NACA Air Inlet Ducts
NACA ducts (also known as NASA ducts) are the most efficient, lowest-drag way to direct cooling air where it is needed. These ducts are molded from tough, high-impact black or clear plastic. Each duct has a wide flange for riveting or epoxying in place.
The Small duct is designed to accept our 2.5" ID duct hose. The Medium and Large sizes are designed to accept our 3" ID duct hose.
