I have and Ingersoll Rand 185 tow behind compressor. I haven't had any real problems with it but when I am using my abrasive pickup (which uses 100cfm) it cannot maintain 100 psi. It drops down to 80psi and takes forever to vacume up the media. It doesn't matter if It is 50ft of hose or 200ft the pressure won't stay above 80. Anyone have a problem like this before?
