Paragon uses analytical tools and human space flight experience to design & deliver Atmospheric Ventilations systems that are customized for the vehicle internal volume and layout. The system is designed to ensure sufficient mixing of gases, avoid stagnation, and accommodate temperature, humidity, and CO2 requirements. In addition to the Atmospheric Revitalization System (ARS), Paragon is currently designing the Atmospheric Ventilation System (AVS) for the NASA Gateway HALO Program.
