28-Inch Soft Shell Hyperbaric Oxygen Chamber — 1.4 ATA Lie-Down

ATA stands for "atmospheres absolute," a measure of pressure. At 1.4 ATA, the chamber raises internal pressure to roughly 33% above normal sea level (about 5.8 PSI / 42 KPA). This is the mild-hyperbaric range most commonly used in home and wellness settings to support recovery and circulation.

Soft-shell chambers like the Oxyma are flexible, lighter, and designed for these mild pressures, using a welded fabric shell and an internal steel frame. Hard-shell chambers use rigid construction and can reach higher pressures, but they are heavier, more expensive, and typically aimed at clinical or higher-pressure protocols. For at-home recovery and wellness use, a 1.4 ATA soft-shell chamber is a popular, practical choice.

The Oxyma is designed to be simple enough to set up and operate alone. It runs on standard 110–120V power (220V is available on request) and includes an oil-free air compressor with 5-stage filtration that supplies high-volume air (72 LPM, 520 W). A dehumidifier and noise-reducing muffler are included, and internal and external gauges plus pressure-relief and emergency valves help you monitor and manage each session.

Oxygen is delivered under pressure through the included masks or nasal cannulas. An FDA-approved oxygen concentrator (10 LPM, 95% purity) is available as an optional add-on rather than standard equipment. Oxygen Health Systems also provides video setup training, Quick Tips guides, and 7-day customer support to help you get running, and 6 months of no-interest financing is available.

This is a single-occupant, lie-down (lying) chamber with a generous 28-inch diameter and an 89-inch length, so users can stretch out comfortably on the included mattress. It is well suited to athletes focused on recovery and performance, active individuals working through rehabilitation after intense training, and households that want a durable wellness tool at home.

Because it is a lie-down design rather than a seated or walk-in chamber, it is not configured for wheelchair entry, and it accommodates one person per session. If you specifically need a sitting or walk-in format, a different chamber style would be a better match.

That is a decision to make with a qualified physician. Mild hyperbaric oxygen therapy is generally used to support recovery, circulation, and overall wellness; it is not a substitute for medical care, and individual results vary.

Certain conditions can make hyperbaric sessions inadvisable, so anyone considering regular use should review their health history with a doctor first. As an authorized dealer, The Recovery Outlet can answer questions about the equipment itself, but we always recommend consulting a physician before beginning any hyperbaric protocol.
