So, you just make this and install it in some out of the way place in your shop and it takes care of everything? I have a shop that is a long rectangle, about 14 x 24 feet in size. It seems to me that if I make one of these and put it on just one end of the shop that it won't be very effective for gathering dust from the other end. I could be wrong. I read that I can use attic fans as a source of the internal fans. Would this work and be effective in my shop's particular size?
