How to Improve Shop Vac Dust Collection

Like most people that work in a garage, do construction or woodworking, dust can build up and you may use a shop vac to help collect the dust.

But how can you get the shop vac to get more of that minuscule dust?

We’re here to help.

The shop vac’s primary design is based around vacuuming smallish sized particulates, usually dirt into a canister, with a motor drawing air through a filter while trying to evacuate that air from the canister. Overall, the design works pretty well for most of the uses asked of it. They will even vacuum up liquids.

Then, there is the general clean up from all the woodworking activities that do not have the direct ability to collect dust. Drilling, jig saws, all the various hand tools and since I consider all the power tools to be efficient with shop vac DC in the 85-90% chip and dust collection range, there is all the waste that escapes that needs to be cleaned up there as well, So you see, without even discussing the high volume uses on the full sized dust collection system.

Shop Vacs Can Only Do So Much

The shop vac is really carrying a lot of the load here. For years, shop vacuums have been supplied with hoses and accessories that offer limited capability when it comes to cleaning proficiency and dust collection. We have researched and tested many hoses, wands and accessory attachments, selecting just the best of the best, and are now offering what we feel are the best shop vacuum upgrade accessories available anywhere. They are very affordable, and you can configure these tools and hoses anyway you like, to best fit the needs of your workshop or garage.

Two objectives most of us has in mind is minimizing a mess, and trying to keep the air in the shop or garage relatively safe to breathe. The problem inherent with shop vac design is that we want it to give us filtered air from the very same filter we are clogging with fine dust, and as the filter fills with dust and clogs, the ability that the motor has to move air through that filter becomes greatly reduced. It has been determined that while it is difficult to completely isolate the filter from dust, we can scrub a great deal of the waste from the air stream before it gets to the filter. By doing this we can run the vac with higher flow efficiency, and deliver better quality filtered air for longer periods of time. This is most productive.

Over time, a number of different solutions have been offered for particle separation in shop vac systems. They run the gamut of high cost – high efficiency, to low cost – low efficiency, and all work to some degree or another. The nice thing about them is that they remove a great deal of waste from the air stream before it gets to the vacuum, and helps keep the filter cleaner and flowing air at higher volumes, longer.

My thoughts have been for a while, that if there is any way you can help clean the air a shop vac is pulling without the material reaching the canister and filter is helpful.

Shop Vac Dust Collection: An Attachment is the Solution

Enter the trash can cyclone lid from Woodriver.

It fits tightly to the container it is meant to seal. It has an inlet and outlet that fits common shop vac hoses. Its inlet is positioned in the right location to direct inlet waste stream around the perimeter of the container in a cyclonic manner. It has an outlet positioned in the center of the lid that takes air from the container in a way that keeps interference to the cyclonic airflow to a minimum.

After a few test, more and more debris got sucked up easily by the trash can cyclone lid.

So much so that it really got some of the tough dust that otherwise would have still been there.

There you have it!

Getting an affordable shop vac combined with a trash can cyclone lid can really help to suck up more dust.
