Axial Flow Extract Fan

This Revit family provides a standard axial flow extract fan for mechanical ventilation systems in commercial or industrial projects. The axial flow extract fan is a compact, cylindrical unit designed for inline duct integration. Its geometry features a central tubular body with flanged ends for secure connection to standard circular ductwork. A small lateral junction box is positioned on the exterior casing to represent the electrical connection point. The design is purely functional, prioritising clear geometric representation for MEP coordination and clash detection. It includes simplified graphical symbols for plan and elevation views, ensuring that the component remains lightweight within large-scale building information models while maintaining accurate physical dimensions for spatial planning.

The download is a 297 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 can insert this component directly into Revit mechanical systems by snapping it to existing duct runs. The family is designed to facilitate standard MEP workflows, allowing for easy connection to ductwork segments. Users should ensure that the airflow direction, indicated by the integrated arrow, is correctly oriented during placement. The model is suited for early-stage design coordination and detailed construction documentation, helping to verify clearance requirements for maintenance and access to the fan motor assembly within ceiling voids or plant rooms.
