The world of professional vacuum cleaners is vast

There are two main families of vacuum cleaners between dust extractors and water and dust vacuums. In both cases, and in order to respond to professional use safely, it is imperative to know what level of dust class your use must respect including for the protection of people.
Safety vacuum cleaners
A so-called safety vacuum cleaner is classified according to the European standard EN 60335-2-69 which defines dust classes according to their exposure limit value (ELV). The occupational VLE represents, for a given substance, the maximum permissible concentration in the air of the workplace, where the worker is required to work a full day; it is calculated in relation to an eight-hour reference period, a weighted average over time.
The lower the TLV of a dust, the more dangerous the dust.
