This Revit family is a double width double inlet (DWDI) centrifugal fan, a high-tech mechanical component for HVAC system design. The unit features a robust steel housing enclosing a high-capacity impeller system designed for industrial air movement. The assembly is mounted within a rigid square steel frame, providing structural support for the cylindrical fan body. Visible design elements include the central shaft, bearing support, and the circular intake ports characteristic of a DWDI configuration. The geometry is clean and functional, prioritising mechanical accuracy and standard connection interfaces. This family provides a clear representation of the fan's physical footprint, essential for spatial coordination and clearance checks within complex mechanical plant rooms or ceiling plenums.
The download is a 307 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 family is intended for placement within mechanical projects using the Equipment category. Designers should utilise the provided connection points to align the fan with ductwork runs. The model maintains a simplified geometry to ensure project file performance remains stable during large-scale MEP coordination. Users can manage visibility via sub-categories to toggle between detailed 3D geometry and schematic 2D symbols, facilitating clear documentation in both plan and section views for construction phase drawings.

This asset is suitable for mechanical engineers and BIM coordinators working on industrial, commercial, or healthcare facilities where large-scale ventilation is required. It is commonly deployed in plant rooms, air handling unit (AHU) enclosures, and basement ventilation systems. When integrating into a project, it pairs effectively with standard ductwork families and vibration isolation mounts. Professionals searching for this component typically look for 'DWDI fan', 'centrifugal blower', or 'HVAC mechanical equipment' to ensure accurate spatial planning and duct routing coordination.
