Double Width Double Inlet Centrifugal Fan Housing

This Double Width Double Inlet (DWDI) centrifugal fan housing is a technical Revit family for industrial HVAC mechanical systems. The component represents a standard DWDI centrifugal fan housing, featuring a robust steel construction designed for high-volume air movement. It includes a central shaft assembly, internal fan housing geometry, and a rectangular discharge flange for ductwork connection. The model is built with clear geometric references for width, height, and radius dimensions, facilitating precise integration into complex mechanical plant room layouts. Its clean, functional aesthetic reflects standard industrial engineering practices, focusing on structural integrity and airflow efficiency within a compact footprint suitable for integration into larger air handling unit assemblies or standalone fan setups.

The download is a 287 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 load this family into a Revit mechanical project and connect it directly to ductwork systems using the defined discharge flange. The family supports parameter-driven adjustments for dimensions, allowing users to scale the housing to match specific equipment schedules. It is best managed within a dedicated mechanical equipment category, ensuring consistent tagging, scheduling, and visibility control across project phases, from initial design development to detailed mechanical coordination and final construction documentation.
