50 PSI that most medical equipment, including anesthesia machines and ventilators, needs to run correctly. Many cheap imported concentrators cannot hold that pressure under continuous load, which is a common reason they fall short in a clinical setting.
If one part of the oxygen system needs service, does my whole supply go down?
No. ON2 systems use a modular design, so if one module is taken offline for service the remaining modules keep producing oxygen at the same pressure and purity — the clinic typically never notices a difference, and there is no need to fall back on cylinders. ON2 can swap a module without interrupting supply. Many single-unit systems can stop entirely if the unit fails.
What happens to my oxygen during a power outage, storm, or supply disruption?
Because the system makes oxygen on site from ambient air, you keep producing oxygen for as long as you have power — and paired with a backup generator it can keep running through outages, storms, closed roads, or delivery disruptions. Clinics that depend on delivered tanks can be forced to postpone procedures when a truck cannot reach them; on-site generation removes that dependency.
Can the oxygen system grow as my practice grows?
Yes. ON2 systems are designed to scale — a clinic can start with one system and later add units in duplex or triplex configurations, so the first investment keeps working as you expand. The controls are built to run the combined system together, so you add capacity without replacing what you already own.
Is on-site oxygen generation better for the environment?
It can be. Generating oxygen on site from ambient air removes the recurring delivery-truck trips that cylinder and liquid-oxygen supply require, which cuts the transport emissions, including CO₂, tied to keeping a facility supplied. For clinics that care about sustainability, that is a meaningful benefit of producing your own oxygen.
