These compressors ran 24 hours a day, making compressed air, which was piped to the mines on the Butte Hill to operate drills underground and to power hoists (originally run by steam).
Several other mines had similar compressor plants – all are gone today.
Lloyd Harkins saved these wheels and many other Butte historic artifacts from being scrapped when underground mining shut down.
