Belt Drive Centrifugal Roof Exhaust Fan

This Revit family provides a belt drive centrifugal roof exhaust fan, featuring a robust, grey metal housing for industrial ventilation. The unit features a low-profile, square base mounting curb that transitions into a cylindrical fan housing. Designed for roof-mounted applications, the geometry is utilitarian and compact, reflecting standard specifications for belt-driven centrifugal exhaust systems. The model includes the essential form of the motor cover and the exhaust discharge section, providing necessary spatial clearance for mechanical coordination. The grey finish is indicative of a standard galvanised steel or powder-coated metal exterior. This component is modelled for clear representation in MEP plans, sections, and roof layouts, ensuring accurate spatial integration with structural and architectural roof elements.

The download is a 348 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 as a face-based component onto roof surfaces or structural planes within a Revit project. It is designed to host duct connectors at the base, allowing for seamless integration with mechanical ductwork systems. Users should manage the visibility settings within the object's family parameters to toggle between coarse, medium, and fine detail levels, ensuring the model remains lightweight during the design development phase while providing necessary precision for construction documentation and coordination with other MEP disciplines.
