If you were worried about it you could build a frame around it that
takes at least 4 24x24 white furnace filters. Not the 99 cent ones but
some better ones. I mentioned at least 4 filters because you do not
want the air flow restricted too much by some small filter area.

Thanks for the reply, Jim.

My thought is that the gable fan would obviate the need for an ambient
air filter/scrubber. Even with the best collection at the machines I
have, from what I've read sofar, there could still be some v.fine dust
in the air. In particular: how much sanding do I do, and how well can
I collect the sanding dust? Is my DC unit closeted (not planned to be
right now)? And I'm still looking for a good way to hookup a chopsaw
to the DC to capture max dust.

So, if the gable fan can refresh the air in my shop every... 10-12
minutes? I gotta think that's at least as good a benefit as an ambient
air filter. 'Course, in the wintertime... :*)

Anyway, I'm gonna install it also for the heat exhaust reasons it's
designed for (Sierra foothills toasty summers); I'll just have to check
it now and then to see if it's accumulating much dust.

gable vent is not going to see much dust.
