Most combustions use the oxygen present at 21% in the air. The gas supply replaces part of the atmosphere.
The oxygen level is lowered by dilution. A rate reduced to 15% oxygen in about ten minutes to extinguish a fire start up. (Some special situations may require a lower rate.)
This technology is particularly efficient and economical, but this gas is harmful to the environment and potentially dangerous in high concentrations.
This concept meets NFPA 12 standards.
