Most buyers start with a cabin size and a budget. The decisions that determine whether the project works — pressure, oxygen supply, floor loading, compliance and service — are made before the purchase order.

Quick answer Specify a hyperbaric oxygen chamber in five steps. One: fix the pressure — 1.1–1.3 ATA for wellness and recovery services, 1.5 ATA for the upper end of mild therapy, 2.0–3.0 ATA only where physician supervision exists. Two: size the cabin by patient throughput, not floor space. Three: check the structure — multi-seat cabins weigh 1.8–3.0 tonnes and impose 270–300 kg/m² on the floor. Four: decide the oxygen source, because 30 L/min of 93% oxygen is a supply chain, not an accessory. Five: confirm certification (IEC 60601-1, ISO 13485, CE) and, above all, who will service the unit in year seven.

1. Start with the service you intend to sell

Three commercial models account for almost every chamber sold outside a hospital, and each one implies a different specification.

Business model	What the client buys	Specification consequence
Medical adjunct	Prescribed therapy alongside wound care, radiation oncology or orthopaedics	2.0–2.4 ATA, multi-seat or wheelchair-accessible, medical device registration, physician oversight
Wellness and recovery	50–90 minute sessions marketed on recovery, sleep, energy and general wellbeing	1.1–1.3 ATA, one to four seats, hospitality-grade interior, low noise, minimal staffing
Athletic performance	Team recovery protocols, altitude adaptation, injury return-to-play	1.3–1.5 ATA, four to six seats for throughput, robust scheduling, mobile option for away fixtures

Write the service description first, then hand it to the supplier. A chamber specified from a product catalogue rather than from a service model usually ends up either over-capable and under-used, or busy and clinically indefensible.

2. Decision one: the pressure rating

Pressure is the single specification that cannot be upgraded later. It sets what you may legally claim, who must supervise sessions, and what the chamber is worth on the second-hand market.

Rating	What it can credibly support	Typical buyer	Supervision
1.1–1.3 ATA	Wellness, recovery, relaxation, altitude comfort	Hotels, spas, gyms, residential suites	Trained operator
1.1–1.5 ATA	Upper end of mild HBOT; sports recovery protocols	Performance centres, rehabilitation clinics	Trained operator, clinician on call
1.1–2.0 ATA	Clinical HBOT for elective indications	Hospitals, wound clinics, rehab hospitals	Physician-supervised
1.1–3.0 ATA	Emergency indications: gas embolism, decompression sickness, severe CO poisoning	Emergency and diving medicine departments	Hyperbaric physician, 24/7 team

3. Decision two: seats, footprint and services

The table below reproduces LBYL’s current electric steel-cabin range. All units run on 220 V/50 Hz single-phase supply with a 93% ± 3% oxygen source, and all keep in-cabin oxygen dispersion below 25% by delivering oxygen through individual masks rather than pressurising the cabin with oxygen.

Model	Seats	Pressure (ATA)	Cabin L × W × H (mm)	Weight (kg)	O₂ flow (L/min)	Power (kW)	Noise dB(A)
LB/YC-Y1J/30	1	1.1–1.3	1360 × 800 × 1965	625	5	1.5	60
LB800-50	1	1.1–1.3	2000 × 1200 × 1900	800	10	0.9	55
LB2400-30	2	1.1–1.3	2000 × 1800 × 1900	1,100	15	1.5	55
LB/YC-Y-4	4	1.1–1.3	2000 × 3000 × 1900	1,800	20	1.8	60
LB/YC-Y-6	6	1.1–1.3 / 1.5	2200 × 4200 × 1900	2,500–3,000	30	2.1	60
LB/YC-Y-1	1	1.1–2.0	1800 × 1000 × 1750	1,100	15	1.5	60
LB/YC-Y-2	2	1.1–2.0	1800 × 1700 × 1750	1,400	20	1.8	60
3.0 ATA two-seat	2	1.1–3.0	2200 × 1700 × 1950	3,000	10	2.0	65

Two details in that table decide most site plans. First, the hull is pressure-vessel steel — Q235, Q355b or Q390b depending on rating — not a fabric bag, so the cabin is a permanent installation with real mass. Second, power draw is modest: 0.9–2.1 kW covers the chamber and its oxygen source, which means a standard 220 V circuit is usually sufficient and the air-conditioning load becomes the larger utility cost.

4. Decision three: the room, the floor and the acoustics

Floor loading is the item most often missed in early planning. Dividing cabin weight by footprint gives the distributed load: a six-seat cabin at 2,500 kg over 9.24 m² works out at about 270 kg/m², and a four-seat cabin at 1,800 kg over 6 m² at 300 kg/m². Point loads at the feet are higher still on single-seat units, where a 625 kg cabin stands on roughly 1.1 m². A structural engineer should confirm the slab before the unit is ordered — retrofitting reinforcement after delivery is expensive.

● Room size: allow clearance of at least 1 m on the door side for stretcher or wheelchair access, plus space for the oxygen source and air-conditioning unit.

● Ventilation: the room, not the cabin, is the oxygen-enriched space to ventilate; plan mechanical extract and avoid storing cylinders beside the door.

● Acoustics: cabins run at 45–65 dB(A); the compressor or oxygen generator is usually the louder neighbour, so separate the two if the room adjoins a treatment area.

● Accessibility: wheelchair models use a ramp and a wider door; confirm door widths and lift dimensions before specifying an upper-floor site.

● Climate: cabins are air-conditioned or heated as an option; in hot climates the condenser needs external air, not a sealed closet.

5. Decision four: where the oxygen comes from

A six-seat chamber drawing 30 L/min consumes 1.8 Nm³ of oxygen per hour. Over a 90-minute session that is 2.7 Nm³ — roughly a third of a standard 50-litre cylinder at 150 bar. Multiply by four cycles a day and cylinder logistics become a full-time job, which is why most multi-seat installations move to on-site generation.

Supply option	Best fit	Considerations
Cylinder manifold	Single-seat units, low utilisation, temporary sites	Lowest capital cost, highest per-session cost and handling risk
PSA generator	Small clinics with steady daytime demand	0.8–1.2 kWh per Nm³; sieve life typically 2–3 years
VSA generator	Multi-seat chambers, hotels, hospitals with 24-hour demand	0.48–0.67 kWh per Nm³; oil-free; sieve life 10 years or more; under 76 dB(A)

The distinction matters commercially. On a 1.8 Nm³/h duty, the gap between 1.0 and 0.55 kWh/Nm³ is roughly 0.8 kWh per hour of operation — small per session, meaningful across a year, and larger once a facility also supplies pipeline oxygen to wards. LBYL builds both PSA and VSA generators and integrates them with the chamber and the medical gas pipeline under one warranty, which removes the usual argument between three suppliers when purity drifts.

6. Decision five: certification and the paper trail

Ask for the documents, not the logos. A chamber destined for clinical use should carry medical electrical safety certification to IEC 60601-1, a quality system certificate to ISO 13485, and — for Europe — CE marking with the applicable directive referenced on the declaration of conformity. Multi-place pressure vessels are additionally governed by pressure-equipment rules and, where acrylic windows are used, by PVHO practice; facility design in the United States references NFPA 99.

Equally important is the operating file: a screening questionnaire, an operator training record, a maintenance log, a spare-parts list with lead times, and a named service contact. Regulators and insurers ask for exactly these five items after an incident, and they are hard to reconstruct afterwards.

7. Throughput and payback: the arithmetic buyers should run

A 90-minute session plus 20 minutes of changeover allows four cycles in an eight-hour day. A six-seat cabin therefore delivers up to 24 patient-visits daily; a single-seat unit delivers about five. Model the business on 60% utilisation rather than brochure capacity — that is what most new wellness operations actually achieve in year one.

Payback formula Monthly contribution = visits per month × net revenue per visit − (operator cost + oxygen + power + maintenance). Payback months = installed cost ÷ monthly contribution. At 60% utilisation, a six-seat unit yields roughly 430 visits a month; a single-seat unit roughly 90. Plug in your own market price before signing — the equipment cost is rarely the variable that decides the outcome.

8. Deployment formats and lifecycle service

Three deployment routes are now standard. A fixed room is the default for hospitals and clinics, with the chamber, oxygen source and air-conditioning installed as a package. A containerised unit arrives pre-assembled and is operational after power connection, which suits resorts, construction camps and sites without a plant room. A mobile trailer serves sports teams and rural outreach, where the chamber travels to the patient instead of the reverse.

Whichever route you choose, ask what happens in year seven. Consumables (filters, sieve material, mask circuits), preventive maintenance intervals, remote diagnostics and the availability of spare parts determine the real cost of ownership far more than the purchase price. A supplier that monitors the unit remotely and dispatches parts before failure is worth a premium over one that answers the phone after the season has started.

9. Twelve questions to ask any supplier

1.  What pressure ratings does this hull actually hold, and who certified it?

2.  What is the documented in-cabin oxygen concentration under normal operation?

3.  How many relief valves, manual and automatic, protect the cabin?

4.  What is the distributed floor load and the point load per foot?

5.  Which oxygen source is recommended for my duty cycle, and at what purity?

6.  Who manufactures the oxygen generator, and is it covered by the same warranty?

7.  Which certificates apply to the chamber itself — IEC 60601-1, ISO 13485, CE?

8.  What operator training is included, and how is it recorded?

9.  What are the preventive maintenance intervals and consumable costs?

10.  Is remote monitoring included, and what does it actually transmit?

11.  What is the spare-parts lead time to my country?

12.  Can you show me an installation of the same model within a day’s travel?

Frequently asked questions

How much space does a hyperbaric oxygen chamber need?

A single-seat cabin needs roughly 1.4 × 1.0 m of floor plus clearance for the door, oxygen source and air-conditioning. A six-seat cabin measures 2.2 × 4.2 m and needs a treatment room of about 20 m² to operate comfortably.

Can a chamber be installed on an upper floor?

Usually yes, if the slab is rated for 270–300 kg/m² and the lift can carry the sections. Single-seat units of 625–850 kg are far easier to place than a 3-tonne six-seat cabin.

Do I need a physician to operate a 1.3 ATA chamber?

In most jurisdictions, no — a trained operator and written screening protocol are sufficient for mild HBOT. Once you treat medical indications at 2.0 ATA and above, physician supervision is expected and often legally required.

How long does installation take?

A single-seat unit is typically operational within a day of delivery, including commissioning and operator training. Multi-seat cabins with a new oxygen plant take one to three weeks, depending on site works.

What is the service life of the chamber itself?

Steel hulls from established manufacturers are designed for 10–15 years of clinical use, with the oxygen generator’s molecular sieve, door seals and relief valves as the main consumables.
