ABSTRACT:
Along the path of the cooking fumes of an exhaust hood where the fumes move with swirling motion, forwardly adjustable blades are disposed between a retracted and an extended position to accentuate or decrease the intensity of the swirling path end of the centrifugal force applied to the particles to be removed, depending on the volume and the flow rate of the cooking fumes which ascend through the hood. This blade arrangement also ensures a constant static pressure inside the hood for a maximum efficiency of extraction.
