The largest chamber in our hyperbaric wellness product line, the Fortius420® allows the user or operator to choose between the most common pre-set pressure options: 1.3 ATA, 1.5 ATA, 1.75 ATA and 2.0 ATA in the EU and UK (with optional upgrades to 2.2 ATA and 3.0 ATA medical versions where available and permittable – restrictions apply). The chamber has been designed to be portable, fit into most facilities, offices and homes, despite its sizable 107 cm (42″) internal diameter. The chamber has sufficient space to comfortably fit two adults, comes with external and internal mirrored controls to provide effective functionality and safety allowing for self-operation without outside help. The chamber is perfect for both clinical and private use. Ingeniously designed with top-of-the-class technology the chamber can be shipped to the client and installed on average in less than 10 business days.
