well i was inspired by a few of you guys who made air filters to go ahead and make my own. I call it the franken-filter.. because it looks so effin ugly.
i used three rotron fans as suggested by someone else,
and because a common problem was the weight of the air filter, i decided to build a frame and then layer it with acryllic.. well i did this partially, but then decided it wasn’t sturdy enough and layered it with 1/4” birch plywood in some spots

i used a good amount of wood glue/silicone sealant to make sure there were no leaks.
i’m pretty proud of the toggle switches for some reason, and also the slide out doors to hold the filters into place.

i haven’t fastened it up to the ceiling yet, but when i do i’ll post a pic of that. let me know what you guys think of the ugliness.
behold.. franken-filter!!

Ugly doesn’t matter if it works. Just throw some paint on it.

Nice job!

nice job

built one myself a couple of years ago, used a furnace fan for the blower it really makes a difference in the ammount of small particles floating around in the air especially when sanding

Ugly is a matter of opinion…..if it keeps the dust outta your lungs it’s a beautiful thing.

This is a very interesting project. I am sure that you built it for far less than it would have cost to buy a “pretty” one. Take the money you saved and put it into a new tool.

Nice project. Thanks for the post.

Hey that looks familiar! It’s amazing how much air those high volume rotron fans move, isn’t it? You did good! Good job on the toggles!

Like Gary said; Throw some paint on it. Then turn it on and as you see the dust disappear it will get prettier, and prettier.

you could always call it “the Fugly Fan”

Nice job though and if does what it is supposed to do , then you can call it
“Mission Accomplished” and breathe easy !!!

Great job. I’ve got a commercial one but I’d like to make a couple more because of the size of the shop and the air movement. inside.

I’m looking for discarded furnace blowers to save on the cost.

Ok I am pretty dumb …what is a ROTRON FAN …is that a fan used in industrial applications, AC units and etc?
Are they expensive …where can I get one or more …looks like
Eddy the Flow used 3 fans ?
I like the idea and I know i can make an uglier one than that …lol

Gator, I am not sure where they use Rotron Fans, it’s a brand…’s an axial fan like you have in your PC’s, but a lot more powerful. I used 3 in mine as well when I built mine a couple yrs ago. You can see it up close here…

I like it! If and when I get the time to get back to the garage, one of these would be a very fitting project to start with. Thanks for the post.
