Investigation and analysis on operation situation of non-airtight animal isolator

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.
