The vacuum blasting method, also known as negative pressure blasting, is significantly different from conventional sand blasting. While sandblasting transports the granules with high-pressure on to the surface to be machined, the vacuum blasting method sucks its granulates, by the created negative pressure from the granule container, and accelerates the medium to 400km/h into the jet lance. The high speed of the granules leads to satisfactorily results when removing pollutions and paint. Because of that this minimal-abrasive cleaning technology is also called negative pressure or soft blasting cleaning system. The cleaning equipment is not to be compared with a pressure washer or dry ice blasting.
After turning on, the jet cap (6) is placed on the surface (8) and adheres to it by vacuum. With inserting the jet lance (7) into the jet cap (6) the cycle is closed.
By gravity the granules (2) are passed through from the lower container (1) to a dosing system (3) into the air flow (4). The granules (2) are then transported through a flexible suction house (5) into the jet cap (6). Through the jet lance (7) the granulate impinges on the surface (8) to be worked on. By moving the jet lance (7) the surface can be cleaned quickly and dust-free, stripped or roughened up. The process can be optimally monitored and controlled via 3 vision panels (9). After impinging, the granules (2) and the removed dirt particles are sucked in immediately again. Through the suction hose (10) the abrasive mixture enters the upper part of the machine. There, it is separated by the cyclone principle. The dirt particles are received in the fine dust filter (11) and the granules fall into the middle container. To reuse the granules, the flap (12) is opened and the granules enter the storage container (1). Coarse particles are kept on the screen (13). The work process begins again.
Pros and cons of the vacuum blasting method
Compared to conventional pressure washers the vacuum blasting method of the Tornado ACS has many advantages. Through the high velocity impact hard substances can be broken up and removed. Contamination like limestone or saltpetre can be easily and thoroughly cleaned without any difficulties. In case of soft substances though, the energy is being absorbed. Meaning that pollutions like chewing gum cannot be removed off a surface with this technology. Also for the operation of this cleaning equipment a dry surface is needed.
Concluding, the cleaning machine with its vacuum blasting method Tornado ACS is a great alternative to pressure washers and dry-ice blasting, due to its easiness, accessibility and advantageous applicability. Various application fields of the Tornado ACS make it to the perfect cleaning solution when it comes to green cleaning.
Especially on heritage protected surfaces the minimally-abrasive technology is good to use. The cleaning machine Tornado ACS removes toe pollutes and is gentle to the surface.
