Air Velocity Monitoring Sensors
Validate Clean Airflow, Ensure Containment, and Support Regulatory Compliance
In critical environments such as cleanrooms, biosafety cabinets, compounding pharmacies, and laboratory HVAC systems, the speed and direction of airflow are essential to maintaining sterility, containment, and process integrity. Rees Scientific provides high-accuracy air velocity monitoring solutions that verify performance in these sensitive spaces, helping you protect people, products, and compliance outcomes.
Why Air Velocity Monitoring Is Essential
Air velocity is a foundational element of environmental control, especially in spaces where airborne contamination poses a risk. It ensures that clean air is delivered at the right rate and that contaminated air is effectively exhausted or contained.
- Insufficient or excessive air velocity can lead to:
- Inadequate particle removal and ISO classification failures
- Loss of containment in biosafety cabinets or compounding hoods
- Laminar flow disruption in clean zones
- Filter inefficiencies or HVAC performance degradation
- Failed audits for cleanroom certification, USP <797>/<800>, and FDA GMP inspections
By continuously monitoring air velocity, facilities can proactively detect airflow disruptions and ensure system performance aligns with environmental design specifications.
