Ok I wish i didn’t have to worry about return air, but this is a Small Shop space! Although often i have to open the “barn” door on the end to allow room for planing, ripping, etc. So sometimes on bigger jobs the return venting wouldn’t be an issue. I just wanted to consider any ideas for a sort of return air filter. How do the huge industrial shops do it? With their huge collection systems outside, they must have something similar as to what I want, just on a slightly different scale;)
