Some of the links on this forum allow SMF, at no cost to you, to earn a small commission when you click through and make a purchase. Let me know if you have any questions about this.
I have thought about this and noticed that a local meat shop has one of those fancy commercial units inside his store. when he opened the door, you could see all the smoke go towards the vent pipe, which leads me to believe that if you install a small fan to create just a little draw it should pull all the smoke outside. I work in a dyno lab testing engines and we always have the testcells setup with a little draw to them. Keeps people from getting sick from CO poisoning, so I would be comfortable running a smoker like that.
