Before and After: Modifying a Fan into a Dust Collector

When I moved into my current house, the owner left a rather large furnace blower fan that he had mounted to the ceiling in the garage. It comes in very handy when the weather gets warm or I want to move the air around.

I decided to build a box around the blower and attempt to get some of the dust out of the air. Even with my Delta 50-760 dust collector, some of the dust get airborne and I wanted to catch as much as I could.

Nothing fancy here. 1/2 inch particle board shell with a 1×2 pine frame on the inside. 36” long and 15” wide, 21” tall. The tricky part was enclosing the current hanger system so I didn’t have to take the blower down to put the case on. A couple notches on the top panel did the trick. A helping hand from my wife while I put the screws in the top panel and tadaaaa!!! The picture frame clips on the front and back allow me to put a filter in both places but gives me easy access to the inside or to change the filters themselves.

Not perfect, a little rough, but I can already see some of the dust being caught on the inside of the filter. Yeeeaaaaahhhh! Now, back to the fun stuff!!!

An excellent concept, well executed. Nice.

I keep thinking about that “box fan + furnace filter” idea. What? Twenty bucks?? It’ll do SOMETHING, anyway.

This unit prob moves alot more air than a 600.00 unit. I have plans to build one but of course, haven’t yet. Very nice job! Happy breathing!

I have done the same thing, only I put filters on 3 sides, it works pretty good.

I’ve been keeping my eyes open for an old furnace blower to do the same thing. Nice work!

That’s what I like, making use of what you have to be more efficient and healthy. Inexpensive and works great.
Well done.

I have a squirrel cage I pilfered off of a furnace I replaced….this is why. Great job.

Woodsmithshop, the filters are a good idea but do not provide enough resistance. This can cause the motor to freewheel and overamp. If you ever notice the air flow surging as opposed to being constant this why. An enclosure like this would solve that and actually increase air-flow.

I did the same thing except I put it on wheels so I can roll it around and aim it at where I am working. A great relief on a hot summer day. These fans are quiet and move a lot of air. I made it easy to take the filter out so that I get more air movement if I just want the fan effect. I didn’t take pics during construction but I will post pics of the finished project tomorrow.

hanging it from the ceiling is a great idea too. It keeps it out of the way. nice job

I should have said 4 filters instead of three, sorry. I have not noticed any surging I’ll watch for that.

Wow – you didn’t even take it down! Very nicely done! But…you’re not going to stain it? ;-)

What can I say, I have a burly woman for a wife. She power-lifted the box while I put the screws into the top!

Booooyyyaaaaahhh!!

Actually she’s a little thing, but tough as nails!! Couldn’t have finished up without her!

after looking closer it appears you can turn it in different directions. is that so?
