Abstract
An apparatus for the capture of overspray, blast media particles, and errant particle generated during spraying without employing an enclosure is disclosed. The apparatus is to be employed proximal a worker on a platform. The overspray capture mechanism is located intermediate the platform and the object being sprayed of coated. The mechanism includes a centrally supported suction duct which exerts a negative pressure in the area, the duct extends from the work area to a filtration area proximal a pump. A generally rectangular, flexible capturing device surrounds the duct. The flexible capture device is located intermediate a first and second support. The first and second supports include hydraulic elements which control the position of the supports and hence the flexible capture device. By use of the capturing device, liquid buildup, overspray or errant particles will be caused to move to and into the suction duct and then to a filtration system. In this fashion, the overspray and errant particles would be channeled into a filtered area and no physical enclosure is required proximal the spraying area.
