Visitors study the Thesslagreen display under the slogan "Wentylacja domu z oczyszczaniem i nawilżaniem powietrza". A panel for the "Centrala wentylacyjna AirPack4" sits beside wall-mounted controllers, while a white duct system with a central purifier runs along the far wall of the all-white stand at Forum Wentylacja 2019.
