There are other cooling solutions too, there was a recent thread that used a peltier setup, and others that use ice chests, etc… but I like that this is an air purifier on top of all that, given your dust needs.
Those kinds of tents are definitely not insulated, so it might be a struggle to cool it quickly, and you’ll be hoovering up 200 cfm through the glowforge, so you might not be out of the woods on dust entirely… it’s a challenging setup you’re in. These things probably have equations you can use to figure out exactly how quickly all the air will turn over, but you figure it’s probably 10x10x7, that means you turn over the volume of air inside the tent every three minutes.
It might be smarter to use a cover on the gf when not using it – like this:
and then use a more directed AC option like here:
That way you’re not struggling to AC the entire tent, but you still get a filtered air feed to the unit and the cover can keep the dust off.
I might still use a 10x10 tent just to keep dust out in general, plus a cover for the unit, and then a directed AC like that.
