WebOct 2, 2024 · What is face velocity? ASHRAE 110 defines face velocity as the average velocity of air moving perpendicular to the hood face, usually expressed in feet per minute (FPM) or meters per second (MPS). It is a simple measure of air going into the fume hood. In the Laboratory Ventilation Standard, ANSI/AIHA Z9.5 (page 22) it says: WebFace Velocity is a measurement of the speed at which air enters a fume hood’s face opening. It is generally recommended that a fume hood’s face velocity is between 0.3 …
