Airflow Management in Cleanroom Facilities


Monday, November 1, 2021

5:30 PM to 6:00 PM - Online Networking

6:00 PM to 7:30 PM - Technical Webinar followed by Q&A

Event Summary

Clean spaces are developed for a variety of applications including pharmaceutical, healthcare, aerospace, microelectronics, food and beverages. The main goal of cleanroom application is to maintain high level of cleanliness in the spaces to minimize cross contamination. Air is the primary carrier of heat, moisture, and contaminants in cleanroom facilities. The flow path of supply air plays an important role in determining the air velocities, air temperatures, particle concentration, and flow path of airborne particles. These factors in turn determine the level of cleanliness and distribution of contaminants in the space. This presentation will first cover basics of cleanroom classifications, and source of contaminants, and then, will focus on the importance of HVAC configuration on airflow distribution and resulting flow path of airborne particles in cleanroom that affect the contaminant removal effectives. In addition, this presentation will also cover role of Air Changes per Hours (ACH), demand control ventilation, cleanroom airlocks, and dynamics of laminar diffusers in cleanrooms.
