Thank you.
I took some suggestions and turned off the 110V compressor. Bled the pressure and found out that they stop knocking at around 45-50 psi.
The mufflers do nothing for the knock, just adjust the bleed pressure which controls the speed of the doors.
What is puzzling is that one door is fine, no knocking, and 2 are knocking at the higher pressure.
Next thing to try is the pressure regulator(s) on the 12v compressor as suggested above and see what I can accomplish.
The Aux compressors run 3 things - slide bladders, toilets and pocket doors.
The regulators installed before the slide bladders are set at 20 psi.
I know I have a check valve and pressure gauge on the 12V compressor manifold which receives air from the 110V compressor as well. I can see on the gauge that the pressure is about 40 psi when the 12v unit runs alone based on demand. As soon as the 110v compressor gets juice the pressure will go up to 70 psi.
Will have identify which lines go to toilets, which ones to pockets doors and maybe add regulators there...or....get 50 psi inline regulators that I install before the 4 way Ingersoll Rand (Norgren) valves that control each door that knocks...leave everything else be.....right ?
