Soft hyperbaric chambers are becoming more popular in wellness centers, sports clinics, and even home use. But many people don’t fully understand what makes one oxygen chamber different from another. In this article, we’ll break down the basics of soft hyperbaric oxygen chambers, explain the difference between 1.3 and 1.5 ATA.
What Is ATA in Hyperbaric Chambers?
ATA stands for Atmospheres Absolute. It measures the pressure inside the chamber compared to normal air pressure at sea level (which is 1.0 ATA). A 1.3 ATA chamber increases pressure by 30%. A 1.5 ATA chamber increases pressure by 50%.
Why does pressure matter? Because pressure helps your body absorb more oxygen. Under increased pressure, oxygen dissolves more effectively into your blood plasma. This extra oxygen can support healing, reduce inflammation, and improve cell repair.
Many soft hyperbaric chambers offer 1.3 ATA, but newer models now support 1.5 ATA safely. That small difference—just 0.2—can actually increase oxygen intake by 20-40%, depending on conditions. This makes 1.5 ATA ideal for deeper tissue recovery, faster post-injury healing, and more intensive wellness treatments.
1.3 ATA vs 1.5 ATA Soft Hbot Chamber
| Feature | 1.3 ATA | 1.5 ATA |
|---|---|---|
| Pressure Increase | 30% | 50% |
| Oxygen Absorption | Moderate | High |
| Session Comfort | Very comfortable | Slightly more intense |
| Suitable For | Light wellness, general recovery | Sports rehab, deeper healing, medical-grade therapy |
| Equipment Cost | Lower | Higher |
How Safety Is Built into Soft Hyperbaric Chambers
Safety is the top concern when using pressurized oxygen devices. Good soft hyperbaric chambers are designed with multiple layers of protection.
1. Dual Zipper System
A dual zipper design helps maintain an airtight seal. The outer zipper provides structure, and the inner zipper holds pressure. Together, they create a double lock system to prevent leaks.
2. Pressure Relief Valves
Every high-quality chamber has automatic pressure release valves. These valves protect the user by slowly venting air if pressure rises too high or in case of emergency shutdown.
3. High-Tensile Materials
Most soft chambers use TPU (thermoplastic polyurethane) or TPU + medical-grade PVC. These materials are strong, flexible, and resistant to wear.
OXY CHENY soft chambers, for example, include all of the above systems and are built in a certified factory with over 10 years of export experience.
