Dru-B-Q™ UDS Fan Deflector – 540mm for 44gallon Ugly Drum Smoker. Now an adjustable one piece deflector system is all that you need to tune your UDS smoker. Sits directly on the charcoal basket, or if possible mount approx. 100-150mm” above the basket. To adjust, simply bend the tabs up to increase flow and custom tune your ugly drum smoker. The fan deflector is the solution for UDS smoker heat management. Helps restrict flow & mix the air which prevents burnt food from direct heat, stabilize, equalize and balances temps. Easy indirect cooking on your drum! Allows for precise draft control and tuning. Fixes the inherent flaw of un-controlled heat just below the meat. No more flare ups when you open the lid!
