I started out getting a used furnace fan but kept putting off using it because of it’s size hanging from the ceiling in my small shop. This filter made from 1/2 inch MDF uses a fan from an old stove top unit that seems to do an adequate job. H 9 W 21 D 28 1/2 12 D on the bottom. It would be easy to take 3 or 4 inches off the D if wanted. Still have the furnace fan and will make a floor unit when I get a couple other projects done to make room for it.

She’s a beaut Clark! I might have to copy your design. I just acquired a few motors and fans for this purpose.

How big is the shop and how many CFM does the fan provide?

MedicKen, my shop is 16×25 and I don’t know the CFM.

Great idea, the installation of the filter at an angle give you a lot bigger filter, without subtracting from the
overhead space, will have to keep this one in my file. Thank you for sharing.

Thanks for sharing. At first I thought that you exhausted thought the roof, but was happy to see that your design does not require any roof penetrations. Do you find that this unit is sufficient on its own, or do you still supplement dust control with a vacuum system?

WRAAdesign, I do have a Jet w/cyclone that I use with my planner/joiner. I tend to not hook it up with other equipment because of the hassle, so I added this filter to help with what seems to be an endless amount of dust I make.

I’ve had my eye open for a furnace or blower to do just this type of project. I’m hoping to happen across a snail blower or what not and get it cheap. No luck so far. The commercial ones are not cheap. Good, but not cheap.
