I'm thinking about upgrading from a single stage to a two stage unit. Ive been looking at the IR's 5hp and Quincy 5hp two stage 60 gallon units. I currently have a 5hp IR 80 gallon single stage and it seems to do fine, but the operating range is 90-135psi. The two stage units are 140-175psi. I believe this would help me with my epoxy issues as well. At first I thought about selling the IR, but to be honest I think I would be better off still using it for everything but paint. It runs the da's and sandblasters great, plus the money I would get out of it just wouldn't be worth it. I would be able to do all my prep work and still have a fresh unit that is not boiling over with heat in the summer.
Anyway with that said I have been looking at the specs on my filters for max psi ratings. At my paint station I run an RTI 204mi and a Devilbiss ct30 dessicant system. The max pressure on the rti stuff is 150psi. So I could just plumb in a regulator before the paint station and set it at 140 and be ok.
My compressor is located in a basement of a building next to the garage. I have about 40ft of air line before it gets to the work stations. I also run a Motor Guard m60 at the compressor. The max psi for it is 125 psi. With my current setup I'm already 10psi over when the compressor is fully charged. The tech support at Motor Guard told me that that particular filter was not doing anything for me there. I mainly put it there for oil vapors, but it does catch a lot of water. I also have a m60 and regulator at what I call my general air tool station. I very rarely get any water in that m60, but I do get some in the drop before it turns to the m60.
So if I do add the two stage unit to my system I will have to re-arrange my setup at the compressors and the two stage would have to enter on the other side of the m60. I would also incorporate a few ball valves so that only one compressor is feeding the system. As for the electric I will just plug up which ever compressor is going to be used. They both have the same power requirements. I thought about hooking them together and such but I'm a little worried I wouldn't have the electric capacity to run both at the same time. Running would probably be ok, startup would be another story, plus the pressure setting are so far apart the single stage would never come on. I also thought about buying a new pump, but what I would pay for a pump I can just about buy the extra compressor, not including the pressure relief valves.
I think this would make a really nice setup, I'm just worried about losing the m60 at the new compressor. Maybe I've gone crazy. What do you guys think? Thanks, Russ
