About this asset

This grey metal round duct horizontal tee fitting Revit family models standard three-way branch junctions across building mechanical air systems. Visible in both wireframe line work and shaded volumetric views, this component represents a standard three-way round duct tee fitting. The geometry comprises a straight horizontal main run coupled with a perpendicular round branch intersection. Rendered in a neutral grey metallic finish, the body displays clean cylindrical curvature engineered for seamless inline airflow routing. The simple, unadorned form features circular opening profiles at all three connection ends without superfluous detailing, providing clean visual representation for MEP layouts.

The download is a 82 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Engineers and BIM coordinators can load this RFA file directly into Autodesk Revit projects to complete round ductwork networks. When routing horizontal ventilation runs, the component inserts at three-way intersections to divide or combine supply, return, or exhaust air paths. Connectors snap accurately to adjacent round duct elements, enabling consistent mechanical system assignments, fluid flow calculations, and collision detection within ceiling voids and technical risers.

Designed for complex building service layouts, this horizontal tee serves commercial offices, educational facilities, healthcare centres, and industrial plants. It integrates smoothly above suspended ceiling grids, within exposed warehouse soffits, and through mechanical plant rooms where circular ductwork distribution is required. MEP modelers and coordination consultants use this asset alongside straight round ducts, dampers, flexible duct runs, and diffusers during technical design and clash detection phases.
