# How does the pressure adjustment converter work?
Airvida’s hyperbaric chambers are equipped with a user-friendly **pressure adjustment converter** that makes it easy to control the chamber’s internal pressure with precision and safety.
This system allows users to **gradually increase pressure from 1.2 to 1.5 ATA (atmospheres absolute)** — ideal for maximizing comfort and minimizing pressure-related discomfort such as ear popping.

### 🧩 **For Soft-Shell Chambers (Home & Wellness Use)**
Airvida’s **soft-shell chambers** include a built-in **digital or manual pressure adjustment converter** that lets users set the desired pressure level with a single press or dial turn.
**Key Features:**
- 🔄 **Stepwise Pressure Control**: Adjust between **1.2, 1.3, 1.4, and 1.5 ATA**
- 👂 **Gentle Acclimation**: Minimizes ear pressure discomfort and supports smooth adaptation
- 🧠 **Intuitive Design**: No special training required — perfect for home users
- 🔒 **Built-In Safety**: Internal limiters prevent accidental over-pressurization
---
### 🛡 **For Hard-Shell Chambers (Clinical Use)**
Airvida’s **hard-shell chambers**, available by special order, can reach up to **2.0 ATA** for more advanced clinical applications. These systems typically use **manual or medical-grade pressure regulators** rather than the soft-shell converter.
**Key Notes:**
- 🛠 Designed for trained staff or medically supervised settings
- 🎯 Offers precise control for advanced treatment protocols
- ⚙ Uses **industrial-grade valves and gauges** for higher pressures
> ℹ️ *Note: The pressure adjustment converter described here is exclusive to Airvida’s soft-shell models. Hard-shell chambers use distinct mechanisms better suited for hospital-grade operation.*
