Face velocity is the measured air speed at an inlet or outlet of a heating ventilation and air conditioning (HVAC) system.

In a laboratory setting, a fume hood is a ventilated enclosure that is used to safely handle harmful or toxic fumes or vapours. By drawing air up into the fume hood, airborne contaminants can be captured, contained and removed, preventing harm to technicians.

Airflow into a hood is achieved by an exhaust blower which ‘pulls’ air into and through the hood and exhaust system. This ‘pull’ at the opening of the hood is measured as face velocity.
