Vaccums for dealing with Hazardous dust | Nilfisk

Hazardous dust

When it comes to workplace safety and the potential danger level of dusts, three classes of dusts considered a risk to health have been identified: L (low risk), M (medium risk) and H (high risk). Nilfisk can provide both filters and machines with L, M or H certification in accordance with the above-mentioned European standard. Nilfisk has also developed a dust containment system for total safety.

Dust: hazardous for health​

Protect your health by using the right industrial vacuum cleaners suitable for the recovery of hazardous dust

Machinery Directive 2006/42/EC applies in terms of the safety levels offered by industrial vacuum cleaners for applications in non-ATEX-classified zones. In particular Normative EN 60335-2-69 is about “Particular requirements for wet and dry vacuum cleaners, including power brush, for industrial and commercial use”; in addition to the constructive and functional requirements, this normative also contains Annex AA referring to vacuum cleaners for hazardous dust. EN 60335-2-69 provides the following defini tion of hazardous dust: “Non-radioactive dust, hazardous to health if inhaled, swallowed or in contact with the skin (see also Directives 79/831/EEC and 67/548/EEC). Micro-organisms are considered dust hazardous to health. Asbestos is classified as one of the above hazardous dusts.”

Nilfisk industrial vacuum cleaners meet the above requirements, offering high safety standards to protect the operator and the environment. In particular, air filtration and dust containment and disposal systems prevent any form of pollution.


Annex AA indicated in the previous paragraph, divides vacuum cleaners for hazardous dust into three Classes of use:

  • Class L - Dust representing a moderate risk - The vacuum cleaner filter traps over 99 % of dust with a grain size of under 2 microns

  • Class M - Dust representing a medium risk - The vacuum cleaner filter traps over 99.9 % of dust with a grain size of under 2 microns

  • Class H - Dust representing a high risk - The vacuum cleaner filter traps over 99.995 % of dust with a grain size of under 1 micron (it includes carcinogenic dusts and dusts contaminated with carcinogens and/or pathogens)

The filtering characteristics are guaranteed by both tests performed on the machine as whole and tests performed on each of the filters installed. A filter efficiency certificate is issued for each machine in Class H.

Nilfisk tests its industrial vacuum cleaners to make sure they meet the above requirements in international laboratories (IMQ, TUV, SLG). In addition to the initial tests done on the product, these bodies also perform periodic tests at Nilfisk to guarantee continuity of performance over time

Nilfisk supplies specific systems to extend the range of materials that can be cleaned using its vacuum cleaners also for extreme situations such as in the presence of liquids, high temperatures, fibrous materials, etc., hazardous dust and materials representing a health risk, or ATEX-classified materials. Ancillary equipment guarantees safety for the operator during collection and disposal.

Disposal and storage

The management of hazardous dust and materials is not limited solely to collection and must also consider disposal management. For this reason, always within the scope of the above EN normative, all Nilfisk vacuum cleaners can be equipped with specific disposable containers or bags to easily dispose of the collected material, such as safe bags or Bag-in Bag-Out systems. Moreover, Class H vacuum cleaners are always supplied with such systems, as required by standard EN60335-2-69.
