Electric fan circulates air and efficiently adsorbs gases harmful to cultural properties Effective Improvement for Air Environment Simply installing it at the edge of the display case to efficiently improve air quality. It is unnecessary to move exhibits when installing it and to open the display case for ventilation after the installation. In addition, the airflow speed controller in 10 levels allows operation at low airflow speed that does not adversely affect the exhibits. Indicator shows when to change the filter By checking the "acetic acid indicator or ammonia indicator" from the window on the top of the device, you can visually determine when to replace the acetic acid filter or ammonia filter. This prevents incidents such as a prolonged lapse of time with reduced adsorption performance. Operation Time Settings Continuous operation or intermittent operation in 24-hour cycle can be set, allowing for adjustment of operation and shutdown according to the exhibition hours and installation environment.
