摘要: Disclosed is a method for controlling the volume of fluid, e.g., air, moving through duct system, ventilating system vehicle, comprising steps fluid an inlet under dynamic pressure; conducting by means propulsion driven electric motor, wherein current drawn said motor varies with changes in and adjusting amount admitted into response to thus, also responsive pressure, this step thereby maintaining constant air system. Also disclosed apparatus carrying out method.
