HEPA Filter Leakage Testing, Airflow Distribution Testing and Flow Rate Verification
HEPA (high efficiency particulate air filters) filters and HEPA filter integrity are critical to air filtration systems in industries including pharmaceutical, semiconductor, food, and nuclear. HEPA filters are most effective when used at their rated airflow resistance and face velocity, and various standards have been implemented for certification and in-situ qualification testing of HEPA filters.
