Dryer-Ell 90 Degree LT90

This 90-degree dryer-ell fitting is a native Revit family designed for mechanical ventilation and dryer exhaust ductwork systems. The Dryer-Ell 90 Degree LT90 is a standard mechanical elbow fitting designed for 90-degree transitions in vent or duct runs. It features a smooth, curved geometry to minimise airflow resistance and lint accumulation, which is critical for dryer exhaust performance. The component is finished in a neutral white, suitable for exposed or concealed installation within utility rooms or wall cavities. Its robust construction ensures compatibility with standard rigid duct diameters, providing a reliable connection point for residential or light commercial ventilation layouts. The geometry is clean, functional, and prioritises technical efficiency over aesthetic form.

The download is a 573 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.

In Revit, this fitting functions as a loadable family that can be integrated directly into mechanical duct or pipe routing workflows. Professionals should load this component into the project environment and map it to the appropriate system classification. It can be used to manually connect duct segments or as part of a routing preference set to automate transitions. Ensure that the project units are correctly configured to match the sizing parameters of the family for accurate scheduling and coordination.
