A system (1), for shot blasting of a surface, collecting used shot blast media and debris, and separating the debris from the shot blast, has at least one shot blast nozzle (105) with a hood (100) connected to a vacuum hose (110). The system further has a displacement chamber (200) with an inlet connected to the hood by the vacuum hose, an inlet baffle (220), a solid matter collecting and discharging area (205) for receiving solid matter which falls from the gas stream in the displacement chamber, an outlet baffle (225), an outlet (226) for the outgoing gas stream, and a rotary valve (510) for allowing discharge of the solid matter. A first filter unit (300) and a second filter unit (310) are connected to the displacement chamber via a first duct (230). A shot blast media container (600) is connected to a shot blast media feeding hose (120), which is connected to the shot blast nozzle. Further, a blower (400) creates suction of the gas stream from the shot blast nozzle to the displacement chamber, through the first filter unit and the second filter unit. A vibratory screen separator (500) is arranged adjacent the rotary valve and is arranged to separate used shot blast media from larger particles. A paint and dust filter (700) is connected between the first and second filter units and the displacement chamber, for filtering the filtrate from the filter units. The paint and dust filter utilizes the blower suction from the displacement chamber to suck the filtrate from the filter units. |
