Hello folks,

Need some help. Time to turn my attention to some of the air systems inside.

2 of my 3 air pocket doors open and close with a "bang" at the end of the travel.
The door leading to the bedroom does not make any noise. Operates smoothly.....but the bedroom to rear bath bangs, and the rear closet door bangs as well.
Can not figure out what is causing that cylinder or mechanism to make that noise. It is like a metal clank on a striker plate. Both when closing and then on opening.
I watched and felt the air solenoids when the door is operated. They allow the air to go through fine and at the end of the travel the cylinder bangs...the very end. No bang in or near the solenoid...all up by the cylinder inside the upper door....of course.

I am running about 25 psi on both regulators that feed the slide seals and toilets.
Are the doors fed by a different regulator somewhere ?
I am hooked to power, inside a building and the 110V compressor is active maintaining about 90 psi in the Aux air system.
The compressor starts when the air gets down to about 75 psi, runs for 1.5 min and shuts off when the air gets to 90 psi. It cycles about every 3 hrs, so I know there are some leaks I have to attack.

Any ideas ? Anybody has had this happen to theirs ?
Thanks for any suggestions

I have a similar problem. The air pressure was set at 45psi. I adjusted the air pressure and dropped it down to about 35. This seemed to help the door noise. HOWEVER my air system is also connected to the toilet. When I lowered the air pressure the toilet did not operate correctly. I read the manual on the toilet and it says to operate at 60 psi. Unless I separate the air door from the toilet, I am not sure I can correct my door noise.
