Industrial Ductwork

"Excellence is not an accident. It is the result of high intention, sincere effort, intelligent direction, skillful execution and the vision to see obstacles as opportunities. The John W. McDougall Company personifies this ethic."

Frank Stallwood, President
EJCON Corporation

Industrial ductwork has been the foundation of our company since 1938. John McDougall, Sr. started a small fabrication shop in Nashville to fabricate ductwork for all of the industrial heating and air conditioning systems for which the company was a manufacturer’s representative. Since then, we’ve continued to grow and diversify but we are proud to maintain our leadership in the industrial ductwork fabrication and installation market. We know that ductwork is just as important as large complicated industrial systems because if the ductwork isn’t perfect, the systems can’t work properly.

McDougall Co., Inc. fabricated and installed two 18” diameter and one 32” round duct lines, connecting over 40 pickup points inside the plant, connecting three dust collection systems, providing the interior of the plant with a dust-free environment. Also, we fabricated two 40-ft stacks and a 60-ft stack that is 42 inches in diameter and installed the entire dust collection system and duct.
