The deterioration of stored or exhibited cultural artifacts is caused not only by insects, mold, and dust but also by oxidation from the air and corrosion from harmful gases such as sulfur dioxide. This damage is markedly accelerated in high-temperature and high-humidity conditions. In addition, sudden changes in temperature or humidity can warp absorbent historical items and lead to damage. Fresh and recycled air supplied to storage areas can contain dust, SOsub{2}, NHsub{3}, COsub{2}, and other contaminants, which should be removed through the installation of an air purifier.
Fan Filter Unit (Circulation)
This device uses a fan to take in and pressurize external air and air in the exhibition room, and supplies it through an air filter
Types of available air filters
This long-lasting, pleated filter removes particles with a diameter of more than 5 μm.
This filter has a medium collection efficiency for particles with a diameter less than 5 μm.
