HUBBLE BREATHABLE AIR UNIT is designed to supply breathable air for trapped miners during a mine emergency.
The unit contains an
air compressor , air filter/purifier system , and a diesel powered
generator for back up emergency power. The air compressor unit supplies compressed air to the purifier, which diverts compressed
air through the filtering system and into the outlet discharge valve for delivery. The unit is stored in a
metal enclosure located on the surface of a deep mine operation. Breathable air is supplied through a pipe line that extends from the
unit on the surface to a breathable air station underground.
