Kevin, Thank you...I think that would be a great idea since I don't want to pull my ceiling mounted system down. Since, I know you are familiar with the EX 21, is there a way that I can put the puffer on the other side so it blows the other direction. Right now, the puffer is puffing toward the (right) wrong side and I cannot put the fan on that side. I am limited on where I can put my scroll saw. Thanks again.
