Wirlybird Turbine Ventilator 300mm

This Wirlybird Turbine Ventilator 300mm is a Revit family featuring a roof-mounted extraction unit for efficient air ventilation. The unit consists of a spherical, multi-vane turbine head mounted on a cylindrical base, which is attached to a rectangular flashing plate designed for roof integration. The design follows standard wind-driven ventilation geometry, utilising vertical vanes to facilitate air exhaust from internal spaces. The model presents a clean, utilitarian aesthetic typical of industrial roof hardware. All components are consolidated into a single assembly, ensuring consistent proportions for a 300mm diameter duct connection. The geometry is simplified for efficient BIM performance while maintaining the necessary visual representation for roof plan and elevation documentation.

The download is a 379 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.

This Revit family is designed for placement on roof surfaces, utilising face-based hosting to ensure alignment with sloped or flat roof planes. Users should load the component into the project environment and snap it to the desired roof element. Ensure that the associated ductwork or shaft opening is aligned with the circular base of the unit. Parameters can be managed within the properties palette to adjust placement elevation or visibility settings for various project documentation stages.
