Calculating cleanroom air change rates for iso 1 5 in cleanrooms with unidirectional airflow air exchange rate is calculated by air velocity sampling. It s suggested that in cleanrooms with unidirectional airflow patterns iso class 1 5 air exchange rates can be calculated by average air velocity. This post addresses air change tables and calculations in iso 2 iso 3 iso 4 and iso 5 cleanrooms with unidirectional airflow. In an earlier post on air change rates for cleanrooms we outlined how to calculate cleanroom air exchange rates for iso 6 iso 7 and iso 8 cleanrooms.
