Where should airflow velocity measurements be taken, with respect to a filling line or other aseptic processing areas?
Recommendation Airflow velocity measurements should be taken at locations where meaningful and reproducible results can be obtained. This typically at a distance of 15-30 cm from the filter face. Rationale for Recommendation The primary reason for airflow velocity measurements in unidirectional airflow areas (e.g, area where products , product contact packaging components, and product contact surfaces are exposed) is to ensure adequate airflow to protect […]
