A while back I posted a Shop Filtration unit I had built. It can be found here

That unit had an old bathroom fan in it which was rather noisy and I was very limited in how good of a filter I could put in it since is had very little power. I have wanted to change the blower in it for some time. I finally purchased a Dayton 2 speed blower thinking I could modify the housing and install it. I ended up building a whole new housing to accommodate the bigger blower. I also added a timer that will shut it down after a selected time and made 2 slots for back to back filters.
The new unit still has the ability to either recirculate for filtration or I can close the sliding door and open the window for ventilation. The blower is almost silent and I can now run it all the time without the noise. The new blower also moves a lot more air. Thanks for looking

I like it. I need to do something like this for my little shop.

Way better than what I have, for sure! (I have a 20” box fan I got at a yard sale for $3 with a filter strapped to the intake side, hanging from the garage ceiling over my work table…. tackytackytacky! Slightly better than nothing, in combination with the shopvac, but the filter gets well filled, so it’s doing some good.)

That is a nice installation.
I used a recycled furnace blower built into a rolling cabinet which has my sharpening station on the top. I can roll it closer to the source of dust or more often I use it in double duty to circulate the heat from my wood stove.

A good thing to help keep that nasty dust outta the lungs.

Very nice! I especially like the built-in timer!

Nice work. How does the circulation work instead of just blowing it outside? I know you mentioned a sliding door but I don’t see how the filtered air makes it back into the shop.
