About two months ago, I picked up a Dust Deputy and attached it to my shop vac to help control dust while woodworking. I let the 5 gallon bucket under the cyclone fill up completely before emptying it the first time and you see the results below. The bucket is mostly full and the shop vac has almost no trace of dust in it! I did take the filter off anyway and blow it with compressed air to clean it anyway, but it didn’t need it. If I had sucked up this much sawdust without the Dust Deputy, I would have easily gone through two shop vac filters and those things aren’t cheap. I’m very happy with this setup!
With recent woodworking projects, I have been putting more effort into keeping the dust under control. That has been going well, but it means I’m going through filters on the shop vac very quickly. You can only knock the dust out of them so many times before they aren’t usable anymore and they fill up with dust very quickly. I’m also nervous about burning out the motor on the shop vac because it can’t pull air through the clogged filter.
Full shop dust collection systems are expensive, but I purchased a simpler solution. The Dust Deputy is a plastic contraption that spins the air before it enters the shop vac. Heavier particles fall into a 5 gallon bucket and clean air enters into the shop vac to get the final cleaning from the filter. There’s nothing too fancy or complicated about it. It’s just science. And boy does it work well!
After more than a month of use, my 5 gallon bucket is about half full and the inside of the shop vac is almost perfectly clean. You could run a white glove across the filter and barely get it dirty. That shiny new filter is going to last a VERY long time. Another bonus is that the 5 gallon bucket is much easier to empty than the shop vac container.
If you think about how many filters you’re going to buy to keep your shop vac working smoothly, the cost of the Dust Deputy isn’t too bad. This is definitely one worth considering if you use your shop vac for dust control.
