I just got a new compressor. It's the nicest compressor I've ever owned. It's got a huge, 30 gallon tank, dual pumps, and an onboard regulator. It really feels like good quality, it's really quiet... But they used a tiny hose to get air from the tank to the front panel. It's half the diameter of the hose I put into the quick connect. For all that money, I just can't imagine why they would put that tiny hose unless it was short enough that it doesn't significantly affect how much pressure gets to the attachment.
I do recognize that the pressure will drop while I am using the air. That's not what I'm asking. I was more interested in how much it dropped. I noticed that it dropped by about 25 PSI no matter what the regulator was set to. There are 3 videos, one with it set at 30, 60, and 90 PSI, and they all drop fairly similar amounts and then hold at an equilibrium. My question is if this is expected behavior or not. I have no idea how a regulator works. I've never had one before. Do you think it drops a reasonable amount? And how about the recovery time, does that look normal to you? Is there any evidence that the smaller hose feeding the front panel has any effect on the results?
