About this asset

Designed for commercial kitchen mechanical stacks, this Revit family provides a roof-mounted downblast exhaust ventilator assembly in grey metal finish. The assembly features a domed downblast cowl housing mounted on a squared roof curb base plate. Below the curb connection, an integrated vertical duct riser transitions down into the kitchen canopy plenum box. Geometry is modelled cleanly with standard sheet metal profiles, representing the circular fan cowl, structural mounting plate, vertical exhaust shaft, and transition canopy section over primary cooklines. The simple grey utility finish accurately conveys manufactured galvanised or spun aluminium roof machinery, maintaining neat representation across shaded, wireframe, and hidden line project views.

The download is a 266 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.

Load this.rfa component directly into your building model to coordinate MEP roof penetrations and food service extraction systems. Position the unit above commercial cookline equipment, aligning the duct stack to penetrate roof slabs or curbs cleanly. Mechanical engineers and architectural technicians can link the family into overall plant room coordination models to check vertical clearance against ceiling heights and external parapet sightlines.

This asset suits back-of-house hospitality projects, staff canteens, ghost kitchens, school cafeterias, and restaurant dining buildouts where commercial kitchen ventilation hoods are required. Pair it with stainless steel cook ranges, fryers, prep benches, and grease ducts during schematic design or construction documentation. It meets typical search phrasings including kitchen exhaust fan, rooftop downblast ventilator, restaurant ventilation unit, and commercial hood exhaust assembly.
