ON2's Refuge One Air Centre provides and maintains a source of breathable air during an underground emergency.
ON2's Refuge One units may be used in a permanent refuge station or in a mobile refuge chamber, such as ON2's Tommyknocker. The unit purges CO2 by passing the chamber's air through CO2 scrubbers and replenishes O2 from high-pressure O2 cylinders at a metered rate based on the number of occupants. It is compact, sturdy, easy to operate, and can work independently despite the loss of the mine's electrical power or compressed air supply.
