REFUGE ONE AIR CENTRE - Double Bed

ON2‘s Refuge One Air Centre provides and maintains a source of Breathable Air during an underground emergency. The Air Centres may be used in a permanent Refuge Station or in a Mobile Refuge Chamber such as the ON2 TommyKnocker. The unit removes excess CO2 by passing the chamber’s air through sodalime 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 transport. The Refuge One can also work independently, despite the loss of the mine’s electrical power or compressed air supply. The double bed scrubber provides twice the CO2 absorption capacity using 160 SCFM of air flow. Please refer to “The Performance of Refuge Air Centre” information summary.
