So, today I put my order in for the Grizzly hanging air filter that’s on sale. I just replaced my Shop-Vac & DD with a 3HP DC, so I feel like I’m moving in the right direction.

My question now is, where to hang this unit. My shop is a 2 car garage, and my space is 22×22. However, there is an I-beam that spans the garage, and extends about 5-6” down from the ceiling. Also, I have a single 4” DC hose run on the ceiling, which could be repositioned if necessary, but obviously, the I-beam is going nowhere.

Does the unit need to be hung a certain distance from the ceiling to account for that I-beam? Also, with this in mind, where would be the optimum placement, given the super awesome shop layout picture below.

The brown box is my bench. The green box is the DC. The long grey box is the I-beam (the picture stinks, its actually centered, with about 10’ on either side). The two white boxes are hanging florescent lights (4’). The bottom half of the picture is where the garage doors open, so I can’t mount there. I store all of my lumber on the lower half of the drawing. Almost all of my dust-producing tasks, with the exception of the occasional routing tasks at the bench, are performed under those florescent lights, and my machines are all on mobile bases.

I placed mine closest to the most dust making machines in my shop. Its located in a corner where I felt like the air could circulate best. My dc does a good job catching chips from the jointer planer and tablesaw but I don’t have any dc port on my bandsaw yet. Lots of fine dust from there. Its also nearby the outfeed table which I do all my sanding on.

That’s my take on the situation. Put it close to the area that creates the finest dust.

Like stef said, place it over the machines that make the most dust. Keep the return at least 4-5 from the wall so the air isn’t bouncing off the wall and blow more dust around. Can you put it between the garage doors with the intake facing the lights?

Like this? I probably could, and if I stuck it between the I beam and the wall w/ doors, the box would have approximately 4’ between it and the wall. My concern with that would be that the exhaust would shoot right into the wall. I could lower it a bit and move it clos to the I beam, so that the majority of the intake was below the bottom of the I-beam, it would give me just about 6.75’ of clearance between the bottom of it and the floor. A little low, but I don’t do any work right there because there’s a vertical support column. I could place it right next to that column and it probably would not get in the way. I know they say to put it along the longest wall, how well do they work in the middle of the room?
