Cleanrooms are the backbone of critical manufacturing industries such as semiconductors, pharmaceuticals, biotechnology, and electronics. These highly controlled environments are designed to minimize contamination and ensure product quality. However, even with stringent protocols, cleanroom failures can and do occur, leading to costly yield losses, regulatory setbacks, and compromised product integrity. This article explores the root […]
Retrofitting HVAC systems in cleanroom environments is a significant investment aimed at improving air quality, energy efficiency, and regulatory compliance. However, the true measure of success lies in the system’s ability to maintain stringent environmental controls post-retrofit. Facility managers and HVAC professionals must validate that the upgraded system meets cleanroom standards, prevents contamination, and supports […]
Introduction: Proving Cleanrooms Perform as Designed Designing a cleanroom is one thing. Proving it performs according to ISO 14644-3 test methods is another. From airborne particle counting to airflow visualization studies, ISO 14644-3 ensures facilities meet their classification and regulatory expectations. Part 1: Core Test Categories Airborne Particle Counts: Calibrated using PSL standards. Airflow […]
Introduction: Why Standards Define Cleanroom Success Without measurable standards, cleanrooms would be impossible to validate. The ISO 14644 series provides the global benchmark for cleanroom classification, defining how many particles of specific sizes are allowed in controlled environments. From semiconductor fabs to pharmaceutical sterile suites, understanding and applying ISO 14644 is essential for compliance and […]
Introduction: Why Airflow Matters in Controlled Environments Cleanrooms are engineered spaces where air quality is tightly controlled to protect products, processes, and patients from contamination. At the heart of every cleanroom design lies one critical factor: airflow. In semiconductor fabs, pharmaceutical sterile fill-finish suites, and medical device assembly rooms, the way air moves determines whether […]
