Introduction: My Take - Shop Air Filter
I'm old. I like to recycle. I need an air filter to keep the dust down in my small shop. I found a box fan.
I often do a lot of sanding and that generates a lot of dust that gets all over everything. I know there are commercially available shop filters and I know this is not the most efficient method but it works and that's all I need.
This builds on the published projects of many other folks, to whom I am grateful. This is not to belittle their work, merely to show how I did it. If it helps someone, that's good.
As always, be safe ALWAYS USE PERSONAL PROTECTIVE EQUIPMENT AROUND DANGEROUS MACHINERY.
Step 1: Make a Plan, Gather Materials
I made a simple sketch to get in my mind how it would go together and what materials I would need.
20" Box Fan - I found one curbside
Assorted pieces of wood - I had a couple of pieces of laminated flooring for the sides and the rest was offcuts from the shop pile.
Filter - an inexpensive furnace filter. If this works then I'm good. If not, it will be easy to modify the frame to add a filter and then consider getting more expensive one BUT from what I have read, this seems the most economical for the money.
Step 2: Prep and Build
After testing the fan, I washed it to remove dust and dirt. Then sanded and primed the metal parts.
I prepped all the wood frame parts and fastened them to the fan and each other.
Step 3: Ready for Use!
Finally I reattached the front guard and inserted the filter.
I can set it on the floor next to where I am sanding or I can use the handle for a couple pieces of rope and hang it from the rafters if needed.
