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 professional ELV represents, for a given substance, the maximum admissible concentration in the air of the workplace, where the worker is required to intervene for an entire day; it is calculated in relation to a reference period of eight hours, weighted average over time.
The lower the ELV of a dust, the more dangerous the dust is.
Difference between L/M and H class
This classification is governed by the standard EN 60335-2-69
L - low risk
Dust with exposure limit value > 1 mg/m3
Non-hazardous dust type such as earth, sand, coating, plaster, paints...
M - moderate risk
Dust with exposure limit value = 0.1 mg/m3 and < 1mg/m3, wood dust.
Hazardous dusts such as wood dust, concrete (quartz based), flour.
H - high risk
Dust with exposure limit value < 0.1 mg/m3, carcinogenic dust, dust loaded with pathogens. Harmful dust, silica, lead, coal, tar, mold, bacteria, asbestos.
H13 same requirement as H often dedicated to asbestos
ATEX Zone 22 - Risks related to explosive dusts St1, St2 and St3 in zone 22.
In any case, we advise you to choose models that offer good ergonomics and ease of maintenance for intensive and professional use. You will find in our Voussert catalog many models of professional vacuum cleaners, which will meet all your needs.

Types of professional vacuum cleaners

Vacuum cleaners for dry dust and Hepa filtration
These professional vacuum cleaners are designed for vacuuming fine dust and dry debris. They are often equipped with advanced filtration systems, such as HEPA filters, to capture the finest particles. Indeed, since the Covid pandemic, the notion of fine suspended particles and in particular viruses have become a major issue in hygiene, thus favoring vacuum cleaners equipped with a H13 type Hepa filter.
Vacuum cleaners for liquids, water and dust
These versatile vacuum cleaners can vacuum both dry debris and liquids. They are particularly suitable for environments where there may be water or liquids spilled on the floor. However, special care must be taken when switching from water to dust by adding the dust filter on certain models so as not to damage the motor. In fact, a water and dust vacuum cleaner is often only dedicated to liquids to avoid this kind of inconvenience. It is therefore best to use a vacuum cleaner for dust and a vacuum cleaner for liquids...
Vacuum cleaners for hazardous waste type class H asbestos
Intended for the collection of toxic materials such as asbestos, dangerous or explosive , these vacuum cleaners are equipped with filters and special containment systems to ensure the safety of the user and the environment. They are often intended for the removal of asbestos from premises and require asbestos kit equipment or disposable category III suit suitable for the user.
Explosion-proof vacuum cleaners type Atex 22
Designed for use in environments with a risk of explosion such as shooting ranges, explosives factories or industries related to weapons, spark zones, and sometimes even in the bakery sector (flour), these vacuum cleaners are manufactured with non-spark producing materials and have specific safety systems to prevent any risk of deflagration in these sensitive areas.
Pneumatic vacuum cleaners
Operating on compressed air rather than mains power, these vacuum cleaners are ideal for areas where electricity is not available or poses an explosion risk.

Frequently Asked Questions About Professional Vacuum Cleaners

How do I choose the right power for my vacuum cleaner?

The power of a professional vacuum cleaner is measured according to three essential criteria:
Electrical power (in watts) : It generally varies between 1,800 and 2,400 watts, for an average useful power of 400 watts.
Air flow (in dm³/s) : This reflects the vacuum cleaner's ability to direct dust to its bin, thanks to the quantity of air that circulates each second.
Depression (in kPa) : This corresponds to the suction speed and allows you to know the suction capacity of the device. The higher the depression, the more powerful the suction will be.
The ideal ratio between air flow and vacuum is around 40 dm³/s for 40 kPa. This ratio makes it possible to evaluate the overall suction efficiency of the vacuum cleaner.

What tank capacity should I choose?

The capacity of the vacuum cleaner tank, expressed in liters, is a determining factor for the autonomy of the vacuum cleaner. It must be selected according to the surface area to be cleaned and the frequency of use:
For occasional use or in restricted spaces, a 10 to 20 litre tank may be sufficient.
For intensive cleaning or large surfaces, opt for a tank of 20 liters or more, in order to limit interruptions to empty the tank.

Which filtration system should I choose?

The quality of filtration plays a crucial role in the efficiency of suction and the purity of the air released by the vacuum cleaner. This element has taken on a large role during the Covid pandemic as part of reducing the airborne spread of micro particles.
There are several options available to you:
Disposable vacuum bags : Practical and hygienic, but requiring recurring purchases of replacement bags. Some bags, such as Numatic bags, are Hepaflo to limit airborne emissions.
Washable vacuum bags : More economical and ecological, but requiring regular maintenance.
HEPA filters : Essential for environments sensitive to allergies and fine dust, they ensure 99.97% filtration of 0.3 micron particles.
