I need help with my Ingersoll Rand tow behind/portable air compressor.

Ingersoll Rand no longer manufacturers or sells tow behind/portable air compressor. Doosan Portable Power purchased the portable air compressor division in 2007.

Unfortunately, Ingersoll Rand no longer offers customer support for these units.  You can reach Doosan Portable Power for customer service through the below channels:
