Reverse flow allows the heat from the fire box to pass through a chamber to evenly diffuse in the cooking chamber before the heated air and smoke are exposed to the meat. The heated air and smoke bath the meat as it changes direction back toward the exhaust near the fire box, thus the term reverse flow.
Reverse flow is not limited to horizontal smokers. Some vertical smokers like Humphrey's and Backwoods also utilize the reverse flow principles.
