OxyHealth's hard-shell clinical chamber - a single-occupant monoplace rated up to 3.0 ATA, well beyond the soft-shell 1.3 ATA tier.
The Fortius 420 is the OxyHealth tier where the chamber crosses from soft-shell mild HBOT into hard-shell clinical equipment. It is a rigid-walled monoplace chamber: a single occupant, 42-inch interior diameter, rated up to 3.0 ATA (about 29 psi) rather than the 1.3 ATA ceiling of the soft Vitaeris and Solace models. That higher pressure is what separates clinical-grade HBOT from the mild-HBOT wellness tier.
For buyers who specifically need true clinical pressures, this is the OxyHealth pick - the hard shell holds the higher ATA the soft chambers cannot, which opens the recognized higher-pressure protocols. It is meaningfully more involved to own than a soft chamber and is built around one person per session.
The install footprint becomes a real consideration: 12×6 ft minimum, 9-foot ceiling clearance preferred. Most buyers dedicate a wellness room or basement section to this tier.
Buyers who specifically need hard-shell clinical pressures above the soft 1.3 ATA tier in a single-occupant chamber. Family offices and private suites building a clinical-grade hyperbaric setup.
You only need mild 1.3 ATA HBOT (the soft-shell Vitaeris or Solace are sufficient and far simpler), or you can't accommodate the 12×6 ft + ceiling footprint.

OxyHealth Fortius 420 - buyer FAQ
Is the Fortius 420 a single-occupant chamber?
Yes. The Fortius 420 is a single-occupant monoplace - one person per session in a 42-inch interior. It is not a multi-place chamber and is not designed to seat two adults at once. What sets it apart from the Vitaeris and Solace is not occupancy but construction and pressure: it is a hard-shell clinical chamber rated up to 3.0 ATA, while those soft-shell models cap at 1.3 ATA.
Fortius 420 vs commercial-grade clinical chambers?
The Fortius is a hard-shell clinical monoplace rated up to 3.0 ATA (29 psi), so it already sits in clinical-pressure territory rather than the soft 1.3 ATA mild-HBOT tier. Larger multi-place hospital chambers (multiple occupants under pressure) run $150-500K and are specced for medical facilities. The Fortius is the right tier for a buyer who needs true clinical pressure in a single-occupant chamber without a room-scale multi-place install.
What does the typical Fortius 420 install look like?
12 x 6 ft floor footprint, 9-foot ceiling clearance preferred (8 ft minimum), 120V standard outlet, and ventilation for the compressor. Most buyers dedicate a wellness room, finished basement, or converted home office. White-glove install service is typically $2-4K additional and includes assembly, pressure testing, and owner training.
