I'm thinking of putting a curtain around my 3-tier brewstand so that the combustion gases, particles and pollution are better captured by my 470 cfm through wall ventilator. I'm thinking that the curtain would reach from whatever curtain rod I use to the bottom of my brew pot or so, which is about 8 inches off the floor. My source of fresh air would be outside the curtain and the idea is for the fresh air to pass under the curtain.
The curtain rod would be in a U to surround the brewstand. Is there a way to do this so the attachment hardware does not interfere with opening and closing the curtain?
Any recommendations, thoughts, photos, gotchas?
