In many remote communities, the thought of electricity is a distant reality. This leads to the notion of using oxygen therapy as being equally remote.

Oxygen is an essential medicine in the global fight against pneumonia.

FREO2 - Siphon is an electricity-free oxygen concentrator which is durable, affordable and has no ongoing costs. The system harnesses energy from a small amount of running water to  separate oxygen from the surrounding air.

FREO2 - Siphon's oxygen generator component is less susceptible to degradation due to humidity than contemporary oxygen generators. This is vital for reliable operation in the pacific region.

FREO2 - Siphon aims to give people greater control over their health by providing community health clinics with a vital tool in the timely treatment of pneumonia.
