   You just need some sort of backdraft damper to prevent the air from flowing backwards into nonoperating units. Caution must be taken against lint accumulation, which can lead to blockage and fire. There MUST be a code-approved commercial solution to this. There are limits to duct length, too. Don't forget you can run ducts to the roof too! (Is this a nice-looking factory? Is there such a thing?)

   *Geoff - Check out http://www.fantech-us.com. You can argue the pros and cons of putting fans or dampers in dryer ducts, but if you have to, they make very high quality fans and the best backdraft dampers I have seen.

   This is probably beyond the scope of single family house building, but does anyone know of a ducting system that allows for more than one dryer to be vented at a time? I am currently converting a turn-of-the-century brick factory building into an apartment building. We would like to avoid individually ducting the dryers for each of the units. To do so means we would have to drill 4" holes through 16" of masonry, disturb the appearance of the outside of the building with the vent covers, etc.
