Vacuum blasting - eco-friendly and trendsetting

Vacuum blasting, also calles negative pressure blasting, differs considerably from conventional pressure blasting, also called sand blasting.

The unique vacuum blast technology enables clean and eco-friendly work. The clenaing system is set up in a few minutes and ready to operate. The costly disposal of polluted cleaning detergents doesn´t apply, since it is cleaned without high pressure, water and chemicals. Whenever common methods fail, the vacuum blasting of systeco comes to use.


During the sandblasting process, the blasting media is pressurized to the surface to be treated, the granulate is drawn out of the storage container by the generated negative pressure in the blasting hood and accelerates to 400 km / h in the jet lance. The high impact speed of the blasting media dissipates dirt and paint quickly from the surface. This minimal-abrasive vacuum blast is therefore also referred to as a vacuum or soft-blast process.


 

Functioning

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.
