Abstract:
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.
