Vertical 90 Degree Duct Elbows

Vertical 90 degree duct elbows are widely used in manufacturing plants, woodworking shops, metalworking facilities, foundries, and warehouses. Any industry requiring industrial ventilation, dust collection, or pneumatic material handling systems relies on these fittings to route ductwork efficiently through facility layouts.

Vertical 90 degree duct elbows are typically fabricated from galvanized steel, stainless steel, or aluminum, depending on the application. Galvanized steel is standard for general ventilation, while stainless steel is preferred in corrosive or high-temperature environments, and aluminum is chosen for lightweight installations.

Select a vertical 90 degree duct elbow based on the diameter of your existing ductwork. Measure the inside or outside diameter of the duct pipe at the connection point. Standard sizes are available to match common duct diameters. Contact Duct Incorporated for guidance if your application requires a specific or less common size.

Yes, vertical 90 degree duct elbows are well-suited for dust collection systems. They are designed to handle particulate-laden airflows while maintaining consistent velocity through the turn. Proper elbow sizing and smooth interior surfaces help minimize pressure drop and reduce material buildup within the collection system.

A standard elbow has a shorter centerline radius, which results in a more compact fitting but higher airflow resistance. A long-radius elbow has a larger radius, producing a gentler airflow curve, lower pressure drop, and reduced turbulence. Long-radius elbows are generally preferred in high-velocity ventilation and dust collection applications.

Vertical 90 degree duct elbows are installed by connecting each end to the adjacent duct sections using slip or drive connections, mechanical fasteners, or flanged joints depending on the system design. Joints are then sealed with duct sealant or tape to prevent air leakage. Always ensure the elbow orientation aligns with the intended airflow direction before securing.
