IMHO – If you want smallest footprint, Do not use the existing square tube duct work & filter bases.
Just use conventional blower on top of cyclone design, and duct outlet air to side and down into 2 filters stacked with a dust tray on bottom. It might feel like a waste of fancy hardware, but need to trash it if you really want smallest foot print.
All you need is square flange to round tube adapter, short piece of round outlet tube, and a 90, then make some plywood mounting rings to support weight of filters, and you’ll have a conventional 2 column cyclone dust collector.

There are many ways to adapt square flange to round tube.

1) Oneida sells square to round adapters for blowers. Believe the Grizzly G0562/G1030 3HP units used either a 7 or 8 inch inlet/outlet? Regardless, measure and call Oneida to get right one.

2) Spiral tube and Norfab also sell square flange to round tube adapters, but tend to be more expensive than Oneida

3) If you have a local sheet metal fab shop, they can also easily make an adapter.

4) Once you are resigned to not using the existing duct, you could also cut off the flange and small section of duct, and make your own round tube conversion from some sheet metal.

5) One last idea: New Grizzly 3HP cyclone units have a square to round port adapter on them, and is listed in parts list. Might be able to call Grizzly with dimensions of your square port, and get an actual OEM adapter like the one used on current G0441 cyclone?

PS – I have not attempted this conversion, but I plan to do it.
Still looking for used 3HP dust collector at right price.

Best Luck.

Capt…great ideas. I have no issues at all abandoning the arms & collars to save up on real estate. I like your last idea of Grizzly cyclone square to round adaptor. Going to have to go measure existing square exhaust outlet and see if they have same measurements.
