Oxyboss OB-H301
2.0 ATA Single Person Mini Hyperbaric Chamber
The OB-H301 mini hyperbaric chamber combines a rugged pressure vessel, a space-saving footprint, and a fully integrated oxygen source in one seated single person hyperbaric chamber built for home wellness rooms, boutique studios, and busy recovery centers.
Adjustable operating pressure from 1.1 to 2.0 ATA. Third-generation 3-in-1 oxygen source with concentrator, air compressor, and air conditioner in a single cabinet. Sync touchscreens inside and outside the chamber, so the user runs the session without an outside operator.
- 3-in-1 integrated oxygen source — one cabinet, one power cord
- 1.1–2.0 ATA operating pressure, adjustable
- Optional BIBS for advanced protocols
- Front-opening or side-opening door, chosen at order
- DDP door-to-door shipping — no surprise customs bill
- 3-year global warranty on the chamber and the oxygen source

Most home hyperbaric chambers on the market — including the ones people compare us with — ship as a chamber only. The oxygen concentrator, the air compressor, and the air conditioner are three separate boxes you're expected to source, plumb, and maintain yourself. The OB-H301 skips all of that. Compression, oxygen generation, and interior climate control all live in one cabinet — Oxyboss's third-generation 3-in-1 oxygen source, engineered for continuous operation.

Fully Modular Internals
Every core module inside the cabinet — PSA sieve, compressor, condenser, control board — is designed to be pulled and swapped individually. A single component failure doesn't mean stripping the whole system. It means one part, one job.
Single-hose Plumbing
All lines between the oxygen source and the chamber are bundled into one integrated cable path. Setup is one connection. The room stays clean. No spaghetti of hoses across the floor.
0.42 m² Footprint
The 3-in-1 cabinet measures 930 × 450 × 920 mm — roughly the footprint of a small filing cabinet. Compared with the 0.9–1.2 m² of floor space that three separate units usually take up, the OB-H301 gives back most of a square meter. That matters when the chamber is going in a spare bedroom, a wellness studio corner, or a treatment room already crowded with other equipment.
PSA Molecular Sieve
Pressure swing adsorption delivers 90% ± 3% oxygen concentration at 10 L/min, continuously, for the entire session length. No cylinders to swap, no medical gas contract, no delivery schedule.
Oil-free Compressor
No oil vapor in the airflow path. Long-term maintenance is filter changes and seal inspections, nothing else.
Integrated Water-cooled Climate Control
Precise interior temperature control for longer sessions, especially in warm rooms.
Sound Damping
Six-sided sound-damping panels on the cabinet walls, plus vibration isolation springs under the compressor and concentrator bases. Outside the cabinet, 1 meter away, sound level is ≤ 60 dB(A) — about the volume of a normal conversation. Inside the chamber during a session, 45–48 dB(A) — quieter than a dishwasher.
1.4 m² projected footprint
The chamber measures 140 × 100 × 190 cm — about the floor space of a single-person massage chair, and low enough to slip into a room corner or a spa treatment nook without renovation. This is what makes the OB-H301 a genuine small hyperbaric chamber for tight spaces, not a marketing label.
Built for continuous operation
The pressure vessel is Q235 industrial-grade carbon steel — chosen because it holds shape under repeated pressurization cycles day after day. In a home the chamber may run once a day; in a wellness studio it may run six times. The material spec is the same either way.
Front-opening or side-opening door
Two door orientations to fit different room layouts and use patterns. Choose at order.
Modular PA fabric sofa
The interior seat is upholstered in polyamide fabric — sweat-resistant, oil-resistant, alcohol-tolerant for cleaning between sessions. The cushions are modular, so a single worn panel can be swapped without replacing the whole seat.
Anti-static interior lining
The interior walls are lined with anti-static fiber to dissipate any static charge from clothing or movement — one of the mechanisms the FDA safety communication of August 2025 flagged as a fire risk factor in poorly designed chambers. (FDA safety communication on hyperbaric chamber fires)
Large viewing windows
The chamber has multiple external windows, so the interior stays bright and open. Users who worry about claustrophobia usually find the sit-down format significantly easier than a capsule.
Compact Chamber, No Compromise on The Experience
Chamber design decides both structural stability and how the user actually feels during a session. The OB-H301 is engineered around three principles: flexible deployment, straightforward daily operation, and long-run mechanical stability. It's compact — but nothing about the interior experience is scaled down to get there.
Mirrored Controls, Inside And Outside
The OB-H301 has two synchronized 10-inch touchscreens — one mounted inside the chamber next to the user, one on the outside of the 3-in-1 cabinet. Both screens display the same real-time information and accept the same inputs:
- Pressure setpoint and current pressure
- Session timer
- Interior temperature
- Oxygen concentration
- Alarm status
Every control lives on one screen. No nested menus, no submenu diving to change a setting. Training time is measured in minutes, not sessions.
The chamber also ships with a two-way intercom between the interior and exterior — used when someone else is running the equipment or when the user simply wants to talk without opening the door.
The practical outcome is that the user can operate a session solo. No dedicated technician needed on the outside.
Passive Safety Design
Automatic pressure relief valve
Pure mechanical spring construction. When chamber pressure exceeds the setpoint, the valve opens and bleeds pressure until equilibrium is restored, then closes. The cycle repeats throughout the session — that's how the chamber holds a stable target pressure.
Visual Pressure Monitoring System
A mechanical gauge displays pressure in real time, with accuracy up to 0.01 ATA.

Manual pressure regulator
A tactile fine-adjustment knob for user-controlled pressure changes during the session.
Automatic Pressure Relief Mechanism
Mechanical activation is triggered automatically in the event of overpressure, without relying on electrical signals.
Emergency pressure release
A single-action release opens a large-diameter vent for rapid depressurization in 30–60 seconds. Both interior and exterior control locations.
Manual Pressure Relief Control
Pressure relief can be manually activated from both inside and outside at any time.
Self-locking pressure door
The chamber door uses interior pressure to hold itself sealed — the higher the pressure, the tighter the seal. When pressure fully vents to ambient, the door releases and can be opened by hand from either side.
Emergency Pressure Relief
Manually activated, with pressure relief completed within 30 seconds.
Continuous chamber oxygen monitoring
Both touchscreens display real-time interior oxygen concentration. If interior oxygen ever exceeds 24%, the system automatically shuts off oxygen delivery and continues ventilation.
Dual Inside-and-Outside Control Mechanism
Either side can independently complete all operations.
Fire-retardant, anti-static interior
No exposed electrical components inside the chamber. Anti-static flooring throughout.
Multi-Layer Sealing Structure
YKK zipper with multiple sealing layers and a redundant path design.

Fire-retardant, anti-static interior
No exposed electrical components inside the chamber. Anti-static flooring throughout.
The chamber pressurizes with compressed air, not oxygen — chamber interior air stays close to normal room oxygen concentration. The 90% ± 3% oxygen flows through the mask or nasal cannula only, delivered directly to the user's breathing zone. This is the single most important safety design difference between a well-engineered mild hyperbaric chamber and the incident cases the FDA has reported.

Ideal Use Cases
The OB-H301 is designed for buyers who need a single person hyperbaric chamber that:
- Fits into a spare bedroom, home office, or wellness room without renovation
- Runs on standard 110V / 220V / 240V outlets — no special electrical work
- Sits up rather than lies down — for reading, tablet use, or working during a session
- Handles daily use over 8–10 years of expected service life
- Works for both a private home and a small commercial wellness or recovery studio
Common deployment scenarios: home wellness rooms, boutique recovery studios, SPA and salon back-of-house, gym add-on services, dealer showrooms.
If you need a two-person seat, the H402 double shell or D201 cylinder are the closer fit. If you need to fold the chamber away between uses, look at the S158 or S159 soft-shell instead.
