I plan to hang a 2hp cyclone off of a wall in my garage. I built the wall - it's stick built with solid headers and footers, and anchored to the cement floor with power actuated nails and construsction adhesives and to the ceiling joists with lag bolts. The wall has insulation and a pegboard face on the shop side and drywall on the garage side. I was thinking I would use lags to attach some 2x12 left over from my Roubo build, and attach the cyclone brackets to that.
As I think about the install, and read about sources of noise for wall hung cyclones, it seems that there is more noise generated if the unit is wall hung.
Has anyone used some kind of a dampener - or rubber barrier - between the wall and the cyclone? In my proposed install, that dampener would go between the 2x12 and the pegboard.
At the moment the DC looks like it will be installed inside my shop, so noise reduction is a real issue. I also want to limit transmission into the house through the adjacent cinderblock in the garage.
TIA

It not a wall hung cyclone, but it is a hung DC.
I lag bolted my DC to the ceiling and found that it was "LOUD" -- As you might have guessed it would be, turning the house into a giant DC powered drum.
So I got some window weather stripping ( cheap sticky back foam rubber, doubled up 3/4") -- the dark between the to light 'boards' -- and hung my DC for some Plywood with over sized holes for the lags, that sits on the weather stripping, that sits on a 5/4 chuck of hard wood that hangs on long lags into my cealing joists (one side shown).
Night and day difference. The sound level drop to a level that was expectable in the shop, and reduce the whole house noise to pre hung levels.
I even when so far as to add a few back-up lag bolts (with big washers) through over sized holes that are only there in case something else fails. I am hoping that if something comes loose the weight of the DC will fall to these back-up bolts and the noise increase to pre-isolated levels and I will notice ASAP and fix the problem.
Anyway, not really what you asked about, but maybe it can give you a few ideas.

I too have read the feedback provided by others, and, IMO, this is where I think a free standing stand with sound dampening (e.g. rubber) feet would be ideal.

I think that most of the hype is hoooey . I have no vibration damping on my unit; it is hung on a piece of 3/4" ply against drywall on the opposite side of my office wall. I am happily typing away in here while it is running without vibration on the other side of said wall. I do hear it operating however, which means I really should go back to work

My experience as well. Wall hung and no problems or noise here.
I suppose if something were out of balance it would reverberate but that is not the case with mine.

Mine is mounted to the wall and it's loud but I don't think it would be much worse if it was stand mounted. If i was really concerned with noise I would enclose it before trying some kind of dampening material at the mounting points.

If your cyclone is vibrating you have bigger problems because the fan is balanced. No amount of rubber
isolation dampers is going to reduce the overall noise. If you want to reduce the cyclone's noise output,
start planing some oak.

Sounds like you're doing exactly what I did in my last shop with a previous Oneida DC. There was no problem with vibration on my makeshift wall with the DC hung on it.

Are those glass jars hung on your ceiling? Never hit one with anything?

Made mine from Wood Mag plans a few years ago. Just hung mine on the wall with a french cleat. Never have had any problems.
