About this asset

This Revit family provides a roof-mounted axial fan exhaust unit, featuring a cylindrical housing atop a square mounting base. The unit comprises a primary cylindrical exhaust housing topped with a domed cap, supported by a square-profile mounting curb base. The geometry is clean and functional, designed to represent standard mechanical roof ventilation equipment. It includes visible reference planes and dimension parameters within the Revit environment, indicating its potential for adjustment to meet specific project sizing requirements. The model is rendered in a neutral grey, suggesting a standard galvanised steel or powder-coated metal finish typical of industrial HVAC components found on commercial or industrial building roof levels.

The download is a 225 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 family directly onto a roof plan or 3D view in Revit, utilising the face-based hosting capabilities to snap the base to the roof surface. The provided dimension parameters allow for quick scaling to match specific manufacturer performance data or duct sizing requirements. Users should ensure the family is assigned to the correct mechanical equipment category to enable proper scheduling and tagging within the project browser, maintaining consistency across the MEP model documentation.

This exhaust unit is suitable for mechanical ventilation layouts in industrial, commercial, and large-scale residential projects. It is typically placed on roof plans during the design development or construction documentation stages to indicate air extraction points. Professionals searching for this component will likely be coordinating HVAC systems, roof penetrations, or equipment schedules. It pairs effectively with roof-mounted ductwork, electrical connection points, and curb mounting details, ensuring that all mechanical services are accurately represented within the overall building information model for coordination purposes.
