Abstract
Overspray collection apparatus comprises an extraction duct (54) between two sloped floors (50, 52) with unobstructed inlet slots (88, 90) on either side thereof. The extraction duct (54) comprises two moveable panels (56, 58) pivotally mounted to the sloped floors (50, 52). Each moveable panel (56, 58) pivots about an axis that is offset from a lower portion of the moveable panel and a lower portion of the sloped floor. In another embodiment, the pivotal mount comprises an offset hinge. The overspray extraction duct (54) comprises a duct floor (60) and an air diffuser assembly (100) that extends at least partially across the duct floor. The air diffuser assembly (100) receives pressurized air and directs pressurized air into the extraction duct (54), whereby the pressurized air may be pulsed. The overspray extraction duct (54) comprises a suction hood (62) that includes moveable panels (56, 58). Optional actuators may apply a force impulse to one or more of the moveable panels (56, 58), and/or to open and close the suction hood (62) automatically.
