ABSTRACT:
A workspace, within a building where a process is practiced by which airborne liquid particulate grease is generated, is ventilated by an apparatus and in accordance with a method by which air is induced to flow at conveying velocity from the workspace into an unrestricted hood and through an unrestricted duct to a location remote from the workspace, entraining airborne liquid particulate grease with the air and thereby unrestrictedly conveying entrained grease from the workspace to the remote location. At the remote location, the flowing air and conveyed grease is directed into a collection chamber and there guided along an at least partially circular, sharply turning flow path while first accelerating and then decelerating the velocity of flow thereby separating the conveyed grease from the flowing air. The separated grease is retained in the collection chamber while the flowing air which conveyed the grease to the chamber is passed to the ambient atmosphere.
