This huge Norwalk water-cooled compressor was about 20 feet long, and was originally used in a commercial gas plant for compressing oxygen at 360 CFM! Tom tamed it down some by removing the original motor and replaced it with a puny 100 HP amp-sucking beast, but it still put out an amazing 160 CFM or more at 3000 psi. What a sound this baby made when it started up, churning at about 120 rpm, and creating a "Thump - Thump - Thump" that could be heard and felt by all nearby. Cold water from 60' down in the lake was pumped up to keep the monster cool. Check out the size of the two flywheels.
