Does YH Need Vibration Dampening?

I have continued to research the tips and best practices for using and getting the longest operating life out of a YH. Aside from the usual recommendations (avoid high heat, upgraded water pump, don't start under pressure, let it warm up, use Seco or Rarus, etc) I also noted several folks talking about vibration dampening as parts (screws, fittings, etc) are coming loose on their YH HPA compressors. Is this an issue with the YH(s) and have any of you experienced any problems with vibration breaking things on your YH?

If so what did you do to dampen your YH? I see some folks using the rubberized anti-fatigue shop mats under the YH and then more sophisticated mechanisms like this spring suspension vibration dampening frame:

So what say ye are the Yong Heng(s) slowly but surely committing hara-kiri and rattling themselves to death or is it a precaution? I appreciate any insight that you can share.

🤔interesting topic; I don't use pcp but I've ran many other compressor based things. I honestly think there shouldn't be much movement when running. But being as small as those are I would assume that gyroscopic forces play a much greater role in stability terms. That being said; most small compressors that I use have rubber feet or wheels on the frame; everything else is super snugged down(bolts,belts,etc). Now I am really interested in others responses 😵‍💫🤣🤪🤙

the 'no bounce' hammer head shakes like a cat pooping razor blades but the gauge stays still
you ever have your gauge shake so much , it forms bubbles? this cured my shakes, no more sudsy like bubbles. I have a second one attached to the frame on the other end of the compressor. The hammer absorbs a lot of the vibration

To my best knowledge and experience, the failures are from use of inferior oil and bad operating practices. Running too long, too hot, ect. Some older models were more at risk. Vibration dampening may help some, but I just don't see it. It's not like the crank case or cylinder is failing. Typically the seals fail. Which is normal after a while.

FINALLY! Someone that really gets it! 118 hours on mine so far, purchased in 2021, still running strong.

Mine has less hours than that, and has failed multiple times. Inferior oil and bad operating practices. My crank shaft is bent and epoxied together. (I had to reduce piston height, as it was smacking the cylinder head, lol) I'm on rod and piston #3 and havnt had to repair it in 2 years. Still use it regularly. But oil I use is far better, keep it much cooler, rear fan is upgraded, and I don't run it more than 10min, don't start or stop it under load.

So, I've broken pistons, rods, broken crank bolts, and the crank is actually technically broken, and I still use it, lol.

I only fill a 9 litre tank with it. But I fill all my guns with the tank.

Going on 3 years with mine (YongHeng) & never a problem YET. From day 1 I resolved to treat it kindly, use good oil, keep it cool (fans front & back/frozen water in milk containers in the water reservoir), never run more than 15 minutes without a cool off break and ONLY top off tanks to 4200-4250psi MAX. It has served me well. I have spare parts & a backup YH for the inevitable "day of infamy" but that day hasn't arrived. When it does, I'm prepared.

MY long story is I bought a 'YH' in 2020, it turned out to be a fake or perhaps a first gen with only 2 second stage washers. I was counseled by the great people over at GTA and bought a real YH with the auto off function.

Why?

The counterfeiters dont do an auto off machine, they are all real YH compressors.

I bought Nuvair 455 breathing compressor oil and run it from 3k to 4k, never any higher than that, ever. I use cold water but never ice, the temperature differential is not good for seals or metal, my ΔT is about 100°F and that is as high as I want to go.

I have a full piston and seal kit rebuild on hand for when I fry the second stage. It's not a matter of 'if' but 'when'.

Agreed on using good oil!

I am wanting the vibration dampening solely to make it more quiet.
