If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers may be channeled into a “common main duct.” The individual ducts should enter the bottom or side of the main duct at an angle not more than 45° in the direction of airflow and should be spaced at least 46-1/8” (117.16 cm) apart. The main duct should be tapered, with the diameter increasing before each individual 14-inch (35.56 cm) (minimum for gas, electric, or steam dryers) duct is added.

IMPORTANT: No more than three (3) dryers should be connected to one (1) main common duct.

NOTE: The individual ducts traveling from each dryer up to the common duct must not travel more than 15 feet (4.57 meters) including the 45° entry elbow into the common duct and the 90° elbow outside the dryer allowing the duct to travel vertically. These individual ducts must be a minimum of 14-inches (35.56 cm). If the ductwork exceeds these limits, the ductwork size must be increased proportionally according to the number of elbows and the length that has been added.
