Box Fan Mod

For almost two years, I have been using a box fan with a filter taped over the inlet. Well, today I decided to do something about the set up.

In less than 20 minutes, I had a couple of pieces of scrap plywood screwed and glued to the fan. The filter simply drops in from the top. No more duck tape! :-(

I operate it with a remote (Christmas lights type) so I can start it when I need it and not have to climb over all sorts of stuff to get to it.

Today, I had it set on the table saw wing so it could help capture whatever dust flew up in the air.

Sometimes it is the simple things that make me the happiest. :-)

Nice and simple and should help clear the air!

These are a great idea. Cheap and very effective to move the air around and filter it out. What took you so long? Ha ha.

I need one NOW !!! Spray-finishing a bunch of small parts.
What’s the filter size?
Are you pushing or pulling air through the filter?

John, 20×20. Box fan from Wally World. :-)

Pulling the air through the filter.

That was four pieces of scrap I didn’t have to throw away. heh heh.

DD, I have been using the fan regularly, just had to tape the filter on to the frame each time I changed it. $20 fan, and it does work to filter the air. I also have a dust collector and a small size air filter hanging from the ceiling (one car garage/shop).

John, You can see the filter size in his first photo, it’s showing 20” X 20” X 1”
I had to flip the shot!

Thanks for the filter size and the “pulling” instructions. I was guessing that I would want to catch gunk in the filter before it hit the fan. Guess confirmed. :)

I have used one of these hanging in the ceiling of my shop for a few years. I had filters on the infeed and outfeed side of it. It worked very well, in my opinion. I kept the filters clean tho, and made sure they never got too full of sawdust. I even had one at my lathe specifically for sanding exotic woods. However, While re-doing my shop these past 2 months, I took the ole box fan down, because I have intentions of replacing it with an air purifier. I picked up a squirrel cage off Craigs list a month ago. I’ll get round to building it one o these days.

Roger, it is running right now. :-)

I also have one of the small Grizzly air filters hanging from the ceiling. Lately, I have the fan sitting on the table saw wing when I am using it.
