FAQs

What does “ASME code compliant” mean for this chamber?

It means the 4 mm 304 stainless-steel pressure vessel is engineered and documented to American Society of Mechanical Engineers (ASME) pressure-vessel standards — a recognized benchmark for the hull, welds, and pressure system.

How many people does it hold?

The 64-inch walk-in cabin seats two to three users with customizable seating, so an attendant can run a group session at once.

Do I need special venting?

No. The dual redundant compressor system maintains a safe 23% ambient oxygen level in the room while delivering up to 95% oxygen by mask, so no special venting is required. Follow local codes and the manufacturer's installation guidance.

Is hyperbaric therapy right for me?

Hyperbaric oxygen therapy is generally used to support recovery, circulation, and overall wellness, but individual results vary and it is not a substitute for medical care. Consult a qualified physician before beginning any hyperbaric protocol.
