This is my attempt at making my shop cyclone soundproof AND portable(ish). I wanted to soundproof the vac for the same reason as anyone who owns a cyclone does: the desire to clean up the shop without having the sound of a small jet taking off inside the room. I decided to make it portable because that way I could easily move it into a new workshop space and set it up quickly – no having assemble custom wall brackets and such. The whole contraption breaks down into three pieces in about 45 minutes: the filters, the hopper and the cyclone box (covered middle bit). I put it on casters too to help move it about the shop until I find to right place for it.

The impeller sits at the very top and was going to be covered by a soundproofed box with baffled ventilation ports. The cyclone portion was wrapped in Roxul® Safe and Sound, and then boxed in with OSB (because I could not afford plywood at the time on account of being a starving student). The hamper was boxed on three sides with an OSB – Roxul – OSB sandwich, with a plan to install a soundproofed door later. The filters at the side (two pleated canister jobs) were framed so that I could insulate them later.

I got a pretty decent reduction in decebel levels – about 20-30 db – but I know I can do better. The dull roar was reduced enough to be able to hold a conversation with someone, but not enough to be able to enjoy music. I have a new plan, but unfortunately, it is on hold until I get a new shop space. And so version 1.0 sits in a barn.

Very nice, thanks for sharing. Let us know how you like its performance and quite operation after using it a while.

I actually used it for about 2 months. The suction was pretty good, although when I redo this project I am going to listen to Bill Pentz’s advice, up the diameter of my ducts and make a cyclone following his design. I definitely can get it quieter, but at least it can no longer damage my hearing. Bill’s website, if you don’t have it already:

Great idea. What brand cyclone are you using? Do you like how it performs? I’m considering purchasing one. Thanks

What type of woodworking are you currently doing to need such a monster ? How many machines are you running at one time ?
I doubt that I’ll ever outgrow my 2HP JET DC with pre-seperator.It’s already on wheels and the noise level is minimum : ) Best wishes.

I inherited the cyclone, the hamper, and the impeller engine. I had helped my dad with the original set-up and purchasing of the dust collector for his old shop, but I forget the brands we settled on. I read quite a few books on dust control back in the day, but there is awesome info on Bill Pentz’s site (mentioned above) as well as No, I’m not making a sales pitch, but the info is awesome as a primer in dust collection.

To answer Dusty56, most of the size comes from soundproofing. Believe it or not, if I take it off the engine and the filter assembly at the top, the whole thing can roll through a 34” door frame – with the door still on. I usually run both my planer (15” Delta X5) and my 6” jointer at the same time, but the real test came from my tablesaw. I had a 20 foot run of solid ducting with three 90 degree turns and about 8 feet of flexible line. It took care of all of the dust.

Oh, the impeller is 1 1/2 hp. and when I move to my new place, I am totally redoing all of it to better follow Bill’s plans.
