have 9 year old wash,, 2 iba, 4 self service. currently have 2 mid - low grade quality air compressors, 3hp, 60gal., both are starting to give me probs, i.e. bearing knocking, warped head, have already replaced both motors, etc. i am considering purchasing one, 80-100 gal, 5hp. 3 phase industrial quality compressor, i also really need the equip. room space. i will plumb it so that i could via quick connect bypass entire system and bring in my 30 gallon on wheels compressor in case of failure. please give me opinions as to pro / cons of this approach. thanks
