WORK DUST FREE! EVERYTHING YOU NEED TO KNOW ABOUT DUST EXTRACTION
Dust in the workplace is a nuisance. It impacts your customers’ homes, impairs the view of your work, adds to your clean-up time and most importantly poses a health risk. Dust extraction systems are therefore not merely optional but essential. We have put together some essential information for you on dust extraction.

Dust concentration
There are maximum allowable concentrations for harmful dusts in the workplace. These define the maximum concentration of dust in the air we breathe, at which no negative health effects would be expected during a 40-hour working week.

Dust categories
Dust categories are crucial. They indicate the suitability of any given dust and the specified maximum allowable concentrations (MAC). And they define the corresponding filter system's required degree of filtration.
Dust class L: Non-hazardous, harmless dusts such as house dust, plaster and lime. MAC > 1 mg/m³, filter system degree of filtration > 99%
Dust class M: Harmful dusts such as cement, filler, renders, paints and varnishes. MAC > 0.1 mg/m³, filter system degree of filtration > 99.9%
Dust category H: Pathogenic dusts that are carcinogenic (such as asbestos, arsenic and lead) or are contaminated with bacteria, germs or mould. MAC > 0.1 mg/m³, filter system degree of filtration > 99.995%
Dust volumes Dust-free with a system
Sanding drywall in a 90 m² apartment produces up to 54 litres of dust! No one would ingest or inhale an amount such as this by choice – no matter how concentrated, coarse or harmful the dust released may be.
Symptoms
1. Coarse dust particles are generally caught by the nasal hairs or the mucous membranes of the nasopharyngeal space but can cause diseases and irritation there too.
2. Fine dust particles which are inhaled can penetrate as far as the alveoli (air sacs) and cause serious diseases, such as asthma, chronic bronchitis or even cancer.
Festool has the right mobile dust extractor for every application, to suit every dust class and every site of use. No matter whether you're working with the large and powerful CT 48 for workshop areas or the small CTL SYS that you can easily take up on scaffolding when slung over your shoulder: Combined with a SORTAINER and SYSTAINER, mobile dust extractors become mobile workstations.
Dust-free with a method
With Festool, the mobile dust extractors are perfectly designed to work alongside the power tools. The dust is extracted directly at the tool – exactly where it is produced. A positive side effect: Working dust-free significantly extends the life of the machines and consumable materials.
