I found this site while googling around and he uses Latta equipment. There are pictures of the setup at:

I don't know if this is a usual setup (from the site):

I have to insure that from start to finish these filters do the job. So with the large 28 sq. ft. filter captures 99.97% of all dust down to .5 microns. To increase efficiency, we installed a 30 gallon drum with a cyclone lid ahead of the vacuum system. It captures 95-98% of the dust from the sanding machines right into a plastic bag, while the rest is caught by the filter and drops into a 9 gallon pan. Plenty of suction and great filtration. I can set up this unit in the house and leave no contamination. I have used the dust containment system on a number of jobs, and to date, I have observed no airborne dust. None on the windows, walls, or myself.
