Ok, so as i'm fixing more and more things on our gauntlet, we just started noticing we are getting big pressure drops on our gauntlet. We like keeping our presses at 110psi, and the gauntlet keeps jumping between 80 and 110. Wether it's running or sitting, it's fluctuating.
There are two air leaks on the press, but they are minor, and each night i've been eliminating them.
We just had a ton of work done on our compressors, in preparation for new equipment, and for the installation of an air loop in the shop, so i don't think that's the issue.
I replaced the filter/regulator in July 13, with a brand new one from M&R, but i'm starting to wonder if that is the issue? Our increase/decrease knob seems to max out/get stuck at 80psi, but will jump at different points during the day to 110, then back down.
Any ideas?

Ok normally psi is not as big as cfm, but that is a good size drop. What size compressor you running with what presses. My 97 gauntlet take 28-32 cfm as 100psi aprox. I using 1" line to help with some volume. How about chiller? or water in line.
My thoughts.

i'm running a Ingersol Rand 30cfm vertical tank, into two storage tanks, then into a 50cfm chiller, so there shouldn't be any water in the line. The compressor has def. handled this press (97 gauntlet s), plus a second bigger auto, and a smaller air flatstock press, all running at max cap. before.
I just did a small 1 color print run of 50 tees, and noticed when the press is sitting still it goes up to 110psi, then drops to 80psi. this is according to the filter/regulator gauge

Pretty sure you can run that regulator on 120. Surely Rich will jump in here any minute.

it says on the regulator max psi is 150, but we never ran it that high.
what's making me scratch my head, is why it gets maxed out, but won't load higher than 110, especially since all of my compressor tanks are set between 130 and 150

Usually a gauge dropping like that is a lack of volume or cfm. The pressure will drop as the demand increases, you should notice it drop during high demand functions like lift and or index.
Could be a restricted air supply (bad hose, pipe sealant in the line or regulator, etc) or the regulator could be bad or a bad gauge. If you are not noticing a performance problem I would look at the gauge.
IMO the pressure should be kept between 90-100 psi, there should be no need to go higher. Higher pressures you are just working the pneumatic components harder then necessary.

if you were just working on the line you probably have contaminates from the pipe in the filter/ regulator. Take the filter out and try running with it out. Test only! Don't run this way. If pressure stay good replace filter.

which part is the filter? it's the unit on the left correct? as the right side is the oiler?
