The Ingersoll Rand P185
          Tow Behind Compressor



There are probably tens of thousands of Ingersoll Rand P185 tow behind air compressors in use and for sale around the world. I have not been able to get any specific information on this venerable compressor from IR, except that it's a portable - being that it's a towed air compressor - and that it's supposed to provide 185 CFM of air flow when running optimally.

It was appears as though Ingersoll Rand is no longer selling portable contruction compressors, preferring to manufacture and sell construction equipment like jackhammers and what not as well as industrial air compressors. We understand that the portable construction compressor business was sold to Doosan Portable Power. If you have information confirming this, we would apreciate an update via the comment form below.
