I like to build with barn boards and reclaimed wood so I spend a lot of time sanding and wire brushing the dust and debris off of the boards before I begin a new project. My shop was always covered in dust and I found I was breathing a lot in (really dislike trying to work with a dust mask on). My father-in-law had an old furnace fan he donated to the project and the end result is in the pictures. There are two furnace filters on each end that filter the air before it is brought into the fan and pushed out the front of the unit. I have since put the unit on castors and put a grill cover on the front that directs the air to the ceiling. That will help circulate the warm air in the winter. The unit is working well and the dirt and dust collected on the outside filter suggests it has been a success.

Great project, you’ll like how it cleans the air in your shop.
Think about pulling air in from the top, if its near the height of your other tool surfaces.
You could have a downdraft sanding table as well…

Not sure what your filters are able to remove, but I would guess that you would want to do better.

It is the really fine particles that are the most dangerous so if you are not removing them with your filter(s), you are actually just recirculating the more dangerous fines back into the air.

These filters are not cheap but are the key to good air quality. You are looking for filters that will filter down to 1 or 0.5 microns. Give them a call. They are super helpful.

I hope you find this information constructive and I do not think it would take much to adapt your design, if you so choose.

Hey jamerand, i have been using one like this for about 6 yrs now and keeping the filters changed is very important. But it does a great job, you will love it..

Have your say...
