Festool on the dangers, safety and importance of filtration and classes of dust. For health reasons, longer tool life and work quality

Festool have the largest comprehensive range of technically advanced dust extractors available knowing how important dust free sites and workplaces are to the industry

Festool Dust Extractors keep the workplace safe and healthy for all workers, offering numerous versions of extraction systems

“There are 3 grades of filtration: CTL – 99%, CTM – 99.9% and CTH – 99.995% The filtration requirement is based on the particle emitted vs the particle sucked up.” said Greg de Villiers Technical and brand manager for Festool at Vermont Sales says. “A dust-free environment is also indispensable for health protection and occupational safety. There is a demand for mobile extractors which can be used for various dust classes, achieving outstanding performance, are easy to transport and move around the professional mobile dust extractors are an indispensable part of the intelligent workplace system,” said de Villiers.

Whether cutting, sanding, sawing, or routing and working with all types of materials, dust is produced as part of day-to-day operations in workshops, on construction sites and at other mobile operating sites. However, a dust-free working environment is indispensable to ensure that your work produces good results. If dust settles on the workpieces, this is guaranteed to impair quality. It has also been proven that tools from which dust is actively extracted have a significantly longer service life. When working without dust extraction, tradespeople breathe in the substances, some of which are hazardous. This poses a health risk.

It important to know the various dust classes

Low Risk (L-Class) Low-risk dust includes simple house dust and materials such as soils. This type of dust presents a moderate risk to any operator as the exposure limit for L-Class dust is >1mg/㎥. This dust class requires a dust extractor that catches 99% of the dust with a grain size under two microns.

Medium Risk (M-Class) Medium risk dust includes wood dust, dust from repair compounds, filler and clear coats, cement, concrete and tile cement dust, quartziferous materials such as sand and pebbles. This type of dust presents a medium risk to any operator as the exposure limit for M-Class is > 0.1mg/㎥. This dust class requires a dust extractor that catches 99.9% of the dust with a grain size under two microns.

High Risk (H-Class) High-risk dust includes any dust containing carcinogenic or pathogenic particles, as well as any mold spores, asbestos, mineral fibers, bitumen, and artificial mineral fibers such as glass wool. This type of dust presents a high risk to any operator as the exposure limit for H-Class dust is >0.1mg/㎥. This dust class requires a dust extractor that catches 99.995% of the dust with a grain size under one micron.

Although all classes pose a risk to human health, one of the more common and dangerous types of dust to watch out for is Silica dust. This dust only requires a small amount to be airborne to create a health hazard, and the particles are not visible to the human eye. If inhaled, Silica dust can cause serious damage to the lungs, kidneys, and airways.

The different dust extractor types

In addition to the dust class, the size of the dust container plays an important role too and works well on construction sites, while large-capacity dust separators are the better choice for workshops. There are two basic types of dust extractor – machines that offer AUTOCLEAN and machines that do not. Machines with a AUTOCLEAN functionality has the ability to automatically clean the main filter at regular intervals and ensure consistently high suction power. Machines of this type are practical for handling large amounts of fine dust, which accumulates when using long-reach sanders or restoration/diamond sanders.

A filter bag is necessary to operate units without AUTOCLEAN. There is a mobile dust extractor to suit every need: The range varies from highly compact extractors for use on the move to all-round models for construction sites, garages, homes and workshops, not forgetting extractors with automatic, infinitely adjustable filter cleaning systems and special extractors such as the H extractor for hazardous dusts (asbestos, mould) or extractors for Zone 22 used for working with flammable and explosive dusts.

The comprehensive range of Festool dust extractors also boasts another innovative feature, the AUTO function gives the user the ability to select between AUTO and MANUAL) function allowing your dust extractor to be turned on simultaneously as your power tool is powered on.
