非气密式动物隔离设备运行现状调研分析
Investigation and analysis on operation situation of non-airtight animal isolator
摘要：
通过对20台非气密式动物隔离设备的现场实测数据进行汇总整理，结合我国目前用于评价非气密式动物隔离设备综合性能的相关标准进行分析，发现设备静压差（负压）为20～50 Pa时，即可满足气流流向的要求，送、排风高效过滤器检漏测试基本可满足标准要求，建议使用方对设备定期进行维护和检测。

Abstract：
Summarizes the field test date of twenty non-airtight animal isolators, analyses and evaluates the comprehensive performances of non-airtight animal isolators with the relevant criteria. The results show that the air flow direction can meet the standard requirements if the static pressure difference (negative pressure) is 20 to 50 Pa, the leakage test of supply and exhaust high efficiency particulate air filters can also meet the requirements. Recommends users to regularly maintain and test the equipment.
