Multi-person hyperbaric, minus the fuss: what buyers really ask me

If you’re sizing up a Multi Person Hyperbaric Chamber for a wellness center, clinic, or a high-performance gym, you’re not alone. Demand has quietly shifted from single-occupancy “capsules” to roomy, supervised multi-seat systems that are safer to operate, easier to monetize, and—surprisingly—more comfortable for anxious first-timers.

The model I’ve seen gaining traction lately is the Multiple People Micro Large Space Hyperbaric Oxygen Therapy Chamber, assembled in Hebei (888 Kaiyuan Road, Jizhou District, Hengshui City). It’s a mild-pressure, oxygen-enriched room that balances clinical discipline with spa-like touches. To be honest, that mix matters more than brochures admit.

Why multi-person now?

Trends point to shared sessions in wellness chains, sports recovery labs, neuro-rehab clinics, and even corporate vitality programs. Operators like that a supervisor can manage several guests at once, while customers—many say this—feel calmer in a brighter, larger space. The Multi Person Hyperbaric Chamber format also simplifies throughput and scheduling.

Indicative specifications (real-world use may vary)

Capacity	4–8 seats (wheelchair option)
Operating pressure	≈1.3–1.5 ATA (mild HBOT range)
Oxygen delivery	93% ±3% via medical O2 concentrators; mask or hood
Shell / interior	Powder-coated steel shell; SUS304 liner; panoramic windows
Safety	Dual over-pressure valves, O2 monitoring, intercom, UPS backup
Noise	≈58–62 dB(A) in chamber at 1.5 ATA
Controls	PLC touch panel + manual overrides
Power	AC 220–240 V, 50/60 Hz, ≈2.5–4.0 kW (build-dependent)
Standards (target)	ASME PVHO-1, ISO 13485 QMS, IEC 60601-1/-1-2, NFPA 99 oxygen safety

How it’s built (materials, methods, testing)

Materials: pressure-rated steel plate with internal stainless trim; fire-retardant seating; oxygen-cleaned tubing (CGA G-4.1). Methods: ASME Section IX–qualified welding; powder-coat cure; oxygen cleaning and verification. Testing: NDT (UT/RT per ASTM), hydrostatic to ≈1.5× MAWP, functional pressurization cycles, oxygen leak checks

Factory sample log (last run I reviewed): 1.45 ATA hold 60 min; pressure drift ≈0.1%; intercom clarity 4/5 at full compressor load.

Where it fits

• Sports recovery labs rotating 4–6 athletes per hour
• Neuro and mobility rehab with caregiver supervision
• Wellness studios bundling breathwork + mild HBOT
• Corporate vitality rooms (quiet, device-friendly)

Vendor snapshot (what buyers compare)

Vendor	Pressure	Seats	Certs (typ.)	Lead time	Notes
StoreOxygen (Hebei)	1.3–1.5 ATA	4–8	ISO 13485, IEC 60601, PVHO-1 (target)	≈6–10 weeks	Good customization; value pricing
Vendor S (domestic)	1.5 ATA	6	CE MDR	8–12 weeks	Higher price; strong documentation
Vendor T (acrylic dome)	1.3 ATA	2–4	IEC 60601-1-2	4–6 weeks	Great visibility; fewer seats

Customization that actually matters

Layout (bench vs. recliners), wheelchair ramp, medical pass‑throughs, antimicrobial upholstery, branding, infotainment, and, yes, extra windows. Many customers say the intercom and lighting presets are the small features that win them.

Field notes and mini case studies

A Midwest physiotherapy chain replaced three single units with one Multi Person Hyperbaric Chamber; throughput rose ≈40% with a single attendant. An eSports training house in Seoul customized for quieter compressors; subjective fatigue scores (their internal metric) improved after two weeks. Feedback repeats: “spacious,” “less claustrophobic,” “sessions feel shorter.”

Compliance and safe operations

Ask for oxygen-cleaning certificates, pressure test records, and operator training aligned to NFPA 99 and UHMS guidance. It seems obvious, but verify maintenance intervals and have a written emergency depressurization protocol. For clinics, document device integration under your ISO 13485 QMS (or equivalent).
