  • Method for leak testing an environmental enclosure
    Patent number: 7727765
    Abstract: Methods and apparatus are disclosed for leak testing the ventilation system of an environmental enclosure using a gas that is naturally present in ambient air, such as nitrogen, oxygen, argon, or carbon dioxide, as a tracer gas. In one embodiment, a gas filter capable of filtering all of the tracer gas from the air flowing through the filter is installed in the ventilation system. Testing is performed by operating the ventilation system to cause outside air to flow through the filter and into the enclosure so as to establish positive pressurization inside the enclosure. A gas monitor placed inside the enclosure is used to detect for the presence of leaks in the ventilation system by monitoring the concentration of the tracer gas inside the enclosure.
