Wall vent F100 dB internal part

F100dB internal part with coverplate #210 for wall mounting. The vent is designed to provide a continuous airflow into the building/house. The internal part is delivered with a standard filter (dust/insect) and a front cover with condensation protection. The vent can easily be open/closed with the pull cord. In order to ensure correct airflow and to retain good air quality it is important to keep the filter clean. We recommend to wash/replace the filter 1-2/year. The Standard filter is washable (use a gentle soap/detergent). The Pollen filter and Environmental filter should be replaced with a new filter.
