In all tests, ducts are first pressurized and the leakage rate measured at a test pressure. In some

geographic areas, that test if followed by a depressurization test. Readings are usually written down but

may have to be recorded over a prolonged period and the data logged. Retrotec FanTestic software

performs that task and provides a formatted report. Data can be logged automatically or entered

manually.
