    Standard Duct and Fittings

    Image of System. Front orientation. Exploded view. Duct and Fittings. Standard Duct and Fittings.
    Deliver air for a range of HVAC applications, including exhaust and dust collection. Our basic duct, the round shape creates smoother, more efficient airflow than rectangular and oval duct. The male end is slightly smaller than the female, so sections join without clamps or tools.

    Exhaust Vent

    Intake Vent

    Cover vents with caps that let air in or out.
    Exhaust Vent—A built-in damper allows air to escape while blocking backdrafts, rain, and snow.
    Intake Vent—Only fresh air enters though the screen—no debris or pests allowed.
    Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.
    Lightweight Aluminum—One-third the weight of steel, aluminum ductwork is easier to handle during installation. Like galvanized steel, it resists rust in wet environments but won’t last as long.
