Mechanical ventilation unit modelled as a Revit family, featuring a faceted grey housing with four top circular spigot duct connections. The model represents a compact, upright mechanical ventilation with heat recovery (MVHR) unit. It features an angular exterior casing with chamfered upper shoulders, rendered in a neutral uniform grey finish typical of powder-coated steel or moulded polymer construction. Four circular duct collars emerge vertically from the top panel, arranged in two paired sets to accommodate supply, extract, intake, and exhaust runs. The front service face includes faceted relief detailing, recessed access grips, lower fixing apertures, and an integrated bottom inspection recess for filter maintenance clearance.
The download is a 1.1 MB 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.
Designed for MEP coordination within Autodesk Revit, this family can be loaded directly into mechanical models or multi-disciplinary federated files. Users can position the unit in plant spaces or utility cupboards to test spatial clearances, align ductwork branches directly to the top spigots, and coordinate service zones against structural elements. The compact geometry ensures efficient viewport performance without inflating project file sizes.
This ventilation asset suits low-energy residential schemes, single-family homes, multi-unit apartment developments, and light commercial projects where balanced mechanical ventilation is specified. Specifiers commonly locate it within utility rooms, basements, laundry zones, or dedicated service cupboards. It pairs naturally with distribution manifolds, rigid or semi-rigid ductwork, ceiling diffusers, and acoustic attenuation modules during technical design and spatial clash detection stages.
