HBOT Oxygen System FAQ — Common Questions for Hyperbaric Clinics

Everything you need to know about ON2's automated safety systems, real-time monitoring capabilities, and how our technology reduces human error in HBOT operations.

Installation & Setup

How much space do I need?
Just 5 feet × 5 feet for single systems, 5×10 feet for dual systems. Fits through standard doorways and requires minimal floor space in your HBOT center.
Can I put it in my equipment room?
Yes, as long as it has minimum space requirements plus adequate ventilation for proper airflow and meets safety standards for hyperbaric facilities.
How loud is it and what voltage do I need?
Only 56 dBA (quieter than normal conversation). 40 LPM units need 240V 30A outlet, 80 LPM units need 240V 50A outlet. Dual systems require separate electrical connections.
Do I need special permits for this equipment?
No permits needed for our equipment. This is plug-and-play equipment that requires no special permits or certifications. Your facility electrician provides appropriate outlet and installs ventilation fan per local codes.

Service & Support

Is shipping and installation included?
Yes, everything is included. Professional installation in under 2 hours for single systems, 3–4 hours for dual systems. We work with your HBOT center schedule for minimal disruption to patient treatments.
Will you remove my old oxygen generation equipment?
Yes. We'll disconnect your old system and connect our new ON2 system. Disposal of old equipment is customer responsibility or we will dispose for additional charges.
What maintenance is required?
Annual preventive maintenance keeps your system running optimally. Our technicians perform all maintenance during scheduled visits to minimize disruption to your HBOT treatments.
What are the next steps after my purchase?
After purchase confirmation, our service tech contacts you to confirm installation date, provide power specs in advance, discuss any delivery constraints, and confirm installation timeline for your HBOT center.

HBOT Operation

How many chambers can one system support?
40 LPM systems support up to 2 chambers, 80 LPM systems support up to 4 chambers. Dual systems provide both oxygen and air generation for maximum operational flexibility.
Do I still need to buy oxygen cylinders?
No routine oxygen purchases for daily operation. You only need backup cylinders for power outages (emergencies only).
Is the oxygen medical grade for HBOT use?
Yes. Every ON2 Aura system produces medical-grade oxygen that meets FDA pharmaceutical standards for therapeutic use, selectable up to 99% pure — the same purity standard as the cylinder and liquid oxygen a gas company delivers. Purity is selectable per patient (93% or 99%) and continuously monitored in real time, with automatic alerts and shutdown protections if levels move outside the safe range.
Is ON2 oxygen as pure as oxygen from tanks or liquid oxygen?
Yes. ON2 systems deliver selectable oxygen up to 99% purity — the same medical-grade standard as the cylinder and liquid oxygen a gas company delivers — so you no longer trade purity for convenience. On top of tank-grade purity, you also get real-time per-chamber monitoring, automatic safety controls, and on-demand generation with no deliveries.

Costs & Ownership

What are electricity costs for HBOT centers?
Very affordable. 40 LPM units: $5–8/day. 80 LPM units: $12–15/day. Dual systems: $20–25/day (varies by state electricity rates and usage patterns).
Do I own the system after 5 years? What are ongoing costs?
Yes, buyout is just $1.00 after lease term. Annual maintenance: $2,000/year (40 LPM) or $5,000/year (80 LPM). No other costs. Most HBOT centers choose new lease for latest technology.
Are there any other costs?
No additional costs expected during the 5-year term. As long as the unit is properly installed and ventilated, your lease payment covers everything for your HBOT operation.
Can I pay out my lease anytime? Are there any penalties?
You can pay out your lease after 12 months without any penalties.

Oxygen Supply & Cylinder Replacement

How do I get rid of my oxygen tanks and cylinders?
An ON2 on-site oxygen generator produces medical-grade oxygen on demand from ambient air, so your HBOT center no longer depends on high-pressure cylinders or liquid-oxygen (LOX) tanks. You keep only a small backup cylinder set for emergencies.
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 vendor's delivery window.
How can I reduce my oxygen costs?
Most HBOT centers cut oxygen spending 60–70% by replacing LOX and cylinder deliveries with on-site generation, eliminating tank rental, delivery surcharges, and hazmat fees. Typical full ROI is 18–24 months.
Is there an alternative to renting oxygen tanks?
Yes — on-site PSA oxygen generation is the alternative most HBOT centers move to. You own or lease one system instead of paying per cylinder or per fill, and oxygen is always available on demand.
What happens to my HBOT sessions if an oxygen delivery is delayed or cancelled?
On-site generation removes that risk — oxygen is produced on demand whenever the system runs. Deliveries can be delayed or cancelled, and when regional demand spikes, supply can be reprioritized so specialized clinics may be served later — which can force a center to reschedule or cancel sessions. Generating on site keeps your chambers running on your schedule, not a delivery route's.
Can I get a liquid oxygen tank approved in a shopping center or leased medical suite?
Often not. Outdoor liquid-oxygen tanks require significant setbacks and landlord approval, which is difficult in the shopping centers and multi-tenant buildings where HBOT centers want accessibility and parking. An ON2 oxygen plant is a compact indoor system that fits through any 30-inch door, so your location is no longer dictated by where a cryogenic tank can be sited.
Do I have to lock into a long-term gas contract with unpredictable pricing?
Not with on-site generation. Gas-supply arrangements can involve multi-year contracts, periodic price increases, delivery surcharges, and hazmat and demurrage fees. ON2 replaces that with one predictable cost — purchase or 5-year lease — so your oxygen supply and budget stay under your control.
Is on-site oxygen generation greener than liquid oxygen and cylinder delivery?
It can be. Producing oxygen on site from ambient air removes the recurring tanker and cylinder delivery trips that liquid-oxygen and cylinder supply require, which cuts the transport emissions, including CO₂, tied to keeping a center supplied. For centers that value sustainability, generating your own oxygen is a meaningful environmental benefit.

Safety, Fire Code & Storage

How can I reduce my fire-rated storage costs?
On-site generation produces oxygen on demand and stores very little on site, so you avoid the large bulk-oxygen inventory that drives fire-rated room, setback, and hazmat-storage requirements. Final fire-code requirements are set by your local authority (AHJ); ON2 provides equipment documentation to support your review.
How do I cut cylinder handling, storage, shipment, and delivery costs?
Generating oxygen on site removes the cylinder logistics chain entirely — no deliveries to receive, no full or empty cylinders to store and move, and no shipment or hazmat-handling charges. Staff stop spending time managing a cylinder yard.
Will on-site oxygen generation pass my fire marshal or NFPA 99 review?
Because the system stores far less oxygen than bulk supply, it reduces much of what drives fire-code requirements, and the equipment installs to local electrical and ventilation codes. ON2 supplies documentation to support your review; final approval rests with your local authority having jurisdiction (AHJ).

Medical Air & Compressors

How can I get rid of my hot, noisy air compressors?
ON2 medical air systems are built for clinical environments and replace shop-style compressors, delivering clean, dry, oil-free medical-grade air for chamber air breaks and pressurization without the noise of a standard compressor.
Is there a better source of medical air than ambient air?
Yes. Raw ambient air carries moisture, particulates, and contaminants. ON2 medical air systems filter and dry the air to medical-air quality — clean, dry, and oil-free — rather than feeding unconditioned room air to the chamber.
Can I control the humidity of the air going into the chamber?
Yes. ON2 medical air systems remove humidity and let you select how much humidity you want in the air delivered to the chamber. The air is cool and fresh, supplied by ON2's own medical air system — not a shop compressor or a third-party source.

Uptime & Reliability

What happens to my oxygen supply during a power outage?
Daily operation needs no cylinders, but ON2 recommends keeping a small backup cylinder set for power outages, and the system can be connected to your facility's backup power if required.
How long do ON2 HBOT oxygen systems last, and is there a warranty?
Every ON2 HBOT 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 units still running at 15 years. ON2 also provides a nationwide service program with preventive maintenance and 24/7 emergency support.
Can I lease the system or pay monthly instead of buying it outright?
Yes. Beyond outright purchase, ON2 offers a multi-year lease with predictable monthly payments that can bundle installation, maintenance, and service, so you can match the cost to your facility's budget. ON2 will help you compare lease-versus-buy for your center.
If one module needs service, does my whole HBOT oxygen supply go down?
No. ON2 systems use a modular design, so if one module is taken offline for service the remaining modules keep supplying oxygen at the same pressure and purity — chambers stay running and there is no need to fall back on cylinders. ON2 can replace a module without the center noticing a difference. Many single-unit systems can stop entirely if the unit fails, forcing a center back onto tanks.
What happens to my oxygen if a delivery cannot reach us — closed roads, storms, or a power outage?
Because the system generates 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 run through outages, storms, and closed roads. Centers that rely on delivered oxygen can be forced to cancel sessions when a truck cannot get through; on-site generation removes that dependency.

Choosing & Sizing Your HBOT Oxygen System

Should I buy or lease an HBOT oxygen system?
Both work — it depends on how you want to budget. Buying outright gives the lowest lifetime cost and full ownership, while a multi-year lease turns the cost into predictable monthly payments that can bundle installation, maintenance, and service. Either way you stop paying recurring liquid-oxygen or cylinder charges, and ON2 will model lease-versus-buy against your current oxygen spend so you can compare the numbers.
Liquid oxygen vs. on-site oxygen generation for an HBOT center — which is better?
Liquid oxygen (LOX) is produced off site, stored in a cryogenic tank, and refilled by tanker, so you keep paying for deliveries, rental, and evaporative loss. On-site generation produces oxygen from the air around the unit on demand — no cryogenic tank, no refills, and no delivery schedule — typically saving HBOT centers 60–70% versus liquid oxygen while removing the supply risk of a missed delivery.
What size oxygen system do I need for my HBOT chambers?
It depends on how many chambers you run and how many at the same time. ON2 air + oxygen combo systems come in 20, 40, and 80 LPM and can supply up to four chambers from one system, with the Aura Conductor™ station monitoring each chamber. ON2 sizes the system to your chamber count and treatment schedule so every chamber holds pressure and purity during back-to-back sessions.
What pressure do ON2 oxygen and medical-air plants deliver, and why does it matter?
ON2 plants deliver a steady 50 to 85 PSI — at or above the roughly 50 PSI that most medical and chamber equipment needs to operate correctly. Many cheap imported concentrators cannot hold that pressure under continuous load, which is a common reason they fall short for hyperbaric use.
Can the system scale as my HBOT center adds chambers?
Yes. ON2 systems are designed to scale — a center can start with one system and later add units in duplex or triplex configurations, so the first investment keeps working as you grow. The controls run the combined system together, so you add chamber capacity without replacing what you already own.

Chamber Monitoring & Real-Time Safety

Does ON2 work with any hyperbaric chamber brand, or do I have to buy chambers from ON2?
ON2 does not make chambers — we are the on-site oxygen and medical-air supply behind them. Our oxygen plants and medical-air plants are chamber-agnostic and work with any hyperbaric chamber manufacturer, including Perry, Sechrist, and OxyHeal. You keep the chambers you already run, and ON2 generates medical-grade oxygen and medical air on site at full line pressure, replacing cylinder and liquid-oxygen deliveries with reliable, lower-cost on-site generation.
What real-time safety and monitoring does ON2 build into its hyperbaric oxygen and medical-air supply?
ON2 continuously monitors the chamber's internal environment in real time — per-chamber pressure in ATA, oxygen concentration with an enrichment alert above 23.5% for fire safety, temperature, humidity, and optional CO / CO₂ — all on one Aura Conductor™ screen, with automatic pressure relief and automated air-break timing. The oxygen and medical air are generated on site at full line pressure, so there are no cylinder or liquid-oxygen deliveries to manage.
Are ON2 oxygen and medical-air plants reliable enough for continuous hyperbaric operations?
Yes. ON2 oxygen plants and medical-air plants are purpose-built for continuous, 24/7 facility use — not home or industrial concentrators repurposed for medical duty. They run quietly, fit through any 30-inch door with no construction, carry a 5-year warranty, and use the same medical-grade technology proven in human hospitals, with a record of more than 70 million hours of oxygen production.
Can I monitor oxygen purity inside each HBOT chamber in real time?
Yes. ON2 air + oxygen combo systems (20, 40, and 80 LPM) include the Aura Conductor™ control station, which displays the live O₂ level for every chamber in real time. Oxygen purity is selectable at 93% or 99% per patient, and an enrichment alert warns if O₂ rises above 23.5% for fire safety.
Can I monitor HBOT chamber pressure in real time?
Yes. The Aura Conductor™ shows real-time pressure in ATA for each chamber and holds the target with automatic pressure relief at the set threshold.
Can ON2 systems measure temperature and humidity in the chamber?
Yes. The Aura Conductor™ displays live temperature and humidity readings for every chamber, so staff can see the real conditions at a glance throughout each treatment.
Can I see conditions for every chamber on one screen?
Yes. The Aura Conductor™ puts pressure, temperature, humidity, O₂ level, gas selection, and air-break timing for up to 4 chambers on a single screen — one screen, every chamber — with individual flow meters per chamber.
Do ON2 HBOT systems detect carbon monoxide or carbon dioxide?
Yes, optionally. ON2 systems offer real-time CO / CO₂ gas monitoring, alongside the oxygen-enrichment alert above 23.5% O₂ for fire safety.
Can ON2 HBOT systems run air breaks automatically?
Yes. The Aura Conductor™ runs pre-set timing for automatic air breaks and includes treatment presets such as standard hyperbaric, wound care, and sports recovery.
How is ON2 different from a supplier that just drops off concentrators or tanks?
A typical concentrator or cylinder supplier delivers the equipment or gas and leaves. ON2 is integrated into the center: the oxygen and medical-air supply, real-time chamber monitoring, and safety controls all run from one Aura Conductor™ console, so staff operate and watch every chamber from a single screen. Centralizing visibility this way helps reduce human error and gives the team one place to see pressure, oxygen level, temperature, humidity, and gas readings at a glance.
