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.
What’s here on this Ingersoll Rand P185 Tow Behind Compressor page?
- status on the P185
- a 185 compressor manual and parts manual for no-charge download
- library of questions and responses
- section to ask your own question about this model and get help from other users
It appears as though Ingersoll Rand is no longer selling portable construction 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 appreciate an update via the comment form below.

Hi, I have a 94’ ingersoll-rand 185 pull behind unit. Worked fine until yesterday. For some reason when you turn it on it runs really high, same high (speed) when you push the service air button before it lowers its idle to normal. It runs high and nothing happens, you push the service air button and nothing happens not is there trapped pressure anywhere, as if the air compressor is not even connected to the engine. It just turns on and stays idling high. Need some help….
In need of a set of doors for a 175/185 tow behind compressor please let me know if anyone out there has any or knows where to possibly get some. Thank you.
I would like to swap the Yanmar engine in my Ingersoll Rand 185 air compressor with a John Deere engine. Is there conversion instructions out there?
Can’t find a parts diagram for the 185 we have. Need a radiator cap that has no numbers on it to help identify it. Runs the 3179 for the motor if that helps. Have the serial number but can’t find the model. Tried some of the local auto parts to match and there’s no old school people that know how to use a micrometer anymore
