I would suggest a stress test to determine current compressor capability, but the risk of a gasket failure might be too high. Do we have a backup to put in place quickly?
Just measured a similar compressor system here. Was at 23 cfm peak. but min psi.
Indeed, the compressor might well suffer some sort of mechanical failure. Repairs are prohibitively expensive, and often require a specialist to diagnose each sub-assembly. Complicated, apparently.
Yes, I believe it is more compicated than realized. Akin to changing the rings on an internal combustion motor while it is still running.....
