The ACX system is ideal for customers who require extended periods of high altitude exposure to achieve their desired result. It offers an extra-large altitude chamber that is better suited for this purpose than the legacy AC system and a fixed altitude setting of 10,000’ for simulated elevation.

Who is the ACX for? 

Specifically, the ACX system is recommended for customers interested in brainO2 training, condition resolution, and athletic performance, as it provides a superior experience. The larger chamber allows for longer and more intense hypoxic sessions, which can be highly beneficial for enhancing oxygen absorption in the body and brain. This makes it particularly useful for individuals dealing with health challenges who require extended periods of hypoxic training. In addition, the ACX system is suitable for anyone seeking to optimize their health and wellness, including athletes seeking to improve their performance through altitude training. It features user-friendly controls and an advanced oxygen delivery system, making it a comfortable and effective tool for high altitude training.
