Tube Fan Extract Unit

This Revit family provides a parametric tube extract fan unit designed for industrial or commercial HVAC ductwork integration. The component features a robust, cylindrical housing designed for inline installation within mechanical ventilation systems. It consists of a primary central drum with tapered transitions to smaller circular connection ports on either end. The geometry is clean and functional, prioritising schematic representation within BIM models. The visible form suggests standard industrial steel construction, typical for extract or supply air handling units. Parameters are indicated for defining the radius of the connection points, allowing for flexible sizing to match standard duct diameters in various MEP design scenarios.

The download is a 246 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 into a Revit project, snapping it to existing ductwork runs. The parametric radius controls allow the user to adjust the port sizes to match specific duct dimensions, ensuring accurate connectivity. Once placed, the element can be scheduled via the mechanical equipment category. Users should verify that the connector settings align with the project's system requirements for airflow and static pressure, maintaining consistent metadata for downstream analysis and clash detection during the design development phase.
