Home Made Portable Air Filter

My friend Kevin in Etown made this for me, he comes up here about every other weekend and we usually go out to eat and come up with weird Horse stuff to do lol. He owns the other Articulating 4x4 much like mine.

He runs an HVAC business and got an old gas furnace they just took out of a house and modified it. He made an inlet filter box on the return that holds up to 4 20 x 20 filters and he also put one on the output side. The output elbows can be put in any direction to put the air where you want it. He brought me 36 filters to get started and see how long they last. It will also make a great fan when it gets warmer out. It should help a whole lot with the messes I make around here. Going to try it out here in a little bit if it stays quiet around here.

There's a 3 speed fan switch coming for it this Wed so the speeds can be adjusted on the fly, then it just needs to be painted red lol.

It doesn't get it all but it gets a lot. I've been playing around with where the output elbows are and found if I point them to the rear corner where the tire changer is it makes the air whip back around toward the big door where I paint and back to the filter. Will give that setup a try tomorrow and see if it gets more of it before it hits the floor.

The filter system is good, I had all 5 filters in it for the test run and the one pulled out in the pic is the last of 4 closest to the blower. There's also hardly no paint floating around in the shop like a haze even with everything closed up completely while I painted. It is also making the paint dry a lot quicker just from all of the air movement. I like it for sure but need to experiment with it a little more.

That should keep things allot cleaner, How many CFM?

I'm not sure GT, it was a 90K BTU high efficiency gas furnace in a 2K square foot home. It sure blows a lot of air, too much for just using it for a cooling fan that's why I have the 3 speed switch coming today.

The switch came in today, now I have 3 speeds.

Does the wiring look ok Kev? It's color coded and everything lol.

Looks good

Not that you come out of hiding very much but you need an avatar dude.
