Oxyboss OB-H402
Two-Person Hard Shell Hyperbaric Chamber
Built for a Two-Person Session
- At home, for a couple or a parent and a teenage child. One cabinet, two seats, a single install, a single warranty. The same hardware a solo user would buy, with the second seat added.
- For a caregiver and a client. A spouse, carer or trainer stays inside through the session — eye contact, intercom, and the ability to pause at any time without leaving the room.
- In a studio with throughput goals. Two paying guests per session instead of one, same session length, same operator time. If the room runs six slots a day, the second seat changes the math on how a studio pays for itself.

What a Session Looks Like
- Pressurization — 10-15 minutes. The cabin fills with compressed air up to 2.0 ATA. Occupants put on nasal cannulas or masks; both ears equalize with slow swallowing or a gentle Valsalva.
- Steady state — 60–90 minutes. Pressure holds. Each occupant breathes 90% ± 3% oxygen at 10 L/min through their own mask. The cabin itself stays near room-air oxygen concentration, which is the structural reason the 24% in-cabin alarm matters.
- Depressurization — about 10 minutes. The system vents in a controlled curve to ambient.
- Door release. Once pressure reads ambient, the door releases from inside or outside manually.
- Between sessions — 20–30 minutes. The cabin airs out, surfaces wipe down, filters stay clean, and the oxygen module cools.
Single-session guideline: up to 2 hours at steady pressure. Daily throughput depends on the oxygen module, not on the chamber itself.
The 2.0 ATA ceiling is the same pressure range the Undersea & Hyperbaric Medical Society’s HBO Indications, 14th Edition describes for clinical hyperbaric settings. The OB-H402 is a personal wellness product, not a clinical device — it reaches that pressure because 2.0 ATA is the design ceiling for a hard-shell civilian chamber, not because the chamber plays any clinical role.
Safety without a Power Source
- Manual mechanical relief valve, inside and outside. Occupants can start a controlled vent from inside the cabin; an operator can do the same from outside. No power needed.
- Automatic overpressure relief. Opens on its own if cabin pressure rises past the setpoint, releases ≈ 3 kPa, and resets. Independent of the digital controller.
- Pressure-assisted door seal. The door seal is pressed tighter by cabin pressure itself — higher pressure, tighter seal — so a loss of control power does not create a leak path.
- Door release. Once pressure reads ambient, the door opens manually from either side.
We follow the FDA’s reminder that hyperbaric oxygen chambers should be operated per the manufacturer’s written instructions — see the FDA Safety Communication on safe use of hyperbaric oxygen therapy devices (reposted by UHMS). The manual that ships with the chamber mirrors that guidance, including the recommendation that occupants wear hyperbaric-compatible attire (close-fitting cotton; no synthetic fleece).
Install, Power, and Shipping
Warranty and Support
- 3-year warranty on the hard-shell chamber and on the 3-in-1 oxygen source. Consumables and normal-wear parts are excluded.
- Covered repairs: faulty non-consumable parts replaced at no cost. Air-freight on the replacement part is on Oxyboss during the warranty period.
- Out of warranty: replacement parts remain available at factory cost; technical support continues for the life of the unit.
- Fault response: confirmation of the issue within 48 hours of photos or video reaching us; typical dispatch of the replacement part within 3–5 days of fault confirmation. 24/7 online technical support sits behind that.
- Training: free 1-on-1 online video onboarding, user manual, and operation videos. A training certificate is issued on completion.

Common Questions
Can two adults really fit in a two-person chamber, or is it just a wider single-person chamber?
Two full-size seats on one electric sofa, inside an interior sized at 200 × 148 cm. Each seat has its own mask line at 10 L/min — the same per-person oxygen flow a single-seat Oxyboss chamber delivers.
Is this chamber a medical device?
No. The OB-H402 is a general wellness product. It does not carry an FDA 510(k) clearance and is not marketed as treatment for any condition. Clinical hyperbaric settings are a separate category of device with a different regulatory pathway.
Where can the chamber be viewed and tested?
If you can visit China, the showroom in Shenzhen is open by appointment. For anywhere else, we send session walkthroughs, interior videos, and a live video call with the engineering team — ingress, controls, seating, and exterior connections included.
Is a trained operator required for commercial use?
A dedicated operator is not required. The identical touch panels inside and outside let a trained user run the session on their own. Studios typically still station a staff member nearby for the first few sessions and for guest reassurance.
Do you ship a 2.0 ATA hyperbaric chamber for sale directly from the factory?
Yes. We are the manufacturer. The 2.0 ATA chamber ships from Shenzhen on DDP terms — duties and clearance on our side, final-mile handling on yours. Pricing goes out by quote; one of our team replies to a quote request within one business day.
What is included in the price, and what is not?
Included: the chamber, the 3-in-1 oxygen module, inside/outside touch screens, hoses, standard masks, interior padding, and the electric double sofa. Not included: optional BIBS mask upgrade, extended warranty beyond three years, and final-mile handling into the room.
What happens if something breaks after the chamber lands in another country?
Photos or video on first contact. Remote troubleshooting within 48 hours. If a part needs swapping, the replacement part ships via air freight — paid by Oxyboss within the warranty window — and 24/7 support sits with the engineering team through the fix.
Can I bring a phone or tablet into the chamber?
Low-voltage personal electronics (under 24 V) are fine. Open-flame items and lighters are not.
