I always use the "gentler" Festool sanders with dust collection, but it should work alright. I think that not using DC would probably shorten the life of the abrasive.
FYI, you don’t have to use a Festool CT to use the sanders. You can use a run-of-the-mill shop vac with a step-down adapter for the hose and a pigtail adapter to attach to the tool. Even a simple compact vacuum like the Home Depot’s $20 “Bucket Head” would suffice.

Anyway, sidebar on sanders… I had the opportunity to use the RAS this weekend, to strip my daughters' outdoor playhouse (to prep for restaining).
Since my sisters was helping I gave her the the RO90 with the vac to do the interior, and I used the RAS without any DC to do all the outside
No problem eating up the material. It threw dust everywhere, but the machine didn’t seem bothered by it. I wore a good quality dust mask, or it might’ve been bad news.
Later, I used the RAS to sand the floor, and I had the vac attached for that work. I was *stunned* by how good the dust collection was with the movable sweep. My sister was shocked also (especially as we’d been used to the dust cloud for much of the day). Time to get a “Y” adapter for the CT.
I bought the RAS during the recon sale, and it was sort of an impulse buy given the price and everyone saying these are terrific. Well, it earned its keep yesterday and I’m buying another box of sandpaper! (I used only THREE sheets of 80g sanding the entirety of this playhouse, over the course of 3 hours).
