US 6,616,720 B1 · Portable airborne contamination control system including a main and remote unit

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 air to a distant location. The invention permits the main unit to be employed independently on easily accessible locations as well as in conjunction with the remote unit in difficult to reach locations. The remote unit may further be adapted to other configurations which would increase its utility.

Dependent claims

A portable airborne contamination control system for collecting overspray, fumes, VOC, and errant particles generated whist treating, coating or blasting a workpiece, said system comprising:

a main unit, said main unit having a motor, an inlet port, and an exhaust port, said main unit adapted to create a vacuum thus creating an upstream and downstream flow between said inlet port and said exhaust port,
an elongated duct, said elongated duct having a first downstream side and a second upstream side,
a remote plenum unit, said remote plenum unit having a downstream exit port and an upstream entrance port,
said elongated duct first downstream side being connected to said main unit inlet port, and
said elongated duct second upstream side being connected to said remote plenum unit downstream exit port,
said remote plenum unit upstream entrance port is in communication with said vacuum and is further adapted to being placed close to a workpiece being treated,
whereby said remote plenum unit is placed in an area which is inaccessible to said main unit, said remote plenum unit placed proximal a workpiece being treated in such a manner where overspray and errant particles are generated, the overspray and errant particles being drawn through said remote plenum unit, further passing downstream through said elongated duct from said second upstream side to said first downstream side, further passing into said main unit inlet port and then exhausted through said main unit exhaust port.
