ATA Pressure Explained: 1.3, 1.5 and 2.0 ATA

ATA tells you how much pressure a chamber is designed to hold. Compare it alongside chamber construction, oxygen delivery, operating environment and user capacity; the highest number is not automatically the best fit.

What Does ATA Mean?

ATA stands for atmosphere absolute. One ATA is normal sea-level pressure; 1.5 ATA is 50% above that reference, and 2.0 ATA is twice sea-level pressure. Higher pressure can increase the amount of oxygen dissolved in plasma, but it also changes chamber construction, equalization and operating requirements.

1.3 ATA — the Gentle Entry Point

A 1.3 ATA portable soft chamber provides a gentle pressure change and is typically easier for first-time users to equalize. It suits buyers prioritizing home installation, comfort and a simple daily wellness routine. The COSL13 is a representative 1.3 ATA lying system.

1.5 ATA — the Most Popular Home Choice

A 1.5 ATA soft chamber gives home and wellness buyers more pressure while retaining portable construction and straightforward operation. Choose between lying and sitting by posture, room shape and entry preference: the COSL15 is a lying model, while the COSE15 provides a spacious sitting interior.

2.0 ATA — Clinic-Grade Performance

2.0 ATA is the top of CONSIDER's current chamber range. It is available in fixed hard-shell clinic systems such as the COHT20 and in reinforced professional soft models such as the COSL20 and COST20. Buyers should confirm room access, supervision, intended use and operating workflow before selecting this tier.

Which Pressure Should You Choose?

• Choose 1.3 ATA when gentle pressure, home installation and easy equalization are the priorities.
• Choose 1.5 ATA when you want a mainstream home or wellness configuration with lying and sitting options.
• Consider 2.0 ATA when the operating environment, supervision and chamber construction support a professional workflow.
