The construction site is one of the dustiest work environments. Cutting, grinding, scarifying, core drilling, demolition: every operation generates dust, and not all dust is the same. Some of it is merely a nuisance, but some is extremely dangerous and must be handled accordingly.
The difference between a well-run site and a badly run one, when it comes to air quality, isn’t about having “a vacuum”. It’s about having the right vacuum for that specific task, with the filtration class suited to the type of dust and the power matched to the work rate. Here’s how to find your way.
Silica dust: the risk many underestimate
When working with cement, concrete, masonry, stone or brick, respirable crystalline silica is released. It’s one of the most insidious dusts in the sector: the finest particles are invisible, stay airborne for a long time and penetrate deep into the respiratory tract. Prolonged exposure is associated with serious lung diseases and is recognised as carcinogenic.
This changes everything when choosing a vacuum, because the most critical dusts need more than just any filter: they require machines with an adequate filtration class, up to class H, the highest, designed specifically for carcinogenic and harmful dusts. Class H is often paired with absolute HEPA filtration. Choosing a lower class than required isn’t a saving, on the other side, it means leaving suspended in the air exactly what should have been captured.
Dust classes at a glance
| Class | For which dusts | Examples in construction |
| L | Low-risk dusts | Coarse debris, non-hazardous inert materials |
| M | Medium-risk dusts (most of the job site) | Cement, concrete, wood, plaster, the majority of operations |
| H | High-risk, carcinogenic or harmful dusts | Crystalline silica, certain fibres, dusts from special operations |
Every site operation has its own vacuum
On construction sites the vacuum almost always works coupled to a tool or a specific operation. The type of dust, the presence or absence of liquids, the volume of material and the need to move around all vary. Here are the most common situations and how iVision handles them.
Grinding, cutting and handheld tools
Sanders, angle grinders, cut-off saws and power tools generate fine dust that calls for agile, portable vacuums to be placed right next to the tool for intermittent or occasional work. The iVision Vacuum single-phase range — models such as GC2 45 WD, GC3 75 WD and GC3 80D — is designed for this kind of use: manoeuvrability, capacity suited to a day’s work, and versatility on dust and, in the WD models, on liquids too.
Large volumes of fine dust and safe disposal
When the volume of fine dust grows, the problem isn’t just extracting it but collecting and disposing of it without re-exposure to the dust. Continuous-bag systems such as the DUSTFREE LONGOPAC and the GC3 D ENDLESS BAG are made for exactly this: the dust ends up in a continuously sealable bag that closes and is removed without releasing anything. It’s the detail that separates a compliant site from one that’s only “clean in appearance”.
Heavy-duty work and structured sites
For heavy-duty applications, intensive use and large quantities of material, the iVision Vacuum three-phase range delivers power and continuous operation. Models such as SAND TR, CLEAN 100 and the VS series (VS 138, VS 175, VS 450, also in the WET & DRY versions) cover the spectrum from heavy dusts to debris mixed with liquids, with the robustness required by prolonged use. The WET & DRY versions are particularly useful where dust and water coexist, as in core drilling, where the cooling water mixes with the residue from the operation.
Special requirements: the tailor-made solution
Some sites pose problems no standard product can solve: hard-to-reach spaces, unusual materials, integration with existing systems. This is where custom configurations come in, engineered around the specific need. It’s the iVision Vacuum principle: where others stop at the catalogue, we design around the problem.
Rely on the iVision Vacuum experts for your construction cleaning system
In construction, extraction is a matter of safety before cleanliness. The right choice starts with the type of dust — silica and fine dusts call for high filtration classes — and runs through the work phase, the rate of use and the way the dust is disposed of. iVision covers the full range of site requirements, from single-phase to three-phase models and on to tailor-made solutions.
