Northern Indiana | The system used a multi piston compressor with progressive stages. Basically cylinder one fed to two, three and then four. The last compressor we had was four stage.
Moisture needed to be drained regularly when operating, the newer ones do this automatically. Then the air goes thru an elaborate filter and drier setup that also has Co detection that would shut the whole system down if levels were too high. From there the air went off to a series of tanks called a cascade system.
The cascade system would be a group of tanks set up in series. Tank one, two three etc would be depleted in such a way to maximize capacity. Because the compressor was high pressure and not high volume it would take a long time to fill these tanks. Depending on the system capacity several hours.
When filling bottles they would get warm. The bottle being filled is placed in a tub of water or an explosion proof cabinet to protect the operator in the event of a catastrophic failure. Many times you would overfill the bottle somewhat because as the air cooled it would become more dense and the bottle pressure would drop.
There’s the basics of how it works. | |

Air compressor?
