Museum Grade Air-Tightness

Air change is defined as the ratio of air supply into a display space in relation to the volume of display space.Air exchange rate (AER) or leakage rate of display cases dictates the flow of air (a mixture of gases including water vapour, pollutants and particulates) in and out of internal display space.The air exchange rate will effectively influence the display space of display cases to buffer external environmental conditions and limit the ingress of dust and externally generated pollutants.In addition,the finally acquired micro-climate values and the control precision of climate system are also very related to the airtightness of display space. Well airtightness is achieved by consistency of display cases' structure, the high fabrication precision for each parts, the dedicated sealing aluminum-alloy extrusions,the glass bonding technology,the door sealing strips and the performance of opening system.Integrated well airtightness of museum display cases ensures minimal air exchange between internal display space and external atmosphere to be not more than 0.1 times per 24 hours.
