Vacuum blasting, vacuum blasting technology, vacuum blasting method, negative-pressure blasting — anyone comparing quotes for professional facade, floor or heritage-substrate cleaning quickly runs into a range of similar-sounding technical terms that are not always used consistently. For facility managers, site managers and municipal clients, that makes comparing quotes unnecessarily difficult.
This glossary defines the key terms of vacuum blasting technology clearly and consistently — as a reference for tenders, specifications and evaluating technical quotes.
The blasting technology industry uses terms inconsistently: what one provider calls "vacuum blasting" another describes as "negative-pressure blasting" or simply "blasting method" — even though technically relevant differences exist. For decision-makers who need to compare quotes or draft a specification, this inconsistency leads to avoidable misunderstandings: a "blasting method" can mean open dry sand blasting without extraction just as easily as the closed vacuum blasting system used in Tornado ACS — with substantial differences in dust exposure, permit requirements and material protection.
The following definitions establish a shared vocabulary — independent of the provider.

An abrasive is the specific blasting material directed against a surface to mechanically remove soiling, coatings or deposits. Abrasives range from fine-grained mineral grits for sensitive surfaces to coarser grades for robust industrial surfaces. The choice of abrasive determines both the cleaning result and how gentle the process is on the underlying material.
Blasting media is the umbrella term for the material used in any blasting process, of which abrasives are the primary example. Selecting the right blasting media depends on the substrate, contamination type and desired cleaning result: finer media for sensitive heritage substrates, coarser media for heavily soiled industrial surfaces.
Dry blasting refers to blasting techniques that operate without added water, in contrast to wet blasting. Classic sand blasting is an open dry blasting method without extraction and generates correspondingly high dust exposure. Vacuum blasting is also a dry blasting method, but differs from open systems like classic sand blasting through its closed design and simultaneous extraction.
The dust extractor is the filter and extraction unit within a vacuum blasting system that captures dust and removed material generated during blasting and separates it from clean abrasive. A capable dust extractor is the technical precondition for vacuum blasting's near dust-free operation — a key difference from open blasting methods without extraction. Regular maintenance and filter cleaning are essential for sustained performance.
Tornado ACS is Systeco's patented vacuum blasting system. The name refers to both the cleaning process and the machine technology developed for it: a closed system that directs abrasive against the surface in a controlled manner and simultaneously extracts dirt and abrasive by negative pressure — without high pressure, without water, without chemicals. A detailed technical explanation is available in the article Tornado ACS Explained.
Vacuum blasting refers to a blasting process in which abrasive is directed against a surface within a closed system and, while the process is underway, extracted again by negative pressure — together with dirt and dust. This fundamentally distinguishes vacuum blasting from open blasting methods such as classic sand blasting. Result: controlled, near dust-free cleaning without water and without chemicals.
The vacuum blasting method is the concrete application of vacuum blasting technology to surface cleaning: a closed loop of controlled abrasive delivery and simultaneous extraction by negative pressure. Unlike alternative blasting methods such as sand blasting, the vacuum blasting method operates near dust-free and protects the underlying material. A direct comparison of methods is available in the article Vacuum Blasting vs Sand Blasting.
Vacuum blasting technology is the technical umbrella term for the full set of processes, machinery and components used in vacuum blasting — from the blasting head through the dust extractor to the control unit. The term is often used interchangeably with "vacuum blasting method," though in the narrower sense it refers more to the technical discipline than to the specific application. Systeco, with the Tornado ACS vacuum blasting method, is recognised as a reference point for this technology.
In wet blasting, water is added to the abrasive to reduce dust generation. The process, however, produces wastewater that, depending on contamination and abrasive used, is often considered contaminated and must be disposed of properly. For water-sensitive materials such as historic brick or natural stone, wet blasting is frequently unsuitable, since moisture penetrates the pores. Vacuum blasting achieves comparable dust reduction without water and therefore without a wastewater problem.
Anyone comparing quotes for vacuum blasting, vacuum blasting technology or the vacuum blasting method should pay attention to precise use of terminology — it often reveals more about actual process quality than the price alone. A provider who can clearly name the abrasive, the dust extractor and the process typically also has the technical competence to execute the method correctly.

Vacuum blasting technology is the technical umbrella term for processes, machinery and components that direct abrasive against a surface within a closed system while simultaneously extracting it by negative pressure. It enables near dust-free, material-friendly cleaning without water and without chemicals.
Sand blasting is an open dry blasting method without extraction — abrasive is thrown against the surface, and dust and residual material disperse uncontrolled into the environment. Vacuum blasting operates within a closed system: a sealing blasting head and simultaneous extraction by negative pressure prevent dust and abrasive from escaping.
An abrasive is the blasting material mechanically directed against a surface to remove soiling. The grit size and material type of the abrasive are selected according to the substrate and depth of contamination.
The dust extractor is the filter and extraction unit of a vacuum blasting system. It separates dust and removed material from clean abrasive during blasting, making the near dust-free operation of vacuum blasting possible in the first place.
Wet blasting adds water to the abrasive to bind dust, but this generates wastewater and makes the method unsuitable for water-sensitive materials. Dry blasting operates without added water; vacuum blasting is a dry blasting method that achieves dust reduction instead through a closed design and simultaneous extraction.
Vacuum blasting technology is the technical umbrella term for the entire process category. Tornado ACS is Systeco's patented vacuum blasting system — a specific, trademarked implementation of this technology, not the technology itself.
Providers do not always use terms like "blasting method" or "vacuum blasting" precisely. A tender that clearly specifies which method is meant prevents quotes for different technologies (for example open sand blasting instead of closed vacuum blasting) being submitted under the same label — and protects against unwelcome surprises around dust exposure, permit requirements or material damage.
