The main difference between a soft-shell and hard-shell hyperbaric chamber is the enclosure: soft-shell models use a flexible chamber; hard-shell models use a rigid body. That affects purchase price, access, delivery and how much space the complete setup needs.
Neither construction is automatically the better buy. Start with the documented intended use, the layout you need and the installation constraints. Then compare the exact models and included equipment.
Soft-shell vs hard-shell: the practical differences
| Consideration | Soft-shell | Hard-shell |
|---|---|---|
| Enclosure | Flexible chamber with model-specific frame arrangement | Rigid enclosure with model-specific door or entrance |
| Current OxyAir prices | $6,499–$9,499 | $30,599–$84,999 |
| Supplier-listed maximum working pressure | 1.5 ATA for the listed OxyAir models | 2.0 ATA for the listed OxyAir models |
| Layouts available | Lying, sitting, convertible and two-person options | Lying, single-seat and two-seat options |
| Moving and delivery | Flexible construction may simplify relocation; frames and support modules still need planning | Packed dimensions, weight, access route and unloading are especially important |
| Room footprint | Chamber plus entry space, frame, external equipment and service access | Chamber plus door movement, external equipment and service access |

When is a soft-shell model worth considering?
A soft-shell model is a useful starting point when a lower equipment budget or the possibility of moving the setup matters. The flexible enclosure does not make the entire system small: compressors, cooling equipment, oxygen supply equipment and the frame still require space.
Compare the OLV-RT01 lying chamber, OLV-RZ01 sitting chamber and OLV-RZT01 lying-and-sitting chamber by entrance arrangement and usable layout. The OLV-RD02 is the two-person soft-shell option in this range.
“Portable” should not be read as “ready to move during use” or “suitable for every room.” Follow the model’s setup, handling and operating instructions.
When is a hard-shell model worth comparing?
A hard-shell chamber has a rigid structure and a more substantial delivery and access requirement. It is worth comparing when that construction and the available layout suit the project, and the delivery route can accommodate the packed unit.
The OLV-YTD04 and new-generation OLV-YTD03 provide lying layouts. The OLV-YZD01 is a single-seat model, while the OLV-YZM02 has a two-person seated layout.
For a facility, capacity is only one part of the decision. Also check the manufacturer’s intended use, staffing and training requirements, maintenance arrangements and the installation’s applicable requirements. A hard shell or a higher listed pressure does not establish medical clearance or a treatment advantage.
Sitting or lying: choose the layout separately
Shell construction and body position are different choices. Both categories in this range include seated and lying arrangements, so you do not need to choose a rigid chamber simply to obtain a seat.
- Lying: compare entry, internal length and width, viewing windows and the supplied support surface.
- Sitting: compare entrance width, seat arrangement, headroom and access to controls.
- Two-person: check the actual internal seating or lying layout, rather than relying only on the capacity label.
Photos help explain the shape and access, but use the current technical drawings and operating documentation for dimensions and requirements.
Compare the full system—not just the shell
Before comparing quotes, put the chamber, compressor, oxygen supply, cooling equipment and frame arrangements side by side. OxyAir’s current soft-shell quotation includes an air cooler and one metal frame, selected as internal or external. Other equipment details vary by model.
Ask how controls are accessed, what training is provided and how the chamber is maintained. Warranty comparisons should distinguish parts from shipping, labor and on-site travel. These details are more useful than an unsupported claim that one shell type is always more durable or easier to operate.
Measure the route in, then the room
- Obtain the exact packed dimensions, weight and unloading requirements.
- Measure the narrowest doors, hallways, turns and any stairs on the access route.
- Draw the installed chamber, entrance or door movement and external equipment on the room plan.
- Add the manufacturer’s servicing, electrical and ventilation requirements.
- Confirm who is responsible for unloading, positioning and commissioning.
A soft-shell chamber can still have a large installed footprint. A hard-shell chamber that fits inside the room may not fit through the route to it.
Which should you choose?
Shortlist a soft-shell model if its documented configuration meets your requirements and the lower equipment price or flexible construction is useful. Shortlist a hard-shell model if you need that model’s rigid layout and can accommodate its complete installation. If neither meets the intended-use or site requirements, neither is the right purchase.
For budget planning, use our hyperbaric chamber cost guide. It lists all eight OxyAir prices and separates equipment cost from delivery, room preparation and support.
Does higher pressure mean better results?
No buying decision should be based on that assumption. This guide compares equipment, not clinical outcomes or treatment protocols. The FDA’s safety guidance stresses manufacturer instructions, training and fire prevention for hyperbaric oxygen therapy devices. Suitability and applicable requirements need to be established for the exact device and use.
