Air-purification system

A massive air-purification system is present in the Transport to Temple Grounds room in the Torvus Bog, behind the actual Elevator. According to its scan, it is still running. However, lack of maintenance has left it damaged, and the Scan Visor estimates that it will shut down if not tended to within three cycles of the events of Metroid Prime 2: Echoes.

Scan
"Structural analysis complete. This is part of an air-purification system. This unit is still active, if only at a basic level. Scans indicate a general lack of maintenance: if this unit is not serviced within the next three cycles, it will cease to function."
