About this asset

A compact heat recovery ventilation unit Revit family representing the Zehnder ComfoAir 155CM with circular duct ports and clearance bounding geometry. The model depicts a low-profile rectangular MVHR casing engineered for restricted ceiling or soffit voids. It features four lateral round duct connections configured on opposing faces to facilitate supply and extract air routing. An integrated digital control interface with button details is modeled on the primary vertical fascia alongside recessed vertical access panels for filter maintenance. The body showcases a neutral grey sheet-metal casing with molded composite caps and spigots. Below the main enclosure, an explicit wireframe volume designates the required lower access and maintenance clearance space.

The download is a 860 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.

Designed for MEP design workflows in Revit, the component can be integrated into ceiling or service cupboard coordination models. Users connect standard circular ductwork directly to the specified supply, extract, exhaust, and outdoor air spigots to maintain continuous air system connectivity. The integrated clearance volume ensures clash-free coordination against structural framing, electrical trays, and suspended ceiling grids during Clash Detective reviews.

Engineered primarily for multi-family residential apartments, high-performance homes, and light commercial office spaces, this unit supports decentralized mechanical ventilation with heat recovery strategies. Building services engineers and architectural coordinators routinely deploy these compact ceiling units when detailing utility cupboards, hallway drops, or kitchen plant zones. It serves as a vital specification element across mechanical duct layouts, spatial coordination drawings, and MEP handover packages requiring accurate MVHR equipment sizing.
