Downblast Exhaust Fan Floor Mount

This Revit family provides a floor-mounted base for a downblast exhaust fan, featuring a cylindrical housing with integrated mounting tabs. The assembly consists of a cylindrical housing unit designed to support a downblast exhaust fan mechanism. Constructed with a robust metallic profile, the unit features a circular top and base plate, with external mounting brackets positioned at the perimeter for secure floor attachment. The geometry is clean and functional, prioritising technical accuracy for BIM coordination. Reference planes are visible in the family environment, indicating clear parameters for sizing and orientation within a mechanical layout. The design is intended for standard industrial or commercial roof-top or plant-room mounting applications where vibration isolation or secure fixing is required.

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.

In Revit, this family is intended to be placed on a structural floor or equipment pad. Users should utilise the provided reference planes to align the unit with ductwork centre lines or mechanical equipment schedules. Since this is a mechanical component, ensure that the family is loaded into the project environment and placed via the systems tab. The geometry remains lightweight, allowing for efficient placement in large-scale mechanical models without significantly impacting overall project performance or rendering speeds.
