This category addresses HVAC systems used in GMP facilities, including system design, components, and control of airflow, temperature, humidity, and filtration. It focuses on how HVAC systems support environmental control and product protection in regulated manufacturing environments.
Purpose and Scope Heating, ventilation, and air-conditioning systems support GMP compliance by establishing and maintaining environmental conditions appropriate to the product, process, personnel, equipment, and manufacturing activity. Depending on their intended function, HVAC systems may: HVAC significance is risk-based. Some…
Purpose and Scope HVAC architecture defines how outdoor air, return air, conditioned supply air, and exhaust air move through a facility and how the system controls temperature, humidity, airborne contamination, pressure relationships, and containment. A GMP HVAC system does not…
Purpose and Scope Airflow patterns and pressure relationships control how airborne contamination moves within and between manufacturing spaces. The control objective may include: There is no universally correct airflow direction or pressure hierarchy. Positive pressure is commonly used for product…
Airflow visualization is a qualitative study used to demonstrate how air moves through a cleanroom, controlled area, clean zone, or aseptic processing environment. It provides visible evidence of airflow direction, distribution, interaction with equipment and personnel, and protection of critical…
Temperature, relative humidity, and airflow are related elements of HVAC performance in GMP manufacturing, storage, laboratory, and controlled environments. Their required conditions depend on product and material characteristics, process needs, room use, occupancy, equipment loads, cleanroom classification, contamination-control objectives, containment…
HEPA filtration and air distribution work together to control airborne contamination in cleanrooms, clean zones, and other GMP-controlled environments. The filter reduces the concentration of particles in the supplied air. The distribution system determines where that filtered air travels, how…
