Abstract: A color changer has a common feed passage that is connected to two or more inlet passages. The common feed passage can be reverse purged in a direction that is opposite a direction of powder flow through the common feed passage. A valve element seals a supply port that connects the inlet passage to the common feed passage to eliminate dead space and form a near bore line seal. The valve element is an elastic material that expands in response to applied compressed air inside the valve element.

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).

Abstract: A nozzle for a powder spray gun optionally includes an internal filter that allows air to be added to the powder flow within the nozzle shell. The nozzle may optionally include an off-axis outlet slot relative to a main flow axis of the powder into the nozzle shell so that powder encounters an obstruction before exiting through the outlet slot.
