  • Blasting device for cleaning a wall
    Patent number: 6244940
    Abstract: In a blasting device, the blasting agent is thrown against the wall to be cleaned. The blasting agent and the dirt removed from the wall are collected in the bottom of the blasting unit in a collection chamber and conveyed by a conveyor to a separation chamber. An extraction device fitted on a suction connection creates air circulation in the blasting device, such that air circulation, the dirt and the blasting agent are separated. The air is supplied through an air supply opening which is placed between the inner seal and the outer seal around the blast opening.
