Abstract
The invention is an airborne contamination control system with a main device unit and a remote unit. The main airborne contamination control unit is a cabinet including a motor in communication with an air treatment path. The main unit has a variety of configurations. The main unit has the capability to be connected to any of a plurality of lightweight remote units, depending on the specific application. These remote units are highly portable and of a small dimension which permits them to be employed in areas inaccessible to the main unit. The main unit is connected to the remote unit by an elongated and flexible duct. Both the main unit and remote unit have a general cabinet structure with mounting structure designed to receive dual or single articulated suction ducts thereon. The articulated suction ducts may be placed proximal a work piece which is being coated, abraded or treated by spraying. The articulated suction ducts collect overspray and errant particles and transports them to and through a filter located in the main unit. The filtered air is then exhausted through an exhaust port on the main unit. An elongated duct may be connected to the exhaust port to transport the ai…
