Oxyboss OB-H401
2.0 ATA Hard Shell Clamshell-Form Hyperbaric Chamber
Aluminum Clamshell-Form Chamber
The shell is aircraft-grade aluminum alloy. That choice is deliberate. At 2.0 ATA and single-seat volume, you don’t need the mass of a 900 kg carbon steel room-type chamber. Aluminum in this class runs 40–50% lighter than a comparable steel shell, which means:
- 400 kg total weight — a single-seat carbon steel chamber of similar size would be roughly 800–900 kg
- Realistic to place on a properly rated ground floor without structural retrofits
- No anti-corrosion coating required
- Easier for two or three movers to bring in on rollers
Outside dimensions: 200 × 98 × 190 cm (78.7 × 38.6 × 74.8 in). Engineering reference: designed to ASME PVHO-1 (Pressure Vessels for Human Occupancy) standard family. See the ASME link in the certifications section below for the standard family.
The interior stays daylit instead of feeling like a submarine.Interior seating is a reclining electric leather sofa, adjustable from 90° (upright) to 160° (near-flat). Wipeable, sweat-resistant. Not “medical” — it’s a chair you’d sit in for an hour without thinking about.
The interior lining is anti-static. That matters because you’re breathing an oxygen-enriched atmosphere, and any spark risk in that environment is a serious safety problem.
The lining is there so the friction between clothing and interior surfaces doesn’t build up a static charge in the first place.The door is air-cushion self-locking — pneumatic, not electromagnetic. It pressure-locks during a session and doesn’t jam if the power goes out.

Safety — Passive, Mechanical, Works When the Power is Out
- Manual pressure-release valve — 30–60 second rapid depressurization, operable from inside the chamber and outside. No electricity required.
- Automatic pressure-release valve — opens if pressure exceeds the set point; keeps the chamber inside the design envelope.
- Air-cushion self-locking door — pressure-locks pneumatically, not with an electromagnetic latch. Loss of power doesn’t jam it open or shut.
- Anti-static interior lining — eliminates static charge buildup that could otherwise create ignition risk in an oxygen-enriched cabin.
In the event of a power loss, the manual vent remains fully operable from inside the cabin.
What the Factory Actually Tests Before Your Chamber Ships
- Pressure hold and leak check — the chamber is pressurized and monitored for pressure decay over time.
- Oxygen concentration calibration — sensor reading confirmed inside 90% ± 3%.
- Compressor and A/C functional test — full-load run.
- Display synchronization test — inside and outside touchscreens mirror each other correctly.
- Three-voltage power-on test — 110 V, 220 V, 240 V all confirmed at full boot.
We don’t send a paper test report with each unit. Reports are easy to fake and hard to verify. Instead, the factory records the testing of your specific unit on video and provides that footage before shipment. The video is matched to a serial number, so it isn’t a stock clip. If you want a third party present at the factory for outgoing inspection — SGS, Bureau Veritas, TÜV — we accept that too, at buyer’s expense.
Compared to what’s typical in this category — where “quality tested” is usually just a phrase in the footer — this is the specific answer to “how do I know this thing actually holds pressure?”
Certifications — Exactly What We Hold
Superhuman Chambers put it plainly in their own buyer guide: “‘Medical grade’ is a marketing phrase, not one certification.” We agree. If a seller can’t tell you exactly which certification and which authority issued it, that’s a signal.
Product positioning: the OB-H401 is a personal wellness device. Not a medical device. It does not diagnose, and is not a substitute for medical care. Talk to your doctor before you start any pressurized oxygen routine.
Delivery — DDP door-to-door, all-in
- Customs duties: paid by us
- Import clearance: handled by us
- Broker fees: paid by us
- You never get a second bill from a customs agent, port, or freight forwarder
Delivery timeline to the continental US 48 states: 35–45 days by ocean freight, plus 15–20 working days of production before that. Shipping origin: Shenzhen, China. If you’re in Alaska, Hawaii, or somewhere less mainstream, ask us — the timeline changes and we’ll quote it specifically.
Other destinations on request:
- Europe by sea: 45–55 days
- Air freight (global): 15–20 days
- Trucking within the EU: 20–30 days
Packaging: each chamber ships in a heat-treated wooden crate (fumigation-free, ISPM 15 compliant) sized 212 × 110 × 186 cm (83.5 × 43.3 × 73.2 in). Total crated weight is meaningfully more than the 400 kg bare weight — plan for crating and pallet mass on top.
Now the part most sellers hide — the last 100 feet
You have two choices, and we’d rather you know now than at delivery:
- Two or three able people plus a moving dolly — for a ground-floor room with a level path from the curb. This is doable for most single-family homes if the door and hallway are wide enough (see the site check below).
- A local rigging or moving service — for stairs, tight corners, upper floors, or long carries. In most US markets this runs a few hundred to about one thousand dollars for a single-piece move of this weight class. Get one quote before you buy, not after.
We don’t offer white-glove US delivery ourselves. We could quote it into the sticker price and call it “included,” but that’s just an extra thousand you’re paying without knowing it. Being upfront about the last 100 feet is how you get a fair total number.
Setup — no electrician, no installer
No hardwired power. No installer visit. No electrician’s certificate.If you’re placing this in a light commercial space and your local code requires a permit for the room, that’s a separate conversation with your inspector — the OB-H401 itself doesn’t require electrical modifications to the building.
Site check — will it fit in your space
Warranty and support — three years, module-level service
- 3-year warranty on the chamber and 3-in-1 oxygen source. Global — we don’t split it by region.
- Consumables not covered — oxygen masks, mattress, pillows, soft padding, seals. These are lifecycle-replacement items. We publish the replacement intervals and stock them for order.
- Modular service — when something fails, a technician replaces the affected module, not the whole chamber.
- Real-person quote turnaround — every inquiry gets a written quote from a person within one business day.
- Documentation on request: maintenance guide, certificate originals, filter and seal replacement instructions.
Who this chamber is not for
- Recent or untreated pneumothorax (collapsed lung)
- Active or recent ear or sinus infection, or recent ear or sinus surgery
- Severe sinus congestion or an inability to equalize pressure
- Advanced COPD or other uncontrolled respiratory conditions
- Uncontrolled heart failure, recent heart attack, or severe uncontrolled hypertension
- Certain medications and courses — again, your doctor is the right person to check with
Before each session (standard hyperbaric operating practice, see Ocala Wound Care & Hyperbaric Center’s pre-session guidance): no oil-based skincare, hair gel, perfume, or alcohol-based products on the body; no lighters, matches, or ignition sources inside the chamber; no smoking (smoking works against what pressurized oxygen sessions are meant to do anyway).
Also Considering the OB-H402 (Two-Person) or OB-D201 (Cylinder)?
Optional add-ons: BIBS system, 20 L concentrator upgrade for extended sessions, custom logo, custom color, extended hose kit.
- OB-H402 — two-seat shell chamber, 200 × 148 × 170 cm, 480 kg, 2.0 ATA. Same 3-in-1 source, upgraded to 20 L/min output.
- OB-D201 — two-seat cylinder-form chamber with a sliding door, 230 × 178 × 170 cm, 500 kg, 2.0 ATA.
Ask about either during your inquiry — we’ll send specs alongside the H401 quote.

Common Questions
What "hard shell" and "2.0 ATA" actually mean?
A hard shell hyperbaric chamber is a rigid, self-supporting pressure vessel — it doesn’t need air to hold its shape. That’s the whole difference from a soft chamber. Soft chambers top out around 1.3–1.5 ATA because the walls flex; hard chambers can hold 2.0 ATA and higher because the walls don’t move. See Superhuman Chambers’ hard-shell chamber breakdown for the structural comparison.
ATA stands for “atmospheres absolute.” At sea level, you’re already sitting at 1.0 ATA. Inside the OB-H401 at its top setting, the air pressure is twice that — roughly the pressure you’d feel diving 33 feet underwater. In more familiar units, 2.0 ATA is about 202.65 kPa absolute, or 29.4 psi absolute (roughly 14.7 psi above the pressure in your living room right now). For the unit conversions, see NIST’s pressure conversion tables; for clinical context see Mayo Clinic’s hyperbaric oxygen therapy overview.
A quick note on “higher is better” — it isn’t. Airvida Chambers puts it well: “A higher number usually doesn’t mean it’s better.” The right pressure depends on what you’re doing and how your body reacts, which is why the OB-H401 is adjustable from 1.1 to 2.0 ATA, not locked at the top. You control it from a touchscreen inside the chamber, and a synced screen outside so an operator can monitor from the room.
Compression is gradual, not instant:
| Set point | Time to reach |
|---|---|
| 1.3 ATA | about 5 minutes |
| 1.5 ATA | 10–12 minutes |
| 2.0 ATA | 20–25 minutes |
Numbers vary a little chamber-to-chamber based on internal volume.
Is a 2.0 ATA hard shell hyperbaric chamber the same as an HBOT chamber?
No. HBOT — Hyperbaric Oxygen Therapy — is a clinical medical treatment delivered in a licensed facility under a physician’s protocol. The OB-H401 is a personal wellness device. Same underlying physics (pressure + oxygen), different regulatory and use context.
Why aluminum instead of stainless steel?
Weight, room fit, and cost. Stainless makes sense for high-cycle clinical use where 20–25-year lifespan and full-weld repairability are the priority (see the HERO LifeCare material comparison linked in the section above).
Aluminum makes more sense for a single-seat personal chamber where placement, transport, and floor-loading matter. Both are fine at 2.0 ATA when the alloy, thickness, and welds are right.
Does the OB-H401 need a dedicated 220 V circuit like some competitor chambers?
No. The 3-in-1 source runs on 110 V, 220 V, or 240 V. Standard outlet is fine at the appropriate voltage for your region.
What about maintenance?
Weekly wipe-down of interior surfaces and view ports; monthly check of seals, filters, and hose connections; annual professional pressure-cycle inspection. We supply the maintenance guide and replacement intervals with delivery.
