Due to momentum, the air blowing out of a fan will have much more speed than air getting sucked in. This is one reason to mount an air filter nearer one end of a room and have the intake on the short end. Similar to your proposed location for your cleaner. Though another line of thinking is to have the air filter intake located as near the dust producing equipment (table saw?) as possible.

I would move the fan to the west side near the northern end and have it blow due south. Its air will blow south, into the SW corner. It will have to turn towards the east, be drawn into the air cleaner and get blown north. Forced to turn west, towards the fan. Round and round it goes.

It’s not that large a space and with a cleaner, fan, and AC unit, air will be moving around pretty good. However, there will always be dead spots and while the air filter will help a lot to keep the air clean, you’ll still get dust settling around the shop.

The dust around the shop is an issue even when you are not making dust. Just moving around the shop will kick dust up. And FYI, based on my particle counter by an order of magnitude, sanding operations are the worst for creating dust.

As for the AC getting circulated, that’s a non-issue. The very cold air out of the unit wants to fall down and will spread out throughout the shop. Though of course a breeze always makes things feel cooler, so the fan is good and the air filter just more.
