Flat Oval Spiral Ductwork offers the appealing look of regular round spiral but with the abilities to provide airflow in tighter space restrictions, like rectangular duct such as low ceilings. Flat Oval Ductwork also offers a higher technical standard that usually smaller fabricators are not able to supply.
