Ingersoll Rand P185 Tow Behind Compressor
I have not been able to get any specific information on this venerable compressor from IR, except that it’s a portable compressor – being that it’s a towed air compressor – and that it’s designed to provide 185 CFM of airflow when running optimally.
It appears as though Ingersoll Rand is no longer selling portable construction compressors, preferring to manufacture and sell construction equipment like jackhammers and whatnot, as well as industrial air compressors.
We understand that the portable construction compressor business was sold to Doosan Portable Power. We would appreciate an update via the comment form below if you have information confirming this.

In the absence of troubleshooting information for the P185 family of Ingersoll Rand compressors, I am providing a forum here for users to post questions and respond if they can.
