The Zehnder CLRF vent is made from smooth and odourless HDPE. It is suitable for wall and ceiling installation in conjunction with round grilles or valves with air volumes of up to approx. 45 m³/h. The air volume for the grille is regulated at the vent via the Zehnder ComfoSet flat 51 airflow regulator. The vent is connected to the distribution system via the Zehnder ComfoTube flat 51 ventilation tube. The vent is sealed using the seal provided and locking slides to ensure an airtight connection to the distribution system. The installation depth is variable. The air volume regulation for the grille can be adjusted at the vent as well as airflow of the supply and extract air valve.
