Design Specifications

The system combines the components of an oxygen concentrator, an oxygen compressor/filling station, solar panels, and pulse oximetry. It also relies on refillable oxygen cylinders. The oxygen concentrator and compressor have a sealed enclosure. A filtration system is used to protect from dust and a de-humidification system regulates the internal humidity levels.  Sealed Enclosure of the SPOCC provides a sound operating environment for the oxygen concentrator and compressor. The O2 Cube fills Size "C/M9" oxygen cylinders at a rate of 110 min/cylinder. It is designed to supply up to 15 cylinders per week.
