The oldest P175 I've seen on line was built mid-'70s, making the model number at least 40 years old.
Have you an older IR P175? Feel free to use the forum form below to send in a few photos and give us some history on your P175 air compressor, if you would like to brag about it a bit. Or complain, for that matter!
Lots of them are in use. Not a lot of information about fixing or maintaining them... at least as far as I'm able to find. So, this forum page is to let users of the P175 compressor to post questions about their compressor (please upload photos showing the problem area).
If you have experience with the P175 and see a question you can help with, please comment. That helps the one person, and anyone else that finds the page that is experiencing the same issue with an IR P175 portable compressor.
All IR P175 compressor users, and me, say thanks a bunch.
