Hello everyone,
We have installed a controlled residential ventilation system Wolf CWL 400, and I want to create a transom ventilation horizontally, above the door leaf.
How many millimeters do I need to mill out over a length of 80cm (31.5 inches) to allow the required air volume to pass through? Is there any calculation formula for the air cross-section?

What more can I say about this? It is basic HVAC knowledge. If you plan to have closed doors, you need to provide transfer grilles or similar elements.
The airflow between rooms in the supply air, transfer air, and exhaust air zones of a house or apartment must not be blocked by closed interior doors. All rooms must have non-lockable and properly sized transfer openings. These passages become necessary in systems where air is supplied to the rooms from outside through outdoor air inlets (decentralized) or via supply air vents (centralized).
How these are implemented is up to the homeowner or the contractor. Whether the gap under the existing door is sufficient can be calculated or determined from tables/diagrams.
