About Atlas Copco
Atlas Copco of Nacka, Sweden, began doing business as AB Atlas back in the early 1870s and primarily served the railroad industry. In the 1890s, the company expanded to include central heating products and tool machinery. During that time, and into the early 1900s, Atlas started manufacturing air compressors, which led to the development of pneumatic hammers and other tools, as well as diesel engines. The company officially transitioned away from the locomotive industry in 1917 and took on the name Atlas Diesel that same year.

Through the post-World War I depression, the Great Depression, and World War II, Atlas went through several reconstructions, but it came out the other side with focused expansion in mind. While at the same time developing new rock drilling tools and drill bits to expand its pneumatic program, the company moved away from diesel manufacturing and officially became Atlas Copco in 1956.
From that point forward, the company went on to make several acquisitions, which allowed it to expand into new markets such as power generators, monitoring systems, light towers, vacuum solutions, and other construction and industrial products. Today, the Atlas Copco Group owns dozens of popular brands around the world, including ABAC in Italy, AGRE Kompressoren in Austria and Germany, Chicago Pneumatic in the United States, Pneumatech Medical Gas Solutions in the United Kingdom, and Guangzhou Linghein Compressor Co. in China.
