Sanborn Air Compressors


The history of Sanborn air compressors is convoluted. They were manufactured originally by the Sanborn Manufacturing Company in Springfield, Minnesota, and the brand was the Black Max air compressor. Sanborn Manufacturing then was acquired by Coleman Powermate, Inc.

Subsequently, the Black Max air compressor line was discontinued as the original Sanborn brand.

The Black Max then became the Powermate brand of air compressor.


Sanborn Air Compressors - Black Max Sanborn air compressor

MAT Industries, LLC then purchased the Coleman Powermate plant in 2008. According to the www.nujournal.com, "MAT Holdings, Inc., is a $600 million privately held company supplying hardware, air compressors and automotive parts and accessories in North America and worldwide. MAT Holdings, Inc. is currently headquartered in Lincolnshire, Ill."

Tracking down information on the Sanborn compressor is, as I say, quite convoluted. For the present, if you are seeking information about support for your Sanborn, as well as reading the questions and answers on this site, you could try contacting them at: www.powermate.com
