Solving DC Resonance

One of the goals of my recent shop remodel was to add a Dust Collection system. I chose the Grizzly 2HP system and put it in the uninsulated walkup attic above my shop. The floor of the attic was tongue and groove OSB sitting on 2X10 joists. The void in the joists was insulated with fiberglass batts, but I immediately noticed a humm resonating thru the OSB and joists. It wasn’t particularly loud, but I found it very annoying.

I improvised a frame that has worked very well. I had some leftover rigid packing foam that was 2” thick. I built a 2X6 frame that was a little over-sized for my DC base, plus a layer of foam around all 4 sides. I cut a piece of foam for the bottom as well. My DC is on wheels and to keep the wheels from tearing up the base foam, I cut a loose fitting OSB base that just floats on the foam.

No more resonance!! I can still hear the DC running, but it is very tolerable.

Very neat fix, having a low vloume humming all the time can and will become very annoying….

Great idea! I quited an overhead air compressor by mounting it on a platform then mounting the platform on three motor mounts. It kept everything quite but I believe your solution is more effective and cheaper to boot. Thanks for the idea, if I centralize my DC and move the motor upstairs I’ll be using your brain power.

Took another quick look, it’s even the same DC.
