Circulation Fan Kit for Electric Smokers
[CIRFAN]

Best thing I ever did was install this fan in my Pit Boss digital 3, keeps a constant temperature improved my smoker by leaps and bounds. Smoking/drying jerky or slim Jim's require precise temperature control increasing 10 degs an hour the fan really helps. I installed mine in lower right corner, my rain cover will fit over the control box and my racks are wire for airflow.
