Shop Vac Silencer Cart

I built this cart after being constantly annoyed by how loud my shop vac was. I saw this in a video by one of the woodworking magazines. Cabinet is 3/4” mdf lined with a sound insulating panel (4×8) from Rona. It’s a green wood/paper product. I cut the panel to fit all of the inside surfaces and wrapped it with an old black bedsheet. There is a maze built into the bottom for the exhaust air to flow out of. Air goes into the 2 holes in the corner of the main compartment and flows to the back. 2 holes connect it to the middle chamber and it flows to the front and then to the 3rd chamber to the back and out the exterior holes. Vac is very quiet now and with the addition of the dust deputy, I only have to check it once a year (to clean the Gore Clearstream hepa filter).

Top holds my drill press, sander and grinder.

I did that on an old really noisy shop vac back before they made quieter ones. No airflow? All I know is the little motor burned up about a half hour after I started using it. I hope for your sake mine was just due to go from old age. Mine was based on something one of the mags had, and like yours it had a “design” for airflow.

I now have a very low decibel Fein. Hardly need to wear ear protection for it, and that thing is an awesome performer. Just in case it was due to lack of air flow.

They need plenty of air cause the vacs do get hot but this shouldn’t stop you from making a quieter vac box.
I mounted an extra bucket to the side of mine and set my cyclone bucket into it so it all moved together.
Nice project and O so handy!!!

Ya, you certainly need to ensure your vacuum is cooled by the air being sucked in thru the hose and not by a secondary fan. If it’s the latter, this box would kill it.

I have been lusting after a Fein but for the price, this works just as well and I get another work surface to clutter up :)

I enclosed mine as you did with drill press, scroll saw and grinder on top. I’m sure it gets warm. I spent the extra $12 and got the 3 year, no questions asked warranty from Lowes (taped to the inside of the cabinet so I know where it is) so I drive it like I stole it. It’s almost 2 yrs old and no issues. I figure if I run it hard for 3 years I’ve gotten my money’s worth.

I am really thinking about putting mine out side… No collection needed at all. Just blow it out into a compost pile in the back. Just a thought.

I heard that, benches all the way around the back and sides of my 32×24 shop space, 3 benches, 3 assembly tables, not to mention all the flat tables on my tools, and almost every trip out there I have to clean some horizontal space off, or I run out of places to clutter up. I have no understanding of the work flow in a small shop, or one without a lot of flat space.

The Fein only looks expensive, once you have one you will wish you had dropped the coin earlier.
