36" Hard Shell Hyperbaric Oxygen Chamber — 1.5 ATA Single-Person Lie-Down

ATA stands for "atmospheres absolute," a measure of the air pressure inside the chamber. At 1.5 ATA the chamber is pressurized to about 1.5 times normal sea-level pressure (roughly 52 KPa of added pressure), and this model also lets you step up to 1.6 ATA (60 KPa) when you want a slightly higher setting.

This is a hard-shell chamber, meaning it's a rigid pressure vessel built from 304-grade stainless steel rather than flexible fabric. Hard-shell construction is engineered for greater durability than soft-sided models and supports these higher selectable pressures within a sealed, gauge-monitored system.

The chamber uses an all-in-one onboard system, so there's no separate oxygen tank to manage. A built-in 10 L/min concentrator generates oxygen at up to 95% purity and delivers it through the included headsets, nasal cannulas, and facemasks, while an integrated air compressor and dehumidifier handle pressurization and humidity.

An automatic air-pressure system manages the pressure-sealed polycarbonate door, and a silent pressure-relief safety valve keeps operating noise to roughly 52 dB. Because the unit is a professional-grade installation, our team will walk you through power, placement, and operating requirements before delivery — reach out and we'll confirm the details for your space.

This is a single-person, horizontal lie-down chamber with a 36-inch interior, a padded mattress, and a pillow — designed for one user to relax fully during a session rather than sit upright. It's a good fit for athletes and active individuals focused on recovery, as well as wellness centers, physical therapy clinics, and home users who want clinical-grade hardware.

Because it's a lie-down hard chamber accessed through an easy-slide door, it is not a walk-in or wheelchair-ready unit and is not a sitting or vertical tubular chamber. If you need a specific access configuration, contact us and we'll help you compare options across the catalog.

Hyperbaric oxygen therapy is generally used to support recovery, circulation, and overall wellness. Individual results vary, and it is not a substitute for medical care or a treatment for any specific disease.

Because everyone's health situation is different, you should always consult a qualified physician before beginning any hyperbaric protocol, especially if you have an existing medical condition. The Recovery Outlet is an authorized dealer and is happy to answer questions about the equipment itself — for medical guidance, please speak with your doctor.
