About this asset

This AVAB roof exhauster is a Revit family component featuring a robust metal housing designed for efficient industrial ventilation. The AVAB Roof Exhauster is a utilitarian mechanical component designed for exterior rooftop mounting. Its geometry comprises a primary cylindrical housing for the fan mechanism, topped with a protective cap to prevent moisture ingress. A rectangular lateral housing is integrated into the side, likely containing the motor and electrical connection point. The assembly sits on a square base plate, providing a stable footing for roof curb mounting. The form is strictly functional, finished in a neutral grey, reflecting its role as a standard piece of industrial HVAC equipment.

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.

As a native Revit family, this component is intended for placement on roof plans or 3D roof topologies. Engineers should align the base plate with the roof curb and ensure the connection point is correctly oriented for ductwork integration. The family is lightweight, ensuring minimal impact on model performance. Users can utilise the parameter controls to manage mechanical data, flow rates, and electrical requirements, ensuring accurate scheduling within the building information model and coordination with secondary MEP systems.

This roof exhauster is suitable for industrial, commercial, and healthcare projects where mechanical ventilation is required. It is commonly specified for warehouse facilities, manufacturing plants, and large-scale office buildings requiring roof-mounted extract systems. Professionals can use this asset during the design development and construction documentation phases to represent mechanical plant locations accurately on roof layouts. It pairs effectively with standard HVAC ductwork families and roof curb components, facilitating precise clash detection and MEP coordination during the technical design stages.
