HBOT YF-4003 (ATLAS)
YF-4003 (ATLAS) 4-Person Hard-Shell Hyperbaric Oxygen Chamber
- Elliptical/round chamber design: evenly distributes force and resists deformation under sustained high pressure
- High-pressure protection: a password is required when the set pressure is ≥1.6 ATA to prevent accidental operation
- Water-cooled air conditioning: no refrigerant charging is required, making long-term use safer and easier
- Two-way internal/external intercom: in-chamber and external communication units
- Exhaust mode: the safety valve continuously exhausts while air continues to enter, maintaining high air circulation and freshness inside the chamber
- Customization: OEM/ODM support for chamber shell, floor, carpet, interior and seat colors
YF4003 product overview
A multi-person platform designed for coordinated operation
YF-4003 (ATLAS) is a rounded 4 person hyperbaric chamber for wellness centers, spas, and hospitality spaces. The 3150 × 1875 × 1950 mm body provides 40 L/min oxygen flow, ≤10-minute pressurization, and up to 2.0 ATA. Use it as a multiplace hyperbaric chamber, hyperbaric chamber for wellness center, or hyperbaric chamber for spa. Nose breathing and face-mask upgrades are available.

Gas circulation and noise control
Continuous ventilation refreshes cabin air, helps keep carbon dioxide low and controls operating noise at about 50 dB.
Custom floor materials and colours
Carpet, stone-look panels and other floor finishes can be selected and coordinated with the seats, walls and interior palette.
Round observation window
A round observation window helps distribute pressure evenly and widens the view for clear external monitoring.
Spacious cabin interior
The rounded cabin and open layout make entry, observation and mobility easier, including for multi-user or wheelchair scenarios.
Application scenes
Six application scenes are arranged in two rows of three cards.
Our materials
Core materials are selected around pressure-bearing performance, everyday durability and a clean project finish.
Door
20-25 mm | Panel material: PC boardA reinforced door panel supports a stable seal and repeated daily access.
Window
20-25 mm | Panel material: PC boardThe viewing panel balances visibility with the protection expected from the cabin enclosure.
Aviation aluminum
20-25 mmLightweight aviation aluminum helps keep the structure practical to handle during installation.
Container plate
4-6 mmThe pressure-bearing plate provides a solid foundation for the chamber body.
Our pressure system
Dedicated gauges make the operating state easier to read and help the operator manage the pressure sequence.
Negative pressure gauge
-100 to 0 kPaIdentifies negative-pressure fault risk and alerts the operator to an abnormal state.
Positive pressure gauge
0 to 250 kPaMonitors the chamber working pressure and supports the controlled pressurization and depressurization sequence.
Our safety system
Manual and automatic relief paths provide clear response options for normal shutdown and abnormal pressure conditions.
Pressure relief valve
Manually operated at the end of use to release chamber pressure. The door is opened only after pressure returns to zero.
Safety valve
Opens automatically during an over-pressure fault to prevent the chamber pressure from rising too high.
Custom valve
Provides controlled micro-venting to keep the chamber pressure stable and balance the incoming air flow.
Our operating and communication system
The operating controls and communication points are arranged so that the user and operator can stay informed throughout everyday use.
Inner screen
The cabin display presents the key operating information inside the chamber.
Outer screen
The external panel keeps control information visible to the operator at the workstation.
Inner call
The cabin handset provides a direct voice channel for the occupant.
Outer call
The external handset lets the operator respond clearly without opening the chamber.
Our supporting equipment
Seating, lighting and entertainment options can be coordinated with the intended venue and user experience.
Aviation chair
Powered seating with a structured, premium cabin profile.
Space chair
A reclined seating option for a softer lounge-style interior.
Custom chair
A seating option that can be matched to the cabin finish and project needs.
Infrared lighting
A focused lighting option for a warmer interior atmosphere.
Starry ceiling
Decorative points of light add a distinctive ceiling finish.
Television
In-cabin entertainment for flexible everyday use.
