Has anyone tried one of these to convert a single stage dust collection unit into a two stage? Seems like a decent deal with the sales price.

for that money you can get 2 dust deputy’s which DO for sure work great.
just my thoughts, notice that they are 2” inlet/outlets, not 4” as needed for a dust collector, so this is more for a shop vac type set up in which case the dust deputy works extremely well.

they do look nice though, I almost bought one last year.

I use one of these on my dust collector, designed to work with metal garbage can.

Works pretty well, big stuff goes in can, dust goes to dust collector. The can empties very easily.

I didn’t catch the 2” inlet/outlets so thanks for the heads up on that. Where are you able to find the Dust Deputy for half that price? Is this the one you are referring to?

sorry, I guess I mis-spoke. I was referring to the small dust deputy as I thought you knew the Laguna had the 2” inlet. I just checked and the small dust deputy has gone up in price since I bought mine. If you are looking to convert to a 2 stage, I would definitely consider the 4” one that you have in your link, as the smaller units have performed great for my shop vacs.

That would work great for a shop vac. I am using the small dust deputy for a shop vac and it works great. I have the plastic Super dust deputy for my dust collection system that is hooked up to a HF dust collector.
16 gal would be too small for using it with a dust collector. Would fill up very quickly.
When I use my Dewalt planer, I fill up a 20 gal trash can very quickly.

In industrial systems we often use what we call a drop out box.
This is simply a chamber with a large enough cross section area to let the incoming air with chips and dust expand and slow down before re-accelerating back into a duct going to the fan/filter. About 95% of the dust and 100% of the chips will drop out of the flow and be deposited in the bottom of the chamber.

In a 4” duct system the chamber can be a 30 gallon trash can. For a 6” duct system I would rather use a 55 gallon drum.

Another way to do the same thing is one of those “cyclone lids” that places like Rockler and Woodcraft sell to fit on top of a trash can.

I just point these alternates out because they don’t cost you as much static pressure loss as a true cyclone.

The cyclones, like the Dust Deputy, will do a superior job of catching most of the particulate material before it ever gets to the collector but this comes with a cost. The cyclone reduces the available static pressure and that causes a reduction in air flow.l
