Hanging an air filter from ceiling

[Whiskeymike]

I'm making a shop air filter from a large squirrel cage and motor, some filters and a sheet metal box I'm fabbing. I'm trying to figure out the best way to hang it from the ceiling. I have ribs above to connect to. I could do uni strut or home made equivalent, all thread, chain, ???. Any thoughts on the best way?

My neighbor had one of those nice woodworking air filters and he attached with unistrut with some threaded rod to lower it a bit.

That's what I'd recommend.

I threaded eye screws 2-1/2" into the joists above, one at each corner, then used a short length of chain at each corner.

As above

All thread. What are you hanging it from? You mention ribs. Wood, steel? If it is a metal building and you are hanging from the purlins be sure to attach to the side, not the bottom flange. Also try to stay as close to a frame as possible.

When the blower kicks on, there will be some pretty good "twisting" action going on with it ....hanging from chains. JMO

Uni-Strut and All-Thread

Sliding barn door track anchored to ceiling, then used barn door wheels to connect to my air filter and modified a cord real to hang heavy electric to it in the middle. Have a 2x2x6 air filter hanging in ceiling that slides 40' side to side to get closer to area that needs filtering

It doesn't sway from blowing the air around? That was my concern with chain.

Metal building, 2 pieces of c channel run length wise of building about 4' apart. Thanks for the tip of going into the side. I was going to go into the bottom, but can see how that would be bad.

Unistrut across joists, hooks on one end going into loops on the dust unit so it can hang while I connect the all thread on the other end.

Rope ratchets work well.

No sir. It doesn't move at all. The chain is pretty tight at all corners.

How tall is your ceiling?
In a previous house I was doing a lot of woodworking in the garage.
I also had limited ceiling height. What my plan was to put it in the attic right above the garage.
Since you are building it anyway I would mount the fan in the attic with ducting going to the garage ceiling for inlet and outlet

The Jet air filter I have comes with 4 eye bolts for chains OR it has 4 metal brackets that you can use to screw it directly to the ceiling when you remove the eye bolts.

I wanted mine up as high as I could so I used the metal brackets. In this pic you can see two the holes where they attach to the metal frame near the eye bolt

I wonder if that can be mounted vertically into attic with ducting back into garage? Where is infrared eye? Side or front?

I have a jet and a delta, neither of which are homemade, and I just used lag type eye screws. The commercial units have such low horsepower that they do not move at all on chains.

It's a 14' peak, but it's a metal building, so no attic. I'd like it to be pretty high though. The chains seem like a cool option.

Eye hooks...works great.

My home built one hangs from chains and eye bolts, a bit of a shake on startup part of which is the tug on the switch chain but other wise it just hangs there 16 feet off the floor.
