Why is proper hood sizing important?

Hood size directly affects airflow demand, containment efficiency, and system cost. A hood that is too small allows contaminants to escape; a hood that is too large requires unnecessary airflow (CFM), increasing fan horsepower and energy use. Proper sizing ensures the hood captures fumes at the minimum airflow required—reducing operating costs and improving overall system performance. RoboVent uses ACGIH ventilation principles and process-specific engineering to size hoods precisely for each application.
