    The GAG unit emits carbon dioxide, nitrogen and water vapour. [4] The gases lower the oxygen levels, suppressing fires, and forcing methane out of the mine. [5] A unit is capable of pumping a volume of 25 m 3 /s, creating levels of less than 1% oxygen. [3] When fully assembled, the unit is 12 metres long and weighs 2.5 tonnes. [4]
