I will start this by stating I do not know how effective this is at cleaning the air for my lungs. I built this to capture most of the fine dust that floats around and falls on any surface long after a project is over. To protect my lungs I wear a dust mask. That being said I built one of these in the past and it is very effective at keeping the shop clean.

I got this design from Sandor Nagyszalanczy’s book Woodshop Dust Control: A Complete Guide to Setting Up Your Own System

I used leftover scraps of 3/4” ply to make the box. It is made to fit a 12” X 12” Air Filter. The box is joined with pocket screws. The fan is a Dayton and is 665 CFM. I bought mine on ebay, but they can be found on Grainger.com.

Here is a photo of the parts ready to be assembled

A Dry Fit

Some large circle cutting action

I first had to set up my circle cutting jig on the bandsaw

I then used the circle that was cut out to mark the center and to create an outline for the rough cut with the jigsaw

After that I used the other part as a template to clean up the circle on the router table

Next is assembly time

how often do you have to clean out the fan box? or does most of the dust stick to the filter?

which way is the fan blowing air? (I don’t know much on this topic) I’m assuming sucking air in through the fan and blowing it out through the filter?

Thanks – cool design!

Most of it sticks to the filter, so I don’t recall cleaning the box very often, but you could easily clean the box with a shop vac. You would be amazed at the amount of dust the airfilter will collect.

The fan blows away from the filter, sucking air through the filter.

Is this used for ‘general’ air dust collection, or do you use it in a ‘power’ carving environment? Either way, great project thanks for sharing -

I use it for ‘general’ air dust collection. I plan on hanging it from the ceiling. I have never done power carving, i understand it produces alot of fine dust. I am not sure how this would hold up or if the suction is good enough.

Nice! I love the simple but effect design. I bet you could also stick another “finer” filter on the other side to collect the smaller particles if you wanted, but for the purpose of this project it may not be needed. Great job

thanks for the info – i guess thinking about it, you wouldn’t want to be blowing the dust through your fan because then it wouldn’t last very long. Makes sense to suck through the filter (duh). Thanks – very cool! On my to-do-list

I read it is better to put a filter like this close to the ground. Dust will settle toward the floor and having it high will draw dangerous dust into the air for you to breathe in before it gets filtered.

That’s why you should wear a dust mask or respirator also, this is only to help not to fully remove all dust from the air.
