Atlas Copco Compressors

Atlas Copco is a worldwide manufacturer of drillng, haulage, concrete equipment, compaction devices, air tools and motors, and yes, the Atlas Copco compressors.

Their air compressor lines include centrifugal compressors, high pressure compressors, reciprocating and rotary screw in lubed and non-lubricated design, and a broad range of tow-behind portable air compressors.

They have been around a while! The Atlas Copco we know today was founded in 1873. Their origins are, I believe, in Stockholm Sweden.
