A grey double-door ventilation unit carries pictogram labels in German and English for "Filter", "Wärmetauscher / heat exchanger" and "Ventilator / fan", plus airflow arrows. A "EUROVENT CERTIFIED PERFORMANCE" sign sits on top, in front of a wood-effect wall with a board of grilles and a brochure rack.
