Proper fan tracking requires the accurate measurement of the entire airflow system including supply and return air, outside air and relief air, all of which are required to maintain proper air balance and thus control the building pressurization. Airflow measurement, which can be achieved through fan tracking, is a much more effective and accurate means of maintaining building pressurization when compared to static pressure measurements made throughout an entire building.
The products below are commonly used for this application.
