I am starting to think about designing an building a downdraft table. All the ones I have seen seem to have a squirl cage type blower and a set of filters. I was thinking that since I have all this cyclone DC power, why not run ducting to the DC system over to the downdraft table instead of a blower an filters? That way there would be no need to clean and replace a separate set of filters. Anybody have other thought on this idea? Also, could someone point me in the direction of some downdraft table plans or any other ideas that might be helpful in designing a downdraft table.
