I have a 11’x’ 22’ single car garage with a 7.5’ ceiling.
I just ripped down all my sheetrock, sealed the air gaps, and insulated at every wall.
My house is a split-level, so I have 2 beams that cross my garage, and those 2 beams separate my garage ceiling into 3 sections of ceiling.
I have 8 outlets that are 120v and 2 outlets that are 240v.
I have a model 50-875 Delta air cleaner that measures 24’x 28’x12” and am trying to figure out where to mount it. I have two 4’ T-8 fluorescent shop light fixtures that I am not married to, but in the past I had them mounted across the width of the front & rear sections of the ceiling along with a standard cheapo ceramic single light bulb with a pull chain in the middle section that I am not married to either, along with my garage door opener. I have used the air falter sitting on the floor a few times, but it has been sitting in my basement wasting away the dollars I spent on it.
At the front of my garage I am going to build and mount cabinets to hold all the “stuff,” and my Delta contractor’s table saw (which is on a base with wheels) will be under the cabinet. Also against the wall of the front of my garage will be my stacked rolling tool chest & drawers.
Should I mount the air cleaner in the middle section of my garage ceiling? Picking up air from the front half of the garage and returning the air out the rear towards the garage door, or will it be effective mounted facing across my garage where the air is picked up from the house wall side and blown out towards the outside wall?
I have a 6hp Ridgid brand shop-vac with a fine filter that I will use to collect dust from my table saw, joiner, router and compound miter saw via some ducts I will install – I only use one machine at a time since it is a small garage-shop and the shop-vac.
I’d really like to hear your suggestions and your experience.
Thank you for your help!

The air cleaner should be parked on the ceiling if possible.
Do you have a delay feature for shut off?
Just a point…...

Yes it is corded, and O can plug it into the same outlet that is on my ceiling for my garage door opener.

I’m concerned with placement. I can change the lighting fixtures and where they are mounted, my concern, which I guess I should have made clearer is that the beams on my ceiling will effect intake and/or output of air from the air cleaner which will effect its efficiency.

Don’t mind the mess I am still working on the walls and insulation.

There is nothing wrong with making a box to hold it against the side walls above a cabinet or bench. That way it won’t bonk your head and if you place it well it might help with air circulation in the space.

I’m going to experiment with some different placements but I have one I built on my own, which is a downdraft table but it’s got a very large surface area and is on the ground.

I am going to make another one that I am going to place on the ground as well. and a third on the other side of the room but higher up.

I’m hoping to make the room air circulate towards the ground as opposed to having the dust drawn up to the filter on the ceiling.
My thinking has been, if it can get into your shop filter on the ceiling, you’re already breathing it in as it’s passing on the way up.

Mounted on a side wall sounds like a good idea- I don’t have to worry about beams blocking the air flow.

I don’t have room for a full shop with my Harley and my SUV in the garage, so a downdraft table for sanding and routing doesn’t seem possible unless it folds and can then be stored on my table saw with the air cleaner. My wife wanted this house I didn’t- I wanted a house with a much bigger garage.

I couldn’t leave it on the wall when not in use because I have a full-size SUV and it would be in the way when opening the car doors, so I would have to put it on top of the table saw when not in use, and then on the wall when needed. any ideas about hanging it sideways?

Hang it from the ceiling, 1/3 of the way down a long wall, about a foot away from the wall. The intake should be on the short side of the long wall. This is the configuration Delta used to recommend when they had customer service. And I recommend a Dust Deputy to go along with that shop vac. It will keep your filter clean and keep the air flowing.

Is there any way you can mount it high, and have it stay over the hood of the SUV. Probably to the side so you don’t hit your head on it constantly? Maybe that would still meet the 1/3 length setup intheshop suggested.

I have a Jet filter hanging in the middle of my one car garage space. Though I have 9 ft ceilings, and it’s a closed off garage bay of a 3-car garage. So no car goes in it. Center of room is what Jet recommends, but I question whether this is best. Many seem to think that to the side is best.

I think having so much room on the intake side allows that air to slow down too much and the dust settles out of the air before it gets sucked in. Not sure why being to the side of a room would be better (or worse), but I do think keeping the intake side shorter may be a good thing. I may give that a try sometime.

Oh something else. My space is similar in size to yours 12’ x 24’ and I have 8 dual T-8 fixtures (16×4 ft tubes total). I love all the light. Virtually no shadows. I can’t imagine trying to work with just two of these and a single light bulb.

You really can’t have too much light. At least for cutting and assembly. Adding more T8 fixtures is trivial since you can just daisy chain them end to end. Add a bit of 1/2” conduit between them where needed.

Maybe a bit trickier in your case working around the beams.

I read somewhere you should hang the filter on a long wall so as to create a stream of air that circulates around your shop.And or over one of your most dust producing machines.I like mine over my lathe.

So. I’m thinking that I should put up eye screws in the left front end of the middle section of the garage ceiling, but eye screws with hooks on the air cleaner, and just hang it up when I need it.

I also could hang it permanently at the same height as the garage door opener and the air cleaner will be just safely above my SUV when I park it in the garage.

If I suspend it from the ceiling will the air cleaner sway in a dangerous manner?

I suspend my Grizzly air cleaner near a side wall, centerline, jack chained to the ceiling. It does not sway when in use. The dust you see chest level is not the dust you should be most concerned about. It’s the micron dust that you can not see that floats in the air. Hence, wherever you put the air cleaner height does not matter as these dust microns do not follow gravity physics all too well :)
If you will rely on your Rigid shop-vac for your chip collection, please do get a Dust Deputy attachment. It will save your Rigid filters from wear & tear.

I am definitely going to get the Dust Deputy.

Concerning swaying of the filter. You can ensure that won’t happen by putting the anchors in the ceiling further apart than the attachment points on the filter. That way the chain (if you’re using chain), will have a slant to it.

In order to sway, one side has to lift while the other drops. Not impossible, but it requires a rotation force to do it and there’s nothing to provide that force.

If the the chains hang straight down, then it can just swing like a pendulum. It’s also easier to twist this way.

However, I doubt any of this would be a problem.

In my case, my trusses above the ceiling are on 24” centers and the filter attachments were something like 18” apart so I ended up with this geometry by default.

So. Hang I will hang it by chains.

I I will look for 2 extra anchor points and have the air cleaner side hanging from 2 more anchor points at different ages and that should keep it steady.
