Air Velocity (CFM / ft/min)
CAS Number:
N/A
Air velocity refers to the speed at which air moves through a workspace, including HVAC systems, industrial ventilation, and outdoor environments. In occupational hygiene, air velocity is measured to assess ventilation effectiveness, thermal comfort, and the potential for airborne contaminant dispersal. Excessively high air velocities can cause drafts, increase evaporative heat loss, and impair worker comfort, while insufficient air movement can allow hazardous gases and vapors to accumulate. Monitoring air velocity is a key component of industrial ventilation assessments, clean room qualification, and heat stress evaluations.
Air velocity testing helps confirm ventilation performance in mechanical rooms, process areas, and controlled environments. Rent air velocity meters and airflow tools from RAECO Rents for field-ready testing, with practical support on probes, pitot traverses, and setup for ducts, diffusers, fume hoods, and room airflow. Expect fast turnaround and phone support so you can get usable readings without delays.
