Vacuum Blasting – Eco-Friendly and Future-Oriented Surface Treatment
Vacuum blasting, also known as negative pressure blasting or soft blasting, is an innovative alternative to traditional pressure blasting (sandblasting). It sets new standards in cleanliness, environmental responsibility, and occupational safety.
The patented vacuum blasting technology from systeco enables dust-free, enclosed, and resource-efficient cleaning – without the use of high pressure, water, or chemical additives. This eliminates the need for complex disposal of contaminated cleaning agents and allows even sensitive work areas to be cleaned without risk.
The difference from conventional sandblasting:
While sandblasting propels abrasive material onto the surface at high pressure, vacuum blasting uses negative pressure generated within the blasting hood. The blasting media is drawn directly from the supply container and accelerated through the blasting nozzle at speeds of up to 400 km/h. This high impact speed reliably removes dirt, paint, and coatings – gently and with precision.
Thanks to its minimally abrasive effect, the process is suitable for a wide range of surfaces where conventional methods are either too aggressive or ineffective.
Key advantages at a glance:
- Dust-free, enclosed cleaning system
- No chemicals, no water, no high pressure
- Reusable blasting media
- Ideal for delicate and hard-to-reach surfaces
- Environmentally friendly, safe, and cost-effective
With systeco’s vacuum blasting technology, companies choose a sustainable, efficient, and future-proof cleaning solution – perfect for use in industry, heritage conservation, building maintenance, and many other fields.
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.
